• What is the cause and solution for SAP error message CNIF_STATUS012 - Error calling up BAPI: WBS Element &1 appears more than once ?

  The SAP error message CNIF_STATUS012 indicates that there is an issue with a Work Breakdown Structure (WBS) element being referenced multiple times in a context where it should only appear once. This typically occurs when you are trying to create or update a project or a related object using a BAPI (Business Application Programming Interface) and the system detects duplicate entries for the specified WBS element.
  Cause:
  
  Duplicate WBS Elements: The most common cause of this error is that the same WBS element is being passed multiple times in the input data to the BAPI.
  Incorrect Data Structure: The data structure being used to call the BAPI may not be correctly defined, leading to the same WBS element being included multiple times.
  Data Integrity Issues: There may be issues with the data integrity in the project structure, where the same WBS element is inadvertently linked or referenced multiple times.
  
  Solution:
  
  Check Input Data: Review the input data being passed to the BAPI. Ensure that each WBS element is unique and is not being included more than once.
  Debugging: If you have access to the ABAP debugger, you can step through the BAPI call to see how the data is being processed and identify where the duplication is occurring.
  Data Structure Review: Ensure that the data structure (like internal tables) used to pass WBS elements to the BAPI is correctly defined and populated.
  Data Cleanup: If there are actual duplicates in the project structure, you may need to clean up the data by removing or consolidating duplicate WBS elements.
  Consult Documentation: Refer to the SAP documentation for the specific BAPI you are using to understand the expected input format and constraints.
  
  Related Information:
  
  BAPI Documentation: Check the SAP Help Portal or the specific BAPI documentation for details on the expected input parameters and any constraints related to WBS elements.
