• What is the cause and solution for SAP error message WSTRN009 - Assortment &1 is already in your allocation plan ?

  SAP Error Message:
  
  WSTRN009 Assortment &1 is already in your allocation plan
  
  Cause:
  This error occurs when you try to add an assortment (a predefined group of products or materials) to an allocation plan, but the same assortment is already included in that allocation plan. Essentially, the system prevents duplicate entries of the same assortment within a single allocation plan.
  
  Explanation:
  
  Assortment: A collection or group of products/materials defined for planning or allocation purposes.
  Allocation Plan: A plan used in SAP to allocate quantities of products to different sales channels, customers, or regions.
  When you attempt to add an assortment that is already part of the allocation plan, SAP throws this error to avoid redundancy and potential conflicts in allocation.
  
  
  Solution:
  
  
  Check Existing Assortments in the Allocation Plan:
  
  Review the allocation plan to see which assortments are already assigned.
  Use transaction codes related to allocation planning (e.g., /SAPAPO/ATP, /SAPAPO/SDP94, or the relevant planning transaction in your SAP system).
  
  
  
  Avoid Duplicate Entry:
  
  If the assortment is already present, do not add it again.
  Instead, modify the existing assortment entry if changes are needed.
  
  
  
  Remove or Replace Assortment:
  
  If you intended to replace the assortment, first remove the existing one from the allocation plan before adding a new one.
  
  
  
  Check for User or System Errors:
  
  Sometimes, the error might be caused by a misunderstanding of the allocation plan structure or a system glitch.
  Verify with your planning team or SAP support if unsure.
