In our CV we use complex logic:

var_eban = CE_COLUMN_TABLE("ECC"."EBAN");

var_mseg=...

var_out=....

If I understand correctly when we use filter in BOBJ(which generate SQL: select "BANFN","MENGE" from "SYS_BIC/CV1" when "BANFN"=input from user) CV read all information from all BANFN .And only after this system run our filter on one banfn. It's too long.

Any chance to transfer information from BOBJ 4 selection screen to CV logic, for examle to var_eban. I want to run CV only on one banfn but not on all.
