Product category could not be identifed uniquely

Hello Everyone,

While trying to enter product category with out using F4 help i am getting error "Product category could not be identified uniquely" BBP_PD273.

As there are two product categories for the same name i.e. one which is created locally (srm) and other which is replicated from ECC(material group).

So how to restrict this error is there any BADI or NOTE please help.

Thanks ,
