For material, there is a fileds product hierarcy (MARA-PRDHA) on Basic view, but we also append the same field in materail sales view (MVKE-PRDHA) and put on the screen of sales view, so the user want the PRDHA on sales view could be updated automatically when it has been changed on Basic view. On the screen of basic view, the field MARA-PRDHA is set as parameter ID 'VPR', the sales views are updated in function module MVKE_SET_DATA, so how can I get the value of parameter ID 'VPR' in MVKE_SET_DATA to populate the value in Sales View?!
Does parameter IDs and their values locate in global memory?!
if yes, why i can't get it with: GET PARAMETER ID "VPR' <f>?
