• What is the cause and solution for SAP error message WS623 - No data found in internal table T_KOMLFK (internal error) ?

  SAP Error Message:
  
  WS623 No data found in internal table T_KOMLFK (internal error)
  
  Cause
  The error WS623 typically occurs during pricing or condition record processing in SAP SD (Sales and Distribution) or MM (Materials Management) modules. The message indicates that the system expected to find data in the internal table T_KOMLFK but found none. This internal table usually holds condition records or pricing data relevant to the current transaction.
  Common causes include:
  
  Missing or incomplete condition records for the pricing procedure in use.
  Incorrect or incomplete configuration of pricing procedures.
  Inconsistent or corrupted condition tables or access sequences.
  Custom code or user exits/enhancements that manipulate pricing data incorrectly.
  Data inconsistencies or missing master data (e.g., customer, material, or condition master data).
  Issues during pricing determination where the system cannot find any valid condition records to apply.
  
  
  Solution
  To resolve the WS623 error, consider the following steps:
  
  
  Check Condition Records:
  
  Verify that condition records exist for the relevant condition types in the pricing procedure.
  Use transaction VK13 to display condition records and ensure they are maintained correctly.
  
  
  
  Review Pricing Procedure:
  
  Check the pricing procedure assigned to the sales document type and customer pricing procedure.
  Ensure all condition types in the pricing procedure are correctly configured and active.
  
  
  
  Analyze Access Sequences:
  
  Verify that access sequences linked to condition types are correctly set up and that the condition tables contain valid data.
  Use transaction V/07 to review access sequences.
  
  
  
  Check Master Data:
  
  Ensure that customer master, material master, and other relevant master data are complete and consistent.
  Missing or incorrect data can cause pricing determination to fail.
  
  
  
  Debug Pricing:
  
  Use transaction VA02 or the relevant transaction and activate debugging to trace pricing determination.
  Check where the internal table T_KOMLFK is expected to be filled and why it is empty.
  
  
  
  Review User Exits / Enhancements:
  
  If custom code is implemented in pricing user exits (e.g., USEREXIT_PRICING_PREPARE_TKOMK), check for errors or logic that might clear or fail to populate T_KOMLFK.
  
  
  
  SAP Notes and Support:
  
  Search for SAP Notes related to WS623 and T_KOMLFK for any known bugs or patches.
  If the problem persists, consider raising a support ticket with SAP, providing detailed logs and debugging information.
