7 1 Approval/Calculation This chapter provides an overview of Approval & Calculation functionality of Oracle Retail Allocation. Overview The approval process in Allocation is now an offline process like Calculation. Instead of immediately approving/reserving an allocation when a user changes the status in the Alloc Summary page, now the approval/reserve request is submitted to the Calculation Queue after saving the allocation in the Alloc Summary page. The Calculation Queue then picks up the queue item and the status is then processed. Various functional changes in the Calculation process are also described in this document. Detailed Discussion Configurable Calculation Queues In order to take the approval process offline, the Calculation Queue was changed to support multiple administrator-defined queue types with a single queue. One queue can now perform standard calculations, pre-pack calculations, recalculation, and approval all while using the same queue processes. Conversely, approvals and standard calculations can now run on different queue processes. As per previous versions of the queue, batching and the ability to assign a name to a queue and have multiple queues running at the same time remains. The following parameters are now used when starting the Calculation Queue: approval, standard_calculation, prepack, and recalculation. For example, the following would start a Calculation Queue that processes all calculation types supported: queue_10.bat start <queue_name> -standard_calculation approval prepack recalculation New Calculation Statuses in Approval Process The new approval process runs in the background. The various statuses of the approval process are: 1. Status Waiting Calculation Status = Status Waiting, Allocation Status = Approved. This status indicates that the approval process is in the queue. The actual approval process has not started and no records can be found in the database. The user will not be allowed to enter the allocation summary. 2. Status Processing Calculation Status = Status Processing, Allocation Status = Approved. This status indicates that the queue has picked the allocation for approval and is still processing it. The user will not be allowed to enter the allocation summary. 1

8 Detailed Discussion 3. Status Processed Calculation Status = Status Processed, Allocation Status = Approved. This status indicates that the approval process has been completed successfully. The Allocation-Xref-RMS records will be available. The user is allowed to enter into the allocation summary for any updates. 4. Status Error Calculation Status = Status Error, Allocation Status = Worksheet. The status reports, that an error has occurred while processing the allocation for approval. The error could be due to any validation failure or any other system failure. The error can be determined in the log files present in the system. Validation for Approval in Allocation 10.0.x Specific Validation Types This document describes the validation that is performed during the approval process in Allocation 10.0.x. Validation is performed when an allocation is submitted to the calculation queue and once again during the actual approval process. If validation fails during submission in the Allocation summary page, the user will receive a popup message with a specific message. If validation fails during the actual approval process in the calculation queue, a detailed message is logged and the user will see the following generic approval failed message when that allocation is opened. An error occurred while approving your allocation. Contact your system administrator for details. Message bundle key: AllocSummary.approve_failed Find below the specific validation types that are performed: 1. Release Date Before the Current Date This validation type, validates the release dates of the item sources that are greater than the current date. If the release date of any one of the item source in the location falls before the current date (today s date), then processing is stopped and the following message is popped up or logged: Release date should be equal or after today s date. Message bundle key: ProdDetailsView.releaseDate_before_CurrentDate 2. Release Date Before the PO s Not Before Date Validates that release dates that are greater than the not before date of the PO. If the release date is before the not before date then the following message is logged/displayed: The PO Not Before Date, {0}, is after the Release Date, {1}. Message bundle key: ProdDetailsView.releaseDate_before_PONotBeforeDate 2 Oracle Retail Allocation

9 Detailed Discussion 3. PO Available Quantity Validation Validates against Orders for available quantity. If available quantity is 0 (if the PO has been exhausted by some other approved allocation) processing is stopped and the following message is logged/displayed: This Allocation contains a PO based Item Source. This item is with either zero available quantity or available quantity less than the allocated quantity or both. Remove the Item Source or recalculate and approve. Message bundle key: AllocSummary.invalidPO 4. Warehouse Available Quantity Validation This validation type validates against the Warehouse for available quantity. If available quantity is 0, then the processing is stopped and the following message is logged/displayed: This Allocation contains an item with either zero available quantity or available quantity less than allocated quantity or both. Remove the Item Source or recalculate and approve. Message bundle key: AllocSummary.invalidWH 5. Invalid Item Location Validation Validates locations that are in a valid status (not C, I or D), and that the store is open by verifying that the current and release dates are greater than the store close date. If any invalid item location is found, then the processing will be stopped and the following is logged/displayed: Status cannot be changed until all invalid item/locations are resolved. Click OK to view the invalid item/locations. Message bundle key: AllocSummary.invalid_item_locs Functional Changes in Calculation Quantity Limits effects when item sourced from multiple warehouse and store enforce flag = N with one or more stores. When creating an allocation the user has the ability to set the sum(min) value for an item in the Quantity Limits page be less than or equal to the total available quantity for the item. In multiple warehouse scenarios the total available qty = sum of the available quantity from all warehouses for the item. In that case, the total available quantity can be greater than the available quantity in the individual warehouses. Calculation is performed for an item per warehouse wise. Setting up total min > available quantity will lead to no store getting any allocated quantity. In such a scenario the system will now reduce the min value according to the available quantity at that particular warehouse. By doing this, the stores will get allocated. Approval/Calculation 3

