• What is the cause and solution for SAP error message MMPUR_RPO_MESSAGES018 - Only one purchase order could be processed ?

  The SAP error message MMPUR_RPO_MESSAGES018 ("Only one purchase order could be processed") typically occurs in the context of the SAP Materials Management (MM) module, particularly when dealing with purchase requisitions or purchase orders. This error indicates that the system is expecting to process multiple purchase orders, but it can only handle one at a time due to certain constraints or settings.
  Causes:
  
  Single Purchase Order Requirement: The transaction or function you are trying to execute may be designed to handle only one purchase order at a time. This is common in certain transaction codes or reports.
  Selection Criteria: If you are using a selection screen to process multiple purchase orders, the criteria may be set in such a way that only one purchase order meets the conditions.
  System Configuration: There may be configuration settings in the SAP system that restrict the processing of multiple purchase orders simultaneously.
  User Authorization: The user may not have the necessary authorizations to process multiple purchase orders, leading to the system limiting the action to one.
  
  Solutions:
  
  Check Selection Criteria: Review the selection criteria you are using to ensure that you are not inadvertently filtering down to a single purchase order. Adjust the criteria if necessary to include multiple purchase orders.
  Process One Purchase Order at a Time: If the transaction is designed to handle only one purchase order, you may need to process each purchase order individually.
  Review Configuration Settings: Consult with your SAP administrator or functional consultant to review the configuration settings related to purchase order processing. They may need to adjust settings to allow for multiple purchase orders to be processed.
  User Authorization: Ensure that you have the appropriate authorizations to process multiple purchase orders. If not, contact your system administrator to request the necessary permissions.
