  Error Message
  W5128: Please group together only requisitions with same requester '&'
  
  Cause
  This warning message occurs in SAP Materials Management (MM) during the purchase requisition grouping process, typically when you try to create a purchase order (PO) by grouping multiple purchase requisitions (PRs).
  
  Reason: SAP requires that all purchase requisitions grouped together to create a single purchase order must have the same requester (the person who created the requisitions).
  If you attempt to group PRs with different requesters, the system issues this warning to prevent mixing requisitions from different requesters in one PO.
  
  
  Explanation
  
  The requester is a field in the purchase requisition that identifies the person or department requesting the goods or services.
  Grouping PRs with different requesters can cause issues in approval workflows, accountability, and communication.
  SAP enforces this rule to maintain clarity and proper tracking of purchase requisitions.
  
  
  Solution / How to Resolve
  
  
  Group PRs by Requester:
  
  When creating a purchase order from multiple purchase requisitions, ensure that you only select PRs with the same requester.
  You can filter or sort the PR list by requester to group them accordingly.
  
  
  
  Create Separate Purchase Orders:
  
  If you have PRs from different requesters, create separate purchase orders for each requester group.
  
  
  
  Check Requester Field:
  
  Verify the requester field in each purchase requisition to confirm who created it.
  You can display the PR and check the "Requester" field in the header data.
  
  
  
  Adjust Business Process (if needed):
  
  If your business process requires grouping PRs from different requesters, you may need to review and adjust your process or consult with your SAP MM consultant.
  However, standard SAP behavior enforces this restriction for good reason.

  Transaction Codes:
  
  ME51N: Create Purchase Requisition
  ME21N: Create Purchase Order

  Customization:
  
  The grouping criteria can be influenced by configuration in the IMG under Materials Management ? Purchasing ? Purchase Requisition ? Define Grouping Criteria.
  However, the requester field is a standard grouping criterion and usually cannot be bypassed.
