• What is the cause and solution for SAP error message WA751 - Table buffer synchronized ?

  SAP Error Message:
  
  WA751 - Table buffer synchronized
  
  Cause:
  The message WA751 Table buffer synchronized occurs when the SAP system detects that the buffer for a particular table has been synchronized or refreshed. This typically happens in environments where table buffering is active, and the system needs to ensure that the buffer contains the most recent data.
  More specifically, this message is often triggered when:
  
  The table buffer has been updated or invalidated due to changes in the underlying database table.
  Another user or process has changed the data, causing the buffer to be refreshed.
  The system is ensuring data consistency by synchronizing the buffer with the database.
  
  This message is informational and indicates that the system has synchronized the buffer to maintain data integrity.
  
  Solution:
  Since WA751 is an informational message rather than an error, it usually does not require corrective action. However, if this message appears frequently and impacts performance or user experience, consider the following:
  
  
  Review Table Buffering Settings:
  
  Check if the table buffering is necessary for the table in question.
  Buffering can be set to single-record, generic, or full buffering.
  Adjust buffering settings in transaction SE11 (Data Dictionary) if needed.
  
  
  
  Analyze Buffer Synchronization Frequency:
  
  Frequent synchronization may indicate high update activity on the buffered table.
  If updates are frequent, buffering might not be beneficial and could be disabled.
  
  
  
  Check for Custom Code or Batch Jobs:
  
  Identify if any custom programs or batch jobs are updating the table frequently.
  Optimize or reschedule these jobs to reduce buffer invalidations.
  
  
  
  System Performance Tuning:
  
  Ensure that the SAP system and database are properly tuned to handle buffering efficiently.
  
  
  
  
  Related Information:
  
  
  Table Buffering in SAP:
  
  Table buffering improves performance by caching table data in the application server memory.
  It reduces database access but requires synchronization to maintain data consistency.
  Buffer synchronization messages like WA751 are part of this mechanism.
  
  
  
  Transaction SE11:
  
  Used to view and change table buffering settings.
  Buffering options:
  
  No buffering
  Single-record buffering
  Generic buffering
  Full buffering
  
  
  
  
  
  Transaction ST02:
  
  Monitor buffer quality and usage statistics.
  
  
  
  SAP Notes:
  
  Check SAP Notes for any known issues related to table buffering and WA751 messages.
  
  
  
  
  Summary:
  
  WA751 is an informational message indicating that the table buffer has been synchronized.
  It is caused by updates to buffered tables requiring buffer refresh.
  Usually, no action is needed unless performance is impacted.
  Review and optimize table buffering settings and update frequency if necessary.
