• What is the cause and solution for SAP error message VH155 - Zero (0) is not a permitted item number ?

  SAP Error Message:
  
  VH155 - Zero (0) is not a permitted item number
  
  Cause:
  This error occurs when the system encounters an item number with the value zero (0) in a context where zero is not allowed. In SAP, item numbers typically start from 1 and increment by 1 for each item in a document (e.g., sales order, delivery, billing document). Zero is not a valid item number because it is reserved or considered invalid in the document structure.
  Common scenarios causing this error include:
  
  Custom code or user exits/enhancements incorrectly assigning item number 0.
  Data migration or interface programs passing item number 0.
  Manual entry or upload of documents with item number 0.
  Incorrect configuration or master data leading to zero item number assignment.
  
  
  Solution:
  
  
  Check the Source of the Item Number:
  
  Identify where the item number 0 is coming from (e.g., user input, interface, custom program).
  Review any custom code, user exits, BADIs, or enhancements that might be setting item number 0.
  
  
  
  Correct the Item Number Assignment:
  
  Ensure item numbers start from 1 and increment properly.
  Modify the code or data to assign valid item numbers.
  If the error occurs during data upload or interface processing, correct the source data.
  
  
  
  Data Validation:
  
  Implement validation checks to prevent zero item numbers from being processed.
  Use standard SAP validations or add custom validations if necessary.
  
  
  
  Reprocess the Document:
  
  After correcting the item numbers, reprocess the document or transaction.

  Transaction Codes to Check:  
  
  VA01/VA02 (Sales Order)  
  VL01N/VL02N (Delivery)  
  VF01/VF02 (Billing)  
  
  
  
  Debugging Tips:  
  
  Use transaction SE91 to look up message VH155 for more details.  
  Use debugging (SE80/SE38) to trace where item number 0 is assigned.  
  Check user exits like USEREXIT_MOVE_FIELD_TO_VBAP or BADIs related to item processing.
