How To Fix SDDL_PARSER_MSG127 - Association &2 is not required for selection of the element &1

SAP Error Message - Details

• Message type: E = Error

• Message class: SDDL_PARSER_MSG - Message Class for DDL Parser

• Message number: 127

• Message text: Association &2 is not required for selection of the element &1

What causes this issue?

The association &V2& is not necessary for the selection of the attribute
&V1& because ? due to the underlying On clause ? the value is already
contained in &V3& (attribute: &V4&). Using the association &V2& at this
point results in a LEFT OUTER JOIN in the database view.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Instead of the association &V2&, the attribute &V4& should be read
directly from the underlying data source (table or view).
