• What is the cause and solution for SAP error message WSTRN015 - Define the allocation line either by assortment or by allocation rule ?

  SAP Error Message:
  
  WSTRN015 – Define the allocation line either by assortment or by allocation rule
  
  Cause:
  This error occurs in SAP's Trade Management or Trade Promotion Management modules when you try to create or process an allocation line without specifying the necessary allocation criteria. Specifically, the system requires that each allocation line be defined either by:
  
  An assortment (a predefined set of products or materials), or  
  An allocation rule (a rule that determines how quantities or values are allocated).
  
  If neither is specified, the system cannot determine how to allocate the quantities or values, hence it throws this error.
  
  Solution:
  To resolve the error WSTRN015, you need to:
  
  
  Check the allocation line details in your transaction (e.g., in promotion or trade agreement setup).  
  
  
  Specify either:
  
  An Assortment: Assign a valid assortment that groups the relevant products/materials for allocation.  
  An Allocation Rule: Assign a valid allocation rule that defines how the allocation should be distributed.
  
  
  
  Save the allocation line after entering the required field(s).
  
  
  
  Additional Information:
  
  This error is common in SAP Trade Promotion Management (TPM) or Trade Management when setting up promotions, rebates, or trade agreements that involve product allocations.  
  Assortments are used to group products logically for allocation purposes, while allocation rules define the logic or criteria for distributing quantities or values among products or customers.  
  Always ensure that your master data for assortments and allocation rules is properly maintained and active.  
  If you are unsure which allocation rule or assortment to use, consult your business process owner or SAP functional consultant responsible for trade management.
