• What is the cause and solution for SAP error message VBDRV026 - Derivation terminated: return code in customer function ?

  The SAP error message VBDRV026 indicates that there was an issue during the derivation process in the SAP system, specifically related to a customer function. This error typically occurs in the context of the SAP Sales and Distribution (SD) module, particularly when dealing with pricing or condition records.
  Cause:
  The error message "Derivation terminated: return code in customer function" suggests that a custom function module or routine that is supposed to derive certain values (like pricing conditions) has returned an unexpected return code. This can happen due to several reasons:
  
  Coding Errors: There may be a bug or logical error in the custom function code that prevents it from executing correctly.
  Data Issues: The data being processed may not meet the expected criteria, leading to an error in the derivation logic.
  Configuration Issues: The configuration settings for the pricing procedure or condition types may not be set up correctly, causing the derivation to fail.
  Missing Authorizations: The user executing the transaction may not have the necessary authorizations to access certain data or execute specific functions.
  
  Solution:
  To resolve the VBDRV026 error, you can follow these steps:
  
  
  Check the Custom Function: 
  
  Review the custom function module or routine that is being called during the derivation process. Look for any coding errors or unexpected return codes.
  Ensure that the function is designed to handle all possible input scenarios correctly.
  
  
  
  Debugging:
  
  Use the SAP debugger to step through the execution of the function to identify where it is failing and why it is returning an error code.
  Check the input parameters being passed to the function to ensure they are valid.
  
  
  
  Review Configuration:
  
  Verify the configuration settings for the pricing procedure and condition types in the SAP system. Ensure that all necessary settings are correctly defined.
  Check if any recent changes were made to the configuration that could have affected the derivation process.
  
  
  
  Data Validation:
  
  Ensure that the data being processed (e.g., customer master data, material master data, etc.) is complete and accurate.
  Look for any inconsistencies or missing data that could lead to the derivation failure.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the transaction has the necessary authorizations to access the required data and execute the function.
  
  
  
  Consult Documentation:
  
  Review any documentation related to the custom function or the pricing procedure to ensure that it is being used correctly.
