• What is the cause and solution for SAP error message MW387 - Allocation stategy &1: no allocation strategy function module exists ?

  The SAP error message MW387 indicates that there is an issue with the allocation strategy in the system. Specifically, it means that the allocation strategy you are trying to use does not have a corresponding function module defined in the system. This can occur in various contexts, such as during the allocation of stock or during the planning processes.
  Cause:
  
  Missing Function Module: The allocation strategy you are trying to use is not properly configured, and the required function module for that strategy does not exist in the system.
  Incorrect Configuration: The allocation strategy may not be correctly set up in the configuration settings, leading to the system being unable to find the necessary function module.
