VBDRV026 - Details

• 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.
