Classic PO with catalog item

Hi

We are on SAP SRM 7.13 SP01 with ECC 6.07, Classic scenario, integrated via PI.

We are using SRM-MDM Catalog and creating POs in backend successfully (free text item, no integration from contract, no purchase info recrods, nor material master).

When we create a PO with a catalog item, we have no indicator/flag in ECC that this position comes from the MDM catalog.

Is there any standard way to acknowledge this in ECC? Any report?

Thank you
