  Cause
  This error occurs when a purchasing document or transaction requires a purchasing group to be specified, but the field is either left blank or the system cannot find a valid purchasing group assigned to the relevant data.
  Common scenarios include:
  
  Creating or changing a purchase requisition, purchase order, or contract without specifying a purchasing group.
  The purchasing group field is not maintained in the master data or customizing.
  The system expects a purchasing group based on configuration or business rules, but none is provided.

  Explanation
  The Purchasing Group is a key organizational unit in SAP MM (Materials Management) responsible for procurement activities. It represents a buyer or a group of buyers who handle purchasing for certain materials or services.
  If the purchasing group is missing, SAP cannot determine who is responsible for the procurement process, which is essential for workflow, approvals, and reporting.
