• What is the cause and solution for SAP error message WSTRN090 - You cannot delete Prepack &1; it is used in the allocation plan ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WSTRN090 - You cannot delete Prepack &1; it is used in the allocation plan
  
  Cause:
  This error occurs when you try to delete a Prepack (a predefined package or assortment of products) that is currently referenced or used in an allocation plan. Allocation plans are used in SAP to manage and distribute stock or products to various locations or customers based on predefined rules.
  Since the Prepack is linked to an active allocation plan, SAP prevents its deletion to maintain data consistency and avoid breaking references in the allocation process.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify the Allocation Plan(s) Using the Prepack:
  
  Check which allocation plan(s) reference the Prepack you want to delete.
  You can do this by reviewing allocation plans in transaction codes like /SAPAPO/ATP, /SAPAPO/SDP94, or relevant allocation plan maintenance transactions depending on your SAP module.
  
  
  
  Remove or Change the Reference:
  
  Either delete the Prepack from the allocation plan or replace it with another valid Prepack or product.
  Save the changes to the allocation plan.
  
  
  
  Delete the Prepack:
  
  Once the Prepack is no longer referenced in any allocation plan, you can proceed to delete it without encountering the error.
  
  
  
  Additional Checks:
  
  Ensure that the Prepack is not used in other dependent objects like sales orders, deliveries, or planning objects.
  If it is, those references must be cleared or adjusted accordingly.
  
  
  
  
  Related Information:
