  The SAP error message 1BKKBAPI020 indicates that there is a problem with a Business Add-In (BAdI) implementation in your SAP system. Specifically, it states that a single-use BAdI has multiple implementation classes, which is not allowed. Here’s a breakdown of the cause, potential solutions, and related information:
  
  Cause:
  
  Multiple Implementations: The error occurs when there are multiple active implementations of a single-use BAdI. Single-use BAdIs are designed to allow only one implementation at a time, and having more than one leads to ambiguity in which implementation should be executed.
  
  Configuration Issues: There may be a configuration issue where the system is not correctly recognizing the active implementation.
  Transport Issues: If BAdI implementations were transported from one system to another (e.g., from development to production), it could lead to inconsistencies.
