This error typically occurs in the context of the SAP Materials Management (MM) module, particularly when dealing with purchase requisitions or purchase orders.
  Causes:

  Data Integrity Issues: The data being processed may have inconsistencies or may not meet the required criteria for insertion into the buffer table.
  Configuration Issues: There may be configuration settings in the MM module that are not correctly set up, leading to this error.
  Authorization Issues: The user may not have the necessary authorizations to perform the action that is trying to insert the item into the buffer table.

  System Performance: Monitor system performance and check for any issues that may be causing delays. If the system is under heavy load, consider scheduling the process during off-peak hours.
