Cut Over Activities Specific for LIS* Data Sources Applies to: SAP BW 3.5/SAP BI 7.0. For more information visit the Enterprise Data Warehousing Homepage Summary The basic purpose of this document is to explain all the basic activities to be taken care of while performing the cut-over of an LIS* data source. In other words, the document will give you details of the things to be done before you move LIS* data source (enhanced or otherwise) to the production environment.

Overview: LIS stands for Logistics Information Systems. The purpose of this document is to brief about the steps to be taken with regard to LIS data sources before and after any planned maintenance to the ECC component. These activities are required to be performed to ensure that no data is lost. What are the Cut over Activities? Typical cut over activities for LIS data sources include the following: 1. Clearing the BW Delta Queues for LIS extractors in ECC. 2. Clearing the Outbound Queue in ECC. 3. Processing of Delta Queues. 4. Deletion of setup tables. Now we will look at each step in detail Clearing the BW Delta Queues for LIS extractors in ECC The Delta Queue can be accessed by T-Code RSA7 in ECC. There you would be able to see the name of the LIS data sources and the records in the Total column as shown below. We can clear the queues by triggering the Auto (Delta) manually. Once a particular queue is cleared the total column would show zero. For example for the data source 2LIS_06_INV we see 13 in the Total column. Once the Auto (Delta) info package is triggered and the queue is cleared we would see 0 in the total column as shown below. 2011 SAP AG 3
This sums up the step, Clearing of BW Delta Queues. Clearing of Outbound Queues in ECC The Extraction Queue s that needs to be cleared can be identified using the T-Code LBWQ. If we go to LBWQ, we would see the Queue s waiting to be cleared as shown below. Now for clearing the extraction Queue s we need to either execute the V3 collective job using T-Code SE38 or by scheduling the job immediately using the transaction LBWE. Clearing the Extraction Queue s by executing the V3 collective job using T-Code SE38: a.) Go to T-Code SE38. b.) The program to be used is RMBWV3XX. XX here stands for the application number. Suppose if you want the clear the Extraction Queue for Application 02, then the program name would be RMBWV302. Take another look at the above screenshot of Outbound Queue s and you would notice one entry which reads MCEX17_1. What should the Program name be for clearing this queue? The program name is RMBWV317, same as the one used for clearing MCEX17. Here is the list of all program names for the above shown applications for convenience. Program RMBWV302 (Clears queue MCEX02) Program RMBWV303 (Clears queue MCEX03) Program RMBWV304 (Clears queue MCEX04) Program RMBWV305 (Clears queue MCEX05) Program RMBWV306 (Clears queue MCEX06) Program RMBWV308 (Clears queue MCEX08) Program RMBWV311 (Clears queue MCEX11) Program RMBWV312 (Clears queue MCEX12) Program RMBWV313 (Clears queue MCEX13) Program RMBWV317 (Clears queue MCEX17 & MCEX17_1). 2011 SAP AG 4
Clearing of Extraction Queue s by scheduling the job using T-Code LBWE: a.) Go to LBWE. The screen will look as shown below. b.) Click on Job Control for the application for which you want to process the extraction queues. c.) Schedule the job as immediate. The LUV s or entries in the Extraction Queue would be processed. This completes the second step i.e., clearing of Outbound Queues. Processing of Delta Queues After clearing the Outbound Queue, the Delta Queue s which needs to be processed can be seen using the T-Code SMQ1. It would be something similar to the below screenshot. Now again trigger the Auto (Delta) info packages under each data source to fetch data to BWP. The info packages should be triggered till we see two empty records in the PSA (a best practice). This completes the third step i.e. processing of Delta Queues. 2011 SAP AG 5
Deleting the Setup Tables How to check if the setup tables needs to be cleared? By using the Program RMCEXCHK via T-Code SE38, we can check what all setup tables can be cleared. Have a look at the screenshots Now as seen from the above screenshot, we can see that setup tables needs to be cleared for applications 02, 03, 04, 06, 08, 11, 12, 13, 17. 2011 SAP AG 6
How do we delete the data from the setup tables? There are two ways to delete the contents of the setup table - a.) By using t-code SBIW b.) By using program RMCSBWSETUPDELETE By using t-code SBIW Go to t-code SBIW. Go to Delete the contents of the setup table using the following flow Settings for Application-Specific Data Sources (PI) Logistics Initialization delete the contents of the setup table. It is shown in the below screenshot After clicking execute, the new screen would ask to input the application as shown in the next screenshot- Say for example, you want to delete application 02, enter it in the above screen as shown below and execute it. 2011 SAP AG 7
This ensures that all the setup tables for application 02 are emptied. Repeat this step for all the applications which are showed in the check. By using program RMCSBWSETUPDELETE By using the program RMCSBWSETUPDELETE via T-Code SE38, for the selected application we can delete the data for that application. It is shown below. After clicking execute, the new screen would ask to input the application as shown in the next screenshot- Say for example, you want to delete application 02, enter it in the above screen as shown below and execute it. This ensures that all the setup tables for application 02 are emptied. Repeat this step for all the applications which are showed in the check. This completes the step of deleting setup table data. 2011 SAP AG 8
