How to Desable (Non Editable, Grayed out) NETPR field on PO line item
I have a requirement where in PO I need to make NETPR (Net Price) non editable based on GR status.
For this BAdI 'me_process_po_cust' has to be used and method 'fieldselection_item'.
In this method we have got an internal table 'ch_fieldselection' that actually allows to change the field properties.
The issue is I am not getting NETPR value in it in anyform (MMMFD code is used inside it).
Can anyone please help me in how to get NETPR field value in ch_fieldselection table? or is there any other way i can achive this functionality of desabling NETPR field on line item of PO.
