  The SAP error message QS187 ("Changes cannot be distributed using ALE") typically occurs in the context of Application Link Enabling (ALE) when there are issues related to the distribution of changes in the system. This error is often encountered in scenarios involving master data or configuration data that is intended to be distributed across different systems.
  Cause:
  The error can be caused by several factors, including:
  
  
  Incompatible Data Objects: The data object you are trying to distribute may not be configured for ALE distribution. Some data types or objects are not supported for distribution.
  
  
  Missing Configuration: The ALE configuration for the specific data object may not be set up correctly. This includes settings in the Distribution Model (BD64) or the necessary message types.
  
  
  Change Document Not Created: If the change document for the object is not created or is not available, the system will not allow the distribution of changes.
  
  
  Incorrect Partner Profile: The partner profile (WE20) may not be set up correctly for the receiving system, which can prevent the distribution of changes.
  
  
  Authorization Issues: There may be authorization issues preventing the user from executing the distribution.
  
  
  Solution:
