How To Fix DD_MT_SHARING098 - Table &1: Sharing type W not allowed (non-key fields in namespace def.)

SAP Error Message - Details

• Message type: E = Error

• Message class: DD_MT_SHARING - DDIC Multi Tenancy Sharing: Messages

• Message number: 098

• Message text: Table &1: Sharing type W not allowed (non-key fields in namespace def.)

What causes this issue?

The table has a customer namespace definition. Customer namespace
definitions separates customer content from SAP content, are maintained
along with the delivery class and are stored in table TRESC.
For the present table, the customer namespace definition is based on
non-key fields.
Sharing type W requires a where condition for the tenant separation,
which has to be aligned with the customer namespace definition. But
non-key fields can currently not be used for the where condition for the
tenant separation.
So sharing type W is not allowed this table.

• What is the cause and solution for SAP error message DD_MT_SHARING098 - Table &1: Sharing type W not allowed (non-key fields in namespace def.) ?

  The SAP error message DD_MT_SHARING098 indicates that there is an issue with the sharing type of a table in the Data Dictionary. Specifically, the error message states that sharing type W (which stands for "with non-key fields") is not allowed for the specified table because it contains non-key fields in the namespace definition.
  Cause:
  The error occurs when you attempt to define a table with sharing type W while it has non-key fields that are not allowed in that context. Sharing type W is typically used for tables that are intended to be shared across different applications or modules, but it has restrictions regarding the fields that can be included.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Definition: Review the definition of the table in question (denoted as &1 in the error message). Look for non-key fields that may be causing the issue.
  
  
  Change Sharing Type: If the table contains non-key fields and you want to keep them, consider changing the sharing type from W to another type that allows non-key fields, such as N (non-shared) or S (shared with key fields only).
  
  
  Remove Non-Key Fields: If the non-key fields are not necessary for the table's purpose, you can remove them from the table definition to comply with the sharing type W.
  
  
  Consult Documentation: Refer to SAP documentation or the Data Dictionary guidelines for more information on sharing types and their restrictions.
  
  
  Transport Request: If you are making changes in a development environment, ensure that you transport the changes to the appropriate environment (e.g., quality assurance or production) after testing.
