How to display in FB01 the field LOKKT - Alternative reconciliation account

Hello,

I'd like to understand how to display in FB01 transaction the field LOKKT.

I activated the customizing of the alternative reconciliation account. I added a reconciliation account linked to many reconciliation account. I need to understand if during the posting of a vendor invoice is possible change the reconciliation account.

I changed the account from FS00 with the flag to allow alternative reconciliation account.

Also I checked the field status group of the account and the posting key.

Thanks a lot in advance

Kind regards.
