How To Fix SRF_AUTHORING238 - Loop query &1 does not use all non-unique key fields

SAP Error Message - Details

• Message type: E = Error

• Message class: SRF_AUTHORING - Message class for SRF Authoring

• Message number: 238

• Message text: Loop query &1 does not use all non-unique key fields

What causes this issue?

You defined a loop query which does not use all non-unique key fields
(neither from primary key or nor from secondary keys by means of unique
table indexes). Non-unique key fields are those key fields whose values
are not uniquely defined by filter conditions. That means there can be
rows with different values in the result set.
Missing fields from primary key or secondary keys (list may be
truncated):
&V3&&V4&

System Response

The generated document might contain identical rows.

How to fix this error?

If this behavior is intended, you can ignore this message.
This message might also appear because the underlying query source &V2&
does not describe key fields properly. In this case you should update
that query source if possible.
