GRPO DueDate Should Come as per Payment terms.

Hello Experts,

I have stuck up at one point,

I want to setup DueDate in GRPO & Delivery Date in Purchase Order as per Payment terms set in BP Master Data.

For Due Date in AP Invoice,Payment Terms are giving correct Date but in GRPO & PO it not giving any change menace

in PO & GRPO Due Date is same as Posting Date.

I am using SAP B1 8.80 SP 00 PL 10

How Can i do this??
