Purpose: This article addresses the requirement of Nested Exception aggregation in BW/BI Reports; In this article I m going to explain the following list: How to use the formula variables with replacement path as processing type. How to use IF ELSE condition in the calculated Keyfigures. How to create and use Nested Exception Aggregation. Report Requirements: In some sales based reports, Users wants to see the Total number of deliveries, On-time deliveries, early deliveries and Late Deliveries for particular time period. To display the data as per above requirements we have to create Calculated Keyfigures to count the delivery numbers based on Actual Delivery Date and Requested Delivery Date of Delivery number. On-time Delivery: An On-time Delivery is a delivery number whose Actual Delivery Date is equal to Requested Delivery Date. Late Delivery: A Late Delivery is a delivery number whose Actual Delivery Date is greater than Requested Delivery Date. Early Delivery: An Early Delivery is a delivery number whose Actual Delivery Date is less than Requested Delivery Date. 2011 SAP AG 3
Counting total number of deliveries: To count the delivery numbers we need a formula variable to hold the Delivery number for each record and that formula should process with Replacement path with Delivery number (0DELIV_NUMB) as reference Characteristic. Step 1: Create a Calculate Key Figure - Number of Deliveries Step 2: Give the Description and technical names as Number of Deliveries and CKF_NO_DEL_1 respectively and create a new Formula Variable to hold the Delivery numbers. 2011 SAP AG 4
Step 3: Create ZVAR_DEL_NUMB formula variable Description: Type of Variable: Processing by: Reference Characteristic: Delivery Number Formula Replacement Path Delivery (0DELIV_NUMB) Set the Replacement Path attributes with below settings: 2011 SAP AG 5
This formula is not ready for input (Don t Check Variable is Ready for Input) Set the Dimension as Number (Delivery number is numerical field): 2011 SAP AG 6
Step 4: Drag and drop the Delivery Number (ZVAR_DEL_NUMB) formula variable into the Detail view of Number of Deliveries (CKF_NO_DEL_1) Calculated Key Figure. Use default aggregation type Standard Aggregation as Exception Aggregation 2011 SAP AG 7
Comparing Date values: Create two different formula variables with Replacement Path as processing type and having Actual Delivery Date and Requested Delivery Dates as reference characteristics. Formula variable with Actual Delivery date as reference characteristic: Description: Technical Name: Type of Variable: Processing by: Reference Characteristic: Actual Delivery Date Formula VAR_ACT_DEL_DATE_FORM Formula Replacement Path Actual Delivery Date (0ACT_DL_DTE) In the Replacement Path tab, select the Replace Variable with attribute as InfoObject and replace with Key value. The Off set values for date field starts with 0(Zero) and the length should be 8. 2011 SAP AG 8
Don t Check the Variable is ready for Input Set the Dimension as Date in the Currency/Unit tab 2011 SAP AG 9
Similarly create another formula variable with Requested Delivery date as reference characteristic: Description: Technical Name: Type of Variable: Processing by: Reference Characteristic: Requested Delivery Date Formula VAR_REQ_DEL_DATE Formula Replacement Path Requested Delivery Date (0DSDEL_DATE) In the Replacement Path tab, select the Replacement Variable with attribute as InfoObject and Replaced with Key value. The Off set values for date field starts with 0(Zero) and the length should be 8. 2011 SAP AG 10
Don t Check the Variable is ready for Input Set the Dimension as Date in the Currency/Unit tab Now we can compare Acutal Delivery date with Requested Delivery date value by using logical operators example: =, <,>, <=,>=.. Date Difference = Actual Delivery Date Formula (VAR_ACT_DEL_DATE_FORM) - Requested Delivery Date Formula (VAR_REQ_DEL_DATE). 2011 SAP AG 11
How to create IF then ELSE Conditions in Calculated Key Figures: General IF ELSE Condition: IF <Condition> <Statements> (is true) (Execute the statements block) ELSE IF<Condition> <Statements> ELSE IF<Condition> <Statement> IF ELSE Condition Example: We can write IF then Else statement for different comparisons in Calculated KeyFigure / Formula. Example: (A ==B)*C + (A>B) *D + (A<B) * E Statements gives different results for different values of A & B. Case 1: IF A == B is True The Statement becomes (1) * C + (0) * D + (0) * E Result is C. Case 2: IF A > B is True Then the statement becomes (0) * C + (1) * D + (0) * E Result is D Case 3: If A < B is True Then the statement becomes (0) * C + (0) * D + (1) * E Result is E. Counting On-time Deliveries: To count On-time Deliveries we have to compare Actual Delivery Date with Requested Delivery date. If both dates are same then only we should consider that delivery number. Create a new calculated keyfigure On-Time Del (CKF_ON_TIME_2) and drag and drop the Actual Delivery Date and Requested Delivery date formula variables into the Detail view. 2011 SAP AG 12
