• What is the cause and solution for SAP error message MMPUR_CAT_EXTR_LGMSG122 - Buffer is Full ?

  The SAP error message MMPUR_CAT_EXTR_LGMSG122: Buffer is Full typically occurs in the context of the SAP Materials Management (MM) module, particularly when dealing with the purchase requisition or purchase order processes. This error indicates that the internal buffer used for processing data has reached its limit, which can prevent further data from being processed or displayed.
  Causes:
  
  Data Volume: The error often arises when there is a large volume of data being processed, such as a high number of line items in a purchase requisition or order.
  System Configuration: The buffer size may be set too low in the system configuration, leading to overflow when processing large datasets.
  Inefficient Queries: Inefficient or poorly optimized queries that retrieve large amounts of data can also contribute to this issue.
  Temporary Data: Accumulation of temporary data in the buffer that is not being cleared properly.
  
  Solutions:
  
  
  Increase Buffer Size: 
  
  Consult with your SAP Basis team to increase the buffer size settings in the system configuration. This may involve adjusting parameters in the SAP kernel or database settings.
