Blocking PO creation for Materials

Hi !

The procurement block on the material master can be applied on the Purchasing view using the 'Plant Specific Material Status'. I was wondering if this can be made document type specific as well.

We have document NB for regular POs, and ZRT for return-to-vendor POs. We would like to prevent the creation of NB POs via a error message, but allow creation of ZRT POs, for specific materials.

This would be necessary, for example, when a product is under recall.

Please let me know if there is a way to accomplish this.

Thanks!

Anisha.
