• What is the cause and solution for SAP error message W_CB118 - Enter a purchasing group ?

  SAP Error Message:
  
  W_CB118 - Enter a purchasing group
  
  Cause:
  This warning message appears when you are creating or changing a purchasing document (such as a purchase requisition, purchase order, or contract) and the Purchasing Group field is left empty or not entered. The purchasing group is a mandatory field in many SAP procurement transactions because it identifies the group or individual responsible for the purchasing activity.
  
  Explanation:
  
  Purchasing Group is a key organizational unit in SAP MM (Materials Management) that represents a buyer or a group of buyers.
  It is used for reporting, workflow, and authorization purposes.
  If this field is missing, SAP cannot properly assign responsibility or route the document for approval.
  
  
  Solution:
  
  Enter a valid Purchasing Group in the relevant field on the purchasing document screen.
  The purchasing group must be defined in the system (transaction code OMSG or SPRO ? Materials Management ? Purchasing ? Maintain Purchasing Groups).
  If you do not know the correct purchasing group, consult your purchasing department or SAP MM team.
  After entering the purchasing group, save the document again.
  
  
  Additional Information:
  
  The purchasing group is different from the purchasing organization; the organization is responsible for procurement strategy, while the group is responsible for execution.
  If the purchasing group field is not mandatory in your business process, the warning message can be configured or suppressed via customizing, but this is generally not recommended.
  You can check or maintain purchasing groups via transaction OMSG.
  In some cases, the purchasing group can be defaulted based on material master data or vendor master data if configured.
