• What is the cause and solution for SAP error message SMTTOOLS105 - &: Views with sharingtype T can only have one base table ?

  The SAP error message SMTTOOLS105, which states "Views with sharing type T can only have one base table," typically occurs in the context of SAP HANA or when working with SAP's Smart Data Integration (SDI) or Smart Data Access (SDA). This error indicates that you are trying to create or modify a view that is defined with a sharing type of "T" (which stands for "table") but is referencing multiple base tables.
  Cause:
  The error arises because:
  
  Sharing Type T: Views with sharing type T are designed to work with a single base table. This is a restriction in the way that these views are defined and managed within the SAP system.
  Multiple Base Tables: If your view definition includes joins or references to multiple tables, it violates the requirement for sharing type T.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the View Definition: Check the SQL or graphical definition of the view to identify how many base tables are being referenced. Ensure that only one base table is included.
  
  
  Change the Sharing Type: If your use case requires multiple tables, consider changing the sharing type of the view. You may need to use a different type of view that allows for multiple base tables, such as a view with a different sharing type (e.g., "V" for view).
  
  
  Create Separate Views: If you need to work with multiple tables, consider creating separate views for each base table and then combining the results in your application logic or through another view that can handle multiple tables.
  
  
  Use Joins in a Different Context: If you need to join multiple tables, consider creating a new view that uses a different sharing type or a database procedure that can handle the logic you need.
