How To Fix MC559 - Restriction has no effect on primary table (see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: MC - Aggregate: views, matchcodes, lock objects

• Message number: 559

• Message text: Restriction has no effect on primary table (see long text)

What causes this issue?

In a help view, you specified a selection condition for a field of a
secondary table.

System Response

The base tables of help views are linked with an "outer join".
This means that the entries of the primary table are displayed even if
there is no corresponding record in the secondary tables. Selection
conditions for the secondary table should be understoood in this
context. They do not cause records to be selected from the primary
table.
Selection conditions for secondary tables make sense if there is more
than one record of a secondary table for a record of the primary table
and the selection condition would ensure uniqueness.

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?

Check if the above-described behavior corresponds to what you wanted to
achieve with the selection condition.
