• Message class: B1 - ALE group messages

• Message number: 809

• Message text: BAPI (&1, &2) is self-dependent

What causes this issue?

An error has been found in the assignment of the BAPI to the referenced
BAPI. The BAPI (&v1&, &v2&) has been defined as a dependent BAPI and as
a referenced BAPI.

System Response

This results in an endless dependendency for the receiver
determination.

• What is the cause and solution for SAP error message B1809 - BAPI (&1, &2) is self-dependent ?

  The SAP error message B1809 indicates that a BAPI (Business Application Programming Interface) is self-dependent, meaning that the BAPI is trying to call itself, which leads to a recursive situation that is not allowed. This typically occurs when a BAPI is designed in such a way that it inadvertently references itself, either directly or indirectly.
  
  Cause:
  
  Self-Referencing Logic: The BAPI may have been programmed to call itself as part of its processing logic.
  Incorrect Configuration: The BAPI might be incorrectly configured or designed, leading to unintended self-references.
  Circular Dependencies: There may be circular dependencies in the BAPI calls, where one BAPI calls another that eventually calls the first BAPI again.
  
  
  Solution:
  
  Review BAPI Logic: Check the implementation of the BAPI to ensure that it does not call itself. Look for any direct or indirect calls that may lead to recursion.
  Refactor Code: If the BAPI needs to perform similar operations, consider refactoring the code to separate the
