How To Fix NRSCNV306 - Temporary InfoObject &1 already exists (delete)

SAP Error Message - Details

• Message type: E = Error

• Message class: NRSCNV - Message class

• Message number: 306

• Message text: Temporary InfoObject &1 already exists (delete)

What causes this issue?

The check on InfoObject &V2& returned an error because an InfoObject
called &V1& already exists. Since the remodeling framework will create a
temporary InfoObject called &V1&, it must be ensured that this
InfoObject does not exist before running the remodeling rule. The reason
for InfoObject &V1& existing could be as follows:
InfoObject &V2& has already been remodeled before, but the remodeling
run did not finish successfully. The temporary InfoObject created during
this previous run therefore was not removed
InfoObject &V1& is a real InfoObject and was not created as a temporary
InfoObject during a previous remodeling run

System Response

Activating, scheduling or running the remodeling rule is not possible.

How to fix this error?

If the first of the two cases described above applies, simply delete the
temporary InfoObject &V1& in transaction RSD1. If the second case
applies, change the prefix character used to create a temporary
InfoObject. In the default setting, the prefix character is <ZK>Z</>.
You can change this by opening the configuration screen by pressing
<ZK>Configure</> or choosing <ZK>Remodeling Rule -> Configure</>.

Procedure for System Administrators

A temporary InfoObject created by the Remodeling framework can also be
identified by its description, which should look something like this:
<ZK>TEMPORARY IOBJ FOR REMODELING OF IOBJ <InfoObject name></>.
