• What is the cause and solution for SAP error message W5151 - All mandatory header data is missing ?

  SAP Error Message:
  
  W5151 - All mandatory header data is missing
  
  Cause:
  This warning message appears when you try to save or post a document (such as a purchase order, sales order, or delivery) in SAP, but the system detects that all mandatory header fields have not been filled in. The system requires certain key header data to process the document correctly, and if these fields are empty, it triggers this warning.
  Typical mandatory header fields might include:
  
  Document date
  Vendor/Customer
  Company code
  Purchasing organization
  Document type
  Sales area (sales org, distribution channel, division)
  Posting date
  
  If all these mandatory fields are missing or left blank, SAP issues the W5151 warning.
  
  Solution:
  
  
  Check and Enter Mandatory Header Data:
  
  Go back to the document header screen.
  Ensure that all mandatory fields are filled in correctly.
  Mandatory fields are usually marked with a check or asterisk or are defined by the document type configuration.
  
  
  
  Verify Document Type and Configuration:
  
  Sometimes, the document type configuration in IMG (Implementation Guide) defines which fields are mandatory.
  If you are customizing or using a custom document type, verify that the mandatory fields are correctly set up.
  
  
  
  Use F1 Help on Fields:
  
  Place the cursor on the field and press F1 to get detailed help about the field and whether it is mandatory.
  
  
  
  Check User Exits or Enhancements:
  
  If the system behavior is customized, check if any user exits or BAdIs are enforcing mandatory fields.
  Sometimes custom code might clear or not populate mandatory fields.
  
  
  
  Save After Entering Data:
  
  After entering all mandatory header data, try saving or posting the document again.
