How To Fix CNV_PE_GEN097 - Extension content potentially unneeded, but storage active for area &2

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_PE_GEN - Messages for object generation

• Message number: 097

• Message text: Extension content potentially unneeded, but storage active for area &2

What causes this issue?

In the transformation rules called within this transfer method &V1&, no
extension parameter of type table is present as input parameter in the
signature.
In the knowledgebase for transfer method &V1&, no extension parameter is
defined as sender parameter.
As both aspects are valid, then for this transfer method - during the
build up of the transfer list - it is not required to import the
extension content of each worklist item from the respective DB table.
To make the extension content available at all for import it must be
stored in a respective database table during the creation of the
worklist. This is indicated by the <ZK>Store Extension</> indicator on
area level. This storage is not required for this transfer method as
potentially stored data is not imported anyway into any transformation
rule of the transfer method.
Nevertheless it is possible that further transfer methods are existing
in area &V2&. (Transfer method &V1& belongs to area &V2&). These further
transfer methods may in fact need an import of the extension content
during the build up of the transfer list.

System Response

It is possible that the respective extension table is directly accessed
within the source code of a transformation rule or in any customer
programs. This cannot be checked automatically. Therefore the storage of
extension content is not deactivated, if it has ever been activated
before.
Deactivating the storage of the extension content (on area level) and
importing the extension content will however decrease the processing
time.
The program found that the storage of extension content is active in
area &V2&, despite of the fact that the extension content might not
needed.

How to fix this error?

If you are unsatisfied with the performance of <ZK>build up of worklist
</>and <ZK>build up of the transfer list</>, then check whether
deactivating the <ZK>Store Extension</> indicator in area &V2& is
possible.

Procedure for System Administrators
