• What is the cause and solution for SAP error message PLMDISCALC016 - Recursions where header and item are identical ?

  The SAP error message PLMDISCALC016 indicates that there is a recursion issue in the calculation of a planning scenario where the header and item are identical. This typically occurs in the context of planning and forecasting in SAP, particularly when using the SAP Integrated Business Planning (IBP) or SAP Advanced Planning and Optimization (APO) modules.
  Cause:
  The error arises when the system detects that the same planning object (header) is being referenced in a way that creates a circular reference or recursion. This can happen in various scenarios, such as:
  
  Identical Header and Item: The planning item is set up in such a way that it refers back to itself, causing an infinite loop in calculations.
  Incorrect Configuration: The planning configuration may not be set up correctly, leading to unintended references.
  Data Issues: There may be issues with the data being used in the planning process, such as incorrect master data or planning levels.
  
  Solution:
  To resolve the PLMDISCALC016 error, you can take the following steps:
  
  
  Check Planning Levels: Review the planning levels and ensure that the header and item are not set to the same level in a way that causes recursion.
  
  
  Review Calculation Logic: Examine the calculation logic or formulas used in the planning scenario. Ensure that they do not reference the same object in a way that creates a loop.
  
  
  Adjust Data: If the issue is related to specific data, check the master data and transactional data for inconsistencies or errors that might be causing the recursion.
  
  
  Modify Planning Object: If necessary, modify the planning object structure to avoid identical references. This may involve changing how the header and item are defined or how they interact.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to PLMDISCALC016 for any specific guidelines or updates that may address this issue.
  
  
  Testing: After making changes, test the planning scenario to ensure that the error no longer occurs and that calculations are performed correctly.

  Documentation: Review the official SAP documentation for the specific planning module you are using (IBP, APO, etc.) for best practices and configuration guidelines.
  
  By following these steps, you should be able to identify the cause of the recursion and implement a solution to resolve the PLMDISCALC016 error.
