I need to know how to change the value of an item in the line of internal requisition?

We're creating an Internal Requisition and have Implemented the Custom Price Hook code (that is to say, I have customized file POXPXPRB.pls, PO_CUSTOM_PRICE_PUB.GET_CUST_INTERNAL_REQ_PRICE function as per the documentation).

Our change is to change the value of the unit price of the request line When the item is the value is null or zero.

When you generate the request by IPROC the value of the line item remains zero.

Even after the approval of the Request the zero value remains.

When you generate the request by IPROC the value of the line item remains zero.
