WZRE_PRX_MAPPING011 - Details

• Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_PRX_MAPPING011: BAdI &1 has multiple implementations
  
  
  Cause:
  This error occurs when the system expects a single implementation of a particular BAdI (Business Add-In), but it finds multiple active implementations instead.
  
  BAdIs are enhancement spots in SAP that allow custom code to be plugged in without modifying the standard SAP code.
  Some processes or function modules expect only one active implementation of a BAdI.
  If more than one implementation is active, the system cannot decide which one to execute, leading to this error.
  
  
  When does it typically occur?
  
  During runtime when the system tries to call a BAdI that is expected to have a unique implementation.
  Common in scenarios where the BAdI is defined as a single-use BAdI or when the code explicitly expects only one implementation.
  Often seen in workflow, proxy, or integration scenarios where BAdI implementations control specific logic.
  
  
  
  Solution:
  
  
  Check active BAdI implementations:
  
  Use transaction SE18 (BAdI Builder).
