Acceptance Required Defaulting Rule in Purchase Document

Dear Expert,

As per reference in Online User Manual, Acceptance required in Blanket release if controlled in Agreement (Blanket Purchase Agreement)

if Blanket release from BPA which is Acceptance required then, it Is required acceptance.

We have issue that, acceptance required flag is always defaulted from Purchasing Option.

If set purchasing option document or shipment, then in BPA is blank, when doing release

it always defaulted to purchasing options value.

Anybody can advise, any patch or solution for this?

Thanks
