Check budget for GI posting

Dear all gurus,

I have no idea to set "derivation rule" for this case then please help me to find the solution.

I have set derivation rule for not checking budget for all inventory movement type as the budget was already checked in the step PR/PO and will update the budget again on IR. Now there's a new process of clients as "vendor consignment" (vendor lends goods and the customer will pay when using it). The step of this process is creating PR/PO with item catagories "K" then no fund check. Fund will be checked in step GI but in this case is GI to PM order then no any fund center to check budget. In this case, budget should be checked for fund center of equipment's owner that specify in PM order.

Anyone has idea to share with me? Now i add the condition of checking GI to check "special stock <> K" already but don't know how to get fund center from this screen.

Thank you
