How To Fix NRSCNV142 - Temporary DSO &1 already exists (delete)

NRSCNV142 - Overview

• Message type: E = Error

• Message class: NRSCNV - Message class

• Message number: 142

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

What causes this issue?

The check on DataStore object &V2& returned an error because an
DataStore object called &V1& already exists. Since the remodeling
framework will create a temporary DataStore object called &V1&, it must
be ensured that this DataStore Object does not exist before running the
remodeling rule. The reason for DataStore object &V1& existing could be
as follows:
DataStore object &V2& has already been remodeled before, but the
remodeling run did not finish successfully. The temporary DataStore
Object created during this previous run therefore was not removed
DataStore object &V1& is a real DataStore Object and was not created as
a temporary DataStore object 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
temporary DataStore object &V1& in transaction RSDODS. If the second
case applies, change the prefix character used to create a temporary
DataStore Object. 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 DataStore object created by the remodeling framework can
also be identified by its description, which should look something like
this: <ZK>TEMPORARY CUBE FOR REMODELING OF CUBE <(><<)></> DataStore
Object<ZK> name></>.

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