How to Generate Serial Number during the Return To Vendor Transaction for non Serialised Item

Hi All;

I want  to use the 12.2.3 new functionality of Serial Tagged during Return to Vendor process

I have tagged my Item (with serial Generation is 'No Control') in other to generate serial number during Return to vendor transaction

this setup was made at Mater and propagate to child organisation

when I perform the Return to vendor transaction against a received PO,

the field LOT/SERIAL is greyed and I'm able to save the return transaction without any lot serial information

.

Do I missing some setup?

thanks for any reply
