PM/MM User exit COZF0001 to change created (in IW31) PR fields in ME52N
An PR has been created automatically when user create Work Order via tcode IW31.
This auto generated PR have requirement from user to be manually changed via tcode ME52N.
Currently, the auto generated PR (from tcode IW31) will not allow user to change in ME52N as all fields are in grey off (non-editable mode).
I have activated an user exit called COZF0001 via CMOD, but only a few fields turns to grey out (editable fields) like Purchasing Group, Requisitioner, Tracking Number, Fixed Vendor, Purchasing Org.
While others like Delivery Date, Material Group, Storage Location still in grey off (non-editable mode).
I have checked EBAN_ORD_CUST and found that Delivery Date, Storage Location already inside the structure, but the fields in ME52N still not turn to grey out.
Really appreciate if anyone could share his/her expert advice, thank you in advance.
