• What is the cause and solution for SAP error message DD_MT_SHARING_CHK023 - View requires sharing type T as base table is of sharing type T or S ?

  The SAP error message DD_MT_SHARING_CHK023 indicates that there is an issue with the sharing type of a view in relation to its base table. Specifically, this error occurs when a view is defined in such a way that it requires a sharing type of "T" (which stands for "Transparent") but the base table it references is of sharing type "T" or "S" (which stands for "Shared"). 
  Cause:
  
  Sharing Type Mismatch: The view is trying to access a base table that has a different sharing type than what is required. In this case, the view expects a base table with sharing type "T" but is encountering a base table that is either "T" or "S".
  View Definition: The view might be incorrectly defined, or the base table might have been changed after the view was created, leading to this inconsistency.
  
  Solution:
  
  Check View Definition: Review the definition of the view to ensure that it is correctly set up to reference the appropriate base tables. Make sure that the sharing type aligns with the base table's sharing type.
  Adjust Base Table: If possible, consider changing the sharing type of the base table to match the requirements of the view. However, this may not always be feasible depending on the system design and requirements.
  Recreate the View: If the view is not correctly defined, you may need to drop and recreate the view with the correct parameters that align with the base table's sharing type.
  Consult Documentation: Refer to SAP documentation or consult with your SAP Basis or ABAP team to understand the implications of changing sharing types and to ensure that any changes made do not affect other parts of the system.
