• What is the cause and solution for SAP error message WRF_AT001 - Enter an allocation table or at least one header criterion ?

  SAP Error Message:
  
  WRF_AT001 – Enter an allocation table or at least one header criterion
  
  Cause:
  This error occurs when you are trying to execute a function or transaction that requires either an allocation table or at least one header criterion to be specified, but neither has been provided. The system expects you to define how costs or values should be allocated (via an allocation table) or to specify criteria at the header level to guide the allocation or processing.
  Common scenarios where this error appears include:
  
  When working with cost allocation or settlement rules in controlling (CO) modules.
  When defining or running allocation cycles or distribution/assessment cycles.
  When using certain reporting or planning tools that require allocation parameters.
  
  
  Solution:
  To resolve the error:
  
  
  Enter an Allocation Table:
  
  Go to the relevant screen or transaction where the allocation table is to be specified.
  Provide a valid allocation table that defines how costs or values should be distributed.
  
  
  
  Or Enter at Least One Header Criterion:
  
  If you do not want to use an allocation table, specify at least one header criterion.
  Header criteria might include parameters such as cost center, profit center, order, or other controlling objects depending on the context.
  These criteria help the system identify the scope or filter for the allocation or processing.
  
  
  
  Check the Transaction or Program Documentation:
  
  Review the documentation or help for the specific transaction or report you are running to understand what allocation tables or header criteria are expected.
  
  
  
  Verify Master Data and Configuration:
  
  Ensure that allocation tables and header criteria are properly maintained in the system.
  Check if any customizing steps are missing in the controlling module or related areas.
  
  
  
  
  Related Information:
  
  
  Transactions/Modules:  
  
  CO (Controlling) module, especially cost center accounting, internal orders, and profit center accounting.  
  Allocation cycles (transaction codes like KSU1, KSU5, or similar).  
  Settlement rules and distribution/assessment cycles.
  
  
  
  SAP Notes and Documentation:  
  
  Check SAP Notes related to allocation and distribution errors if the problem persists.  
  SAP Help Portal for controlling allocation and settlement processes.
  
  
  
  Example:
  
  When running an assessment cycle, if you do not specify an allocation table or header criteria, the system cannot determine how to allocate costs, resulting in this error.
  
  
  
  If you provide the exact transaction or context where this error occurs, I can give more tailored guidance.
