• What is the cause and solution for SAP error message CM_REPORT_TEMPLATE126 - Nesting error; more than one ELSE branch in a repeating grp not permitted ?

  The SAP error message CM_REPORT_TEMPLATE126 indicates that there is a nesting error in a report template, specifically related to the use of conditional branches (IF...ELSE) in a repeating group. This error occurs when there is more than one ELSE branch defined within a repeating group, which is not permitted in the report design.
  Cause:
  The primary cause of this error is the incorrect structure of the conditional logic in the report template. In a repeating group, you can have multiple IF conditions, but only one ELSE branch is allowed. If you attempt to define multiple ELSE branches, the system will throw this error.
  Solution:
  To resolve this error, you need to review the report template and adjust the conditional logic. Here are the steps you can take:
  
  
  Open the Report Template: Access the report template where the error is occurring.
  
  
  Identify the Repeating Group: Locate the repeating group that is causing the issue.
  
  
  Review Conditional Logic: Check the IF...ELSE statements within the repeating group. Ensure that there is only one ELSE branch defined.
  
  
  Consolidate ELSE Branches: If you find multiple ELSE branches, you will need to consolidate them. You can do this by:
  
  Merging the logic of the ELSE branches into a single ELSE statement.
  Using additional IF statements to handle different conditions instead of multiple ELSE branches.
  
  
  
  Test the Report: After making the necessary changes, save the report template and test it to ensure that the error is resolved and that the report behaves as expected.
  
  
  Related Information:
  
  Documentation: Refer to SAP documentation on report design and conditional logic for more detailed guidelines on structuring IF...ELSE statements.
  SAP Community: You can search for similar issues in the SAP Community forums, where other users may have encountered and resolved the same error.
  Debugging Tools: Utilize debugging tools within SAP to trace the execution of the report and identify where the nesting error occurs.
  
  By following these steps, you should be able to resolve the CM_REPORT_TEMPLATE126 error and ensure that your report template functions correctly.
