Error in SPRO

Dear all,

We are trying to create a screen exit for the transactions 'MM41/42/43'. However, when following the below given path in 'spro' we're facing an error "Variant SAP_RETAIL does not exist" (Message 612 (DB)):

spro>Logistics - General> Material Master> Configuring the Material Master> Create Program for Customized Subscreens

Any suggestions as to how to remove this error or create a screen exit in such a case?

Thanks in advance!

Kind Regards,

Devayani
