• What is the cause and solution for SAP error message AD422 - Table & cannot be buffered ?

  The SAP error message AD422 indicates that a specific table cannot be buffered. This typically occurs when you attempt to set a table for buffering in the SAP system, but the system has determined that the table does not meet the criteria for buffering. 
  Causes of Error AD422
  
  
  Table Characteristics: The table may have certain characteristics that prevent it from being buffered. For example:
  
  The table is a transparent table that has a primary key that is not unique.
  The table is a pooled or cluster table.
  The table is defined with certain data types or structures that are incompatible with buffering.
  
  
  
  Database Constraints: The underlying database may impose constraints that prevent the table from being buffered.
  
  
  Technical Settings: The technical settings of the table in the Data Dictionary (SE11) may not allow buffering. This can include settings related to the buffering type (e.g., "No buffering" or "Buffering not allowed").
  
  
  Solutions to Error AD422
  
  
  Check Table Definition: 
  
  Go to transaction SE11 and check the technical settings of the table. Ensure that the buffering option is set correctly and that the table meets the requirements for buffering.

  If the table is not required to be buffered, you can leave it as is. If buffering is necessary, consider modifying the table structure or characteristics to make it eligible for buffering.
