• What is the cause and solution for SAP error message WG031 - Create pur. req. without supply source. Req. &, item & ?

  Certainly! Here's a detailed explanation for the SAP error message WG031:
  
  SAP Error Message: WG031
  Text: Create pur. req. without supply source. Req. &, item &
  
  Meaning / Cause:
  This error occurs when you try to create a Purchase Requisition (PR) without specifying a supply source, and the system settings require a supply source to be assigned.
  
  Supply source refers to a source of supply such as a contract, scheduling agreement, or info record that the system uses to determine where the material will be procured from.
  The system is configured to require a supply source for purchase requisitions, but none has been assigned for the material or item in question.
  This can happen if:
  
  The material master does not have a valid source list or info record.
  The source list is not maintained or is blocked.
  The system settings (in the material or plant parameters) require a supply source but none exists.
  The user tries to create a PR manually without specifying a source, and the system validation prevents it.
  
  
  
  
  When does it occur?
  
  During manual creation of purchase requisitions.
  When automatic creation of PRs (e.g., MRP run) tries to create PRs but no valid source of supply is found.
  When the system is set to enforce source determination strictly.
  
  
  Solution / How to fix:
  
  
  Check Source List:
  
  Use transaction ME01 to maintain the source list for the material and plant.
  Ensure that a valid source of supply (vendor, contract, scheduling agreement) is assigned and not blocked.
  If no source list exists, create one or maintain info records.
  
  
  
  Maintain Info Records:
  
  Use transaction ME11 to create or update purchasing info records for the material and vendor.
  Info records can act as a source of supply if source lists are not used.
  
  
  
  Check Material Master Settings:
  
  In the material master (MM02), check the Purchasing view.
  Verify if the material is set to require a source of supply.
  Check if the material is flagged for source list usage.
  
  
  
  Check Plant Parameters:
  
  In customizing (SPRO), check the settings for source determination.
  Path: Materials Management ? Purchasing ? Source Determination ? Set Up Source List
  Verify if the system is set to enforce source list usage strictly.
  
  
  
  Adjust System Settings (if appropriate):
  
  If business process allows, you can configure the system to allow PR creation without a source of supply.
  This is done in the material master or plant parameters by disabling the requirement for a source list.
  
  
  
  Manual Entry of Source:
  
  When creating the PR manually, specify the source of supply explicitly if the system requires it.