Formula to count On-time Deliveries: On-Time Deliveries = ([VAR_ACT_DEL_DATE_FORM] Actual Delivery Date == [VAR_REQ_DEL_DATE] Requested Delivery Date) * [CKF_NO_DEL_1] Number of Deliveries Set the Exception Aggregation value to TOTAL and Reference Characteristic Requested Delivery date. Exception Aggregation as Total : As the name signifies, this function is used to aggregate the result of a key figure in a different manner than standard OLAP functionality. It works same as Standard Exception Aggregation but summarized keyfigure with respect to the Reference Characteristic. Similarly create Late deliveries and Early deliveries calculated keyfigures to count Late and Early deliveries. 2011 SAP AG 13
Counting Late Deliveries: Create a new Calculated Keyfigure Deliveris Late (CKF_DEL_LATE_4) and drag and drop required formula variables into the Detail view of CKF. Formula to count Late Deliveries: Deliveries Late = ([VAR_ACT_DEL_DATE_FORM] Actual Delivery Date > [VAR_REQ_DEL_DATE] Requested Delivery Date) * [CKF_NO_DEL_1] Number of Deliveries Set the Exception Aggregation value to TOTAL and Reference Characteristic Requested Delivery date (0DSDEL_DATE) 2011 SAP AG 14
Counting Early Deliveries: Create a new Calculated Keyfigure Deliveris Early (CKF_DEL_EARLY_6) and drag and drop required formula variables into the Detail view of CKF. Formula to count Early Deliveries: Deliveries Early = ([VAR_ACT_DEL_DATE_FORM] Actual Delivery Date < [VAR_REQ_DEL_DATE] Requested Delivery Date) * [CKF_NO_DEL_1] Number of Deliveries Set the Exception Aggregation value to TOTAL and Reference Characteristic Requested Delivery date (0DSDEL_DATE) 2011 SAP AG 15
Result of Default Aggregation Standard Exception Aggregation : If we are not using Exception Aggregation as Total then the Calculated Key figures uses Standard Aggregation then the report result is as below: Report Result: Place Actual Delivery date and Requested Delivery dates in the columns of BEx designer of the report for detail analysis of above error, then the report result will be as follows: 2011 SAP AG 16
Report result: As per above screenshot, we can understand that On-time, Delivery Late and Delivery Early are not summarized at Actual, Requested Delivery date levels. In order to get summarized result we have to use TOTAL as an Exception Aggregation type with respect to dates. Here we need nested exception aggregation to get correct results. i.e first we have to create one Calculated Keyfigure with TOTAL Exception aggregate with reference to Requested Delviery date and then create another Calculated Key Figure/Formula and call the earlier CKF(with Requested Delivery date as reference cahracteristic) into this and set the TOTAL Exception aggregation with reference characteristic Actual Delivery Date. Nested Exception Aggregation: If we need multiple exception aggregations or reference characteristics, we can nest formulas and calculated key figures in one another and specify an exception aggregation for each formula or calculated key figure. Necessity of Nested Exception Aggregation: As highlighted in the above screen shot, the results of the On-time deliveries, Deliveries Late and Deliveries early with the Actual Delivery Dates are X. If we create one level of exception aggregation with reference to Requested Delivery date then we get below result (Detail level): As per the result, the deliveries are not aggregated along with Actual Delivery Date ( X value in result columns). To avoid this situation we need one more level of Calculated Key Figures/Formula with Exception Aggreateion on current Calculated KeyFigures. 2011 SAP AG 17
Nested Exception Aggregation on On-time Deliveries CKF: Create New Calculate KeyFigure Deliveries On-Time (CKF_DEL_ON_TIME_3) and drag and drop the On- Time Del (CKF_ON_TIME_2) into the Detail View. Set the Exception Aggregation to Total and Actual Delivery date (0ACT_DL_DTE) as Reference Characteristic: 2011 SAP AG 18
Nested Exception Aggregation on Deliveries Late CKF: Similarly Create New Calculate KeyFigure for Late Deliveries (CKF_LATE_DEL_5) and drag and drop the Deliveries Late (CKF_DEL_LATE_4) into the Detail View. Set the Exception Aggregation to Total and Actual Delivery date (0ACT_DL_DTE) as Reference Characteristic 2011 SAP AG 19
Nested Exception Aggregation on Deliveries Early CKF: Create new Calculate KeyFigure Early Deliveries (CKF_EARLY_DEL_7) and drag and drop the Deliveries Early (CKF_DEL_LATE_4) CKF into the Detail View. Set the Exception Aggregation to Total and Actual Delivery date (0ACT_DL_DTE) as Reference Characteristic 2011 SAP AG 20
Drag and drop the Deliveries On-Time (CKF_DEL_ON_TIME_3), Late Deliveries (CKF_LATE_DEL_5) and Early Deliveries (CKF_EARLY_DEL_7) Calculated Key Figures into the Rows and Company code into the Coulumns. Report result (Summarized Level): 2011 SAP AG 21
