Missing field in Field Catalog

[ole_geismar2]

I need to define a new condition table for Invoice Output Determination based on Payment Term (VBRK-ZTERM).

ZTERM was not present in the Field Catalog for Invoice Message; V_T681F; Usage "B", Application "V3" and Field Group "001", so I added it here, using transaction SM30.

ZTERM is present in both VBRK and KOMKBV3, so there should be no need for filling it in RVCOMFZ1 form USEREXIT_KOMPBV3_FILL, or RVCOMFZZ form USEREXIT_KOMKBV3_FILL.

Now, using transaction V/62, I try to make a new condition table based on ZTERM, but ZTERM is not available to choose in the rightmost column, where all the other fields from the (B,V3,001) field catalog are found..

I must be missing something... But what is it?

The problem is that ZTERM is not among the standard available fields, so the only solution is to make it available, creating a ZZcomponent as described in https://blogs.sap.com/2013/01/23/enhancing-the-condition-table-field-catalog-for-output-billing/.

So, an extra line in RVCOMFZZ form USEREXIT_KOMKBV3_FILL is required.
