• What is the cause and solution for SAP error message DT664 - Technical settings not meaningful for tables of type & ?

  The SAP error message DT664 indicates that there is an issue with the technical settings of a database table in the Data Dictionary (DDIC). Specifically, it suggests that the technical settings defined for a table of a certain type are not appropriate or meaningful. This error typically arises when the table type does not support the specified technical settings.
  Cause:
  The error can occur for several reasons, including:
  
  Incorrect Table Type: The table type may not support certain technical settings. For example, a table defined as a "pool" or "cluster" table may not allow certain settings that are valid for transparent tables.
  Inconsistent Settings: The technical settings defined for the table may be inconsistent with the type of table it is. For instance, specifying settings that are only applicable to transparent tables for a pooled or cluster table.
  Missing or Incorrect Configuration: The technical settings may not be configured correctly, leading to this error.
  
  Solution:
  To resolve the DT664 error, you can follow these steps:
  
  
  Check Table Type: Verify the type of the table in question. You can do this by navigating to the Data Dictionary (transaction SE11) and checking the table's properties.
  
  
  Review Technical Settings: Go to the technical settings of the table (in SE11, select the table and click on "Technical Settings"). Ensure that the settings are appropriate for the table type. For example:
  
  For transparent tables, ensure that the settings like data class, size category, and buffering are correctly defined.
  For pooled or cluster tables, ensure that you are not trying to apply settings that are not applicable.
  
  
  
  Adjust Settings: If you find that the settings are incorrect, adjust them to be appropriate for the table type. You may need to remove or change settings that are not meaningful for the specific table type.
  
  
  Activate the Table: After making the necessary changes, activate the table again. This can be done in SE11 by clicking on the "Activate" button.
  
  
  Check for Dependencies: If the table is part of a larger application or has dependencies, ensure that any changes made do not affect other components.
