• What is the cause and solution for SAP error message DT756 - Sharing is only allowed for transparent tables. ?

  The SAP error message DT756 ("Sharing is only allowed for transparent tables") typically occurs when you attempt to create or modify a database table in a way that is not compatible with the sharing of data between different database tables. This error is specifically related to the types of tables in the SAP data dictionary.
  Cause:
  
  Table Type: The error arises when you try to share a non-transparent table (like pooled or cluster tables) with other tables. In SAP, only transparent tables can be shared across different database tables.
  Data Dictionary Configuration: If you are trying to create a view or a table that references a non-transparent table, this error will be triggered.
  Incorrect Table Definition: The definition of the table might not align with the requirements for sharing, such as using a non-transparent table type.
  
  Solution:
  
  Use Transparent Tables: Ensure that the tables you are trying to share are transparent tables. If you need to share data, consider redesigning your database schema to use transparent tables.
  Check Table Definitions: Review the definitions of the tables involved. If you are working with a pooled or cluster table, you may need to convert it to a transparent table if sharing is required.
  Adjust Data Model: If your data model requires sharing, you may need to adjust it to ensure that only transparent tables are used for shared data.
  Consult Documentation: Refer to SAP documentation or the ABAP Dictionary to understand the differences between table types and the implications of using them.
