I have implemenated BADI ME_PROCESS_PO_CUST to process a particular field in a PO during creation in ME21N or ME59N, it is all working fine. However, I also want to change the field properties using this BADI, I hope someone can give some advice.
Essentially, when field EKPO-BEDNR is populated by the BADI using PROCESS_ITEM, I want the field to change to display only. I a assuming method IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM can be used for this, but I cannot find any documentation on it.
Any advice on how to change the field properties is greatly appreciated.
Note: I have tried to use SAP standard field selection in customizing but this is not possible to achieve what is required, the only route is through the BADI.