10 Detailed Discussion Manual Rule will have a new default parameter setup. This is put in place so when the allocation is changed from non-manual Rule setup to a Manual Rule the old setup does not remain. This causes a problem for Fashion item sources where Recalculation needs to occur when final quantity is changed. The default parameter setup is: ruletype = Rule.TYPE_MANUAL; rulelevel= null; exactind = "Y"; cascadeind = "N"; netneedind = "Y"; userulelevelonhandind = "N"; includeclearancestockind = "N"; regularsalesind = "N"; promosalesind = "N"; clearancesalesind = "N"; includeinvinminind = "Y"; includeinvinmaxind = "Y"; fromdate = null; todate = null; fromdate2 = null; todate2 = null; onordercommitdate = null; wksfromtoday; templateid=null; corporateruleid; thisyear = -1; lastyear = -1; Manual rule will display the net need for an allocation 0 even if there is stock on hand available for an item. The following changes were made: The need for the store in the allocation will be replaced by the need of the sister store, if the store in the allocation has no need (ignoring when need=0 or negative) for the particular EOW_DATE. The net need value for an item in What-If and Cascade Mode will bear an * in allocation summary and view details. When doing a Cascade Allocation with RLOH = Y and Net Need = Y, the Gross Need will include the RLOH in the calculation. The gross need for individual item in the allocation in Cascade mode is calculated based on the formula: [[(Store Allocated Qty + CascadeStoreOnHand) * (Available quantity for item + skuonhandatallstore)] / (TotalOnHand + TotalAvailable) ] * storesum 4 Oracle Retail Allocation

11 Impact Analysis Impact Analysis Allocation Summary Store allocated Qty = Quantity allocated in first pass at hierarchy level CascadeStoreOnHand = SOH for all items in allocation in the store Available quantity for item = Actual available quantity for the item skuonhandatallstore = Total on Hand for the item in all the store in allocation. TotalOnHand = Total On Hand for all the items in allocation TotalAvailable = Total Available for all the items in allocation Storesum = 1 if calculated value > 0 else -1 Allocation Summary and Approval are impacted by these changes. Allocations will no longer be immediately approved when the status is set to Approved. When the allocation is saved on the Allocation Summary screen, the application will submit a status change request to the calculation queue. Approval After submitting an allocation for Approval, the user will be taken to the portal screen and the allocation will not be accessible until the status is processed by the calculation queue. Data Model Change None. Approval/Calculation 5

13 2 Algorithm Overview Analysis This chapter describes the difference between the documented rounding example in the previous operations guide and how the algorithm actually works till Following are the two differences in the documented and production algorithm as well as in problem setup, which explain the different results. Testing Problem Differences Algorithm Differences The test problem (SKU Constrained analysis) and the documented sample problem is not the same set up which triggers different run path within the allocation algorithm. SOM = 1 in the documented problem while SOM = 4 in the test problem. What that means is that we allocate SKU s in the sample problem and item pack of size 4 in the test problem. For the test problem, the first step of the allocation algorithm is to convert on hand and desired stock that is in SKU s to item packs. E.g., OH of 6 SKU s is converted to OH of 1.5 packs and desired stock of SKU s is converted to desired stock of 2.97 packs. The algorithm described in previous operations guide is meant to illustrate the idea of the allocation algorithm, it is NOT the same with the allocation algorithm that are put in production (production algorithm). For numerical, stability and business reasons, the production allocation algorithm rounds the desired stock so that the difference between desired stock and on hand is an integer. E.g., with original OH of 1.5 packs and desired stock of 2.87 packs, we have a need-toship of = 1.37 packs which is not integer. To make it integer, we round the desired from 2.87 to 2.5 which give us need-to-ship of 1 pack. An internal cutoff parameter (currently hard coded to 50%) is used to control when to round up and when to round down. When we have a residual that is more or equal to the cutoff percent of a SKU (pack), we round up. E.x., for a 50% cutoff percentage, the need-to-ship of 1.37 packs has a residual of 37% of a pack, so it is rounded down to 1 pack, and a need-to-ship of 1.51 packs is rounded up to 2 packs because of the 51% residual pack. This massage of the desired stock is insignificant when the numbers of OH and desired stock are big enough, but not in the test problem when OH and desired stock are small numbers like 0.75 and Algorithm 7

14 Solution Focusing the Four Stores in Question The following table illustrates as to whythe store 761 and 586 got allocated rather than the store 580 and 784. In the first scenario where SOM = 1, store 580 and 784 has low DSR s. But in the second scenario where SOM = 4, the converting and rounding described in the previous two sections skewed the low DSR to store 761 and 586. Store # OH ( on hand ) Desired Stock DSR (OH/Desired Stock) DSR RANK OH' (OH / SOM) Desired Stock' (Desired Stock / SOM) Need' (Desired Stock OH ) Rounded Need' ( 50% cutoff ) Rounded Desired Stock' (OH + Rounded Need ) DSR' DSR RANK Solution In the dealing phase, after we have already allocated the truncated SKUs (item packs), we use TSR [truncated stock target ratio = (on hand + truncated ship) / rounded desired stock] to guide the allocation of truncated SKU s (item packs) to stores. To honor the original stock target ratio, we could use original desired stock in the TSR calculation. This change will produce desired allocation to store 761 and 586 in the testing problem. This option has been implemented and put in production code as a bug fix. 8 Oracle Retail Allocation
