• What is the cause and solution for SAP error message WSTRN100 - Select an allocation rule first ?

  SAP Error Message:
  
  WSTRN100 Select an allocation rule first
  
  Cause:
  This error occurs when you attempt to perform a settlement or allocation process in SAP without first specifying or selecting an allocation rule. Allocation rules define how costs or revenues are distributed from sender objects (like cost centers, orders, projects) to receiver objects during settlement.
  In other words, the system requires an allocation rule to know how to allocate costs, and if none is selected, it throws this error.
  
  When does it typically occur?
  
  During settlement runs (e.g., in CO-PA, Internal Orders, WBS elements).
  When using transaction codes related to settlement (e.g., KO88, CJ88, KSU5).
  When executing allocation cycles or cost distribution processes without specifying the allocation rule.
  
  
  Solution:
  
  
  Select or Maintain an Allocation Rule:
  
  Before running the settlement, ensure that an allocation rule is assigned to the sender object.
  For example, in Internal Orders, check the settlement rule in the order master data (KO02 ? Settlement rule tab).
  For WBS elements, check the settlement rule in the project system.
  
  
  
  Create or Assign an Allocation Rule if Missing:
  
  If no allocation rule exists, create one via the appropriate customizing path or master data maintenance.
  For Internal Orders: Assign settlement receivers and allocation rules in the settlement rule.
  For other objects, ensure the allocation rule is properly maintained.
  
  
  
  Check the Settlement Profile:
  
  The settlement profile controls the settlement process and may require an allocation rule.
  Verify that the settlement profile is correctly assigned and configured.
  
  
  
  During Execution:
  
  When prompted by the system, explicitly select the allocation rule before proceeding.
  In some cases, the system may allow multiple allocation rules; select the correct one.

  Transaction Codes:
  
  KO88 – Settlement of Internal Orders
  CJ88 – Settlement of WBS Elements
  KSU5 – Execute Assessment Cycle
  KSV5 – Execute Distribution Cycle
  
  
  
  Master Data:
  
  Internal Order Settlement Rule (in order master data)
  WBS Element Settlement Rule
  Allocation Rules (customizing or master data)
  
  
  
  Customizing Path:
  
  For Internal Orders:
  
  SPRO ? Controlling ? Internal Orders ? Settle Internal Orders ? Define Settlement Profiles
  For WBS Elements:
  
  SPRO ? Project System ? Costs ? Settlement ? Define Settlement Profiles
  
  
  
  Notes:
  
  Always ensure that the allocation rule is active and valid for the period.
  If multiple allocation rules exist, confirm the correct one is selected.
  Check user authorizations if the allocation rule cannot be selected.
  
  
  
  
  Summary:
  The error WSTRN100 Select an allocation rule first means the system requires you to specify an allocation rule before proceeding with settlement or allocation. To fix it, assign or select the appropriate allocation rule in the sender object's master data or during the settlement process.
