  The SAP error message DT246, which states "This number of key fields is not permitted with generic buffering," typically occurs when there is an attempt to use generic buffering on a database table that has too many key fields defined for it. Generic buffering is a performance optimization technique in SAP that allows for the caching of data in memory to reduce database access times. However, there are limitations on how many key fields can be used with this method.
  
  Cause:
  The error is caused by the following:
  
  Too Many Key Fields: The table in question has more key fields than what is allowed for generic buffering. SAP has a limit on the number of key fields that can be used for generic buffering, which is typically 1 or 2 key fields.
  Buffering Configuration: The buffering settings for the table may have been incorrectly configured, leading to an attempt to use generic buffering on
