I am currenly using S/4Hana 1809 on premise.
I have a very simple requirement to add some cusom fields in BP at the general data level (BUT000) and also display the same in a new Custom Tab in BP Transaction Code.
I am able to add the Z fields at table level using the include CI_EEW_BUT000, but not able to add them in screen in Txn BP.
I tried to search the SAP blogs, but could not find enough adequate information.
If you have got the answer, please share with me.
