Link Production Order to Sales Order

Hi,

Have some questions on the “LINK PROD ORDER” button on the sales order, or the “LINK SALES ORDER” button on the production order.

1. Is it possible to fill out a resulting pop up like this via the API?

2. If not, how can I fill out the fields under “REFERENCES>SO REFERENCES” (SO Order Type, So Order Nbr, SO Line Nbr) on the Production Order when they are greyed out? Is there a way to un-grey these?

3. If not, how can i fill out the fields under the line item on the Sales Order (Prod. Order Type and Production Nbr) when they are greyed out?

Any help is much appreciated!!!
