Thanks for you answers
I mean someone like this :
TARGET:  TABLE_C
TABLE_A replicat direct to TABLE_C
TABLE_B will replicat only if TABLE_A was replicated and have this values previus add with replicated TABLE_A
how to check if TABLE_A was previously replicated?  is possible on Golden gate ?
create or replace procedure oracle2.lookup_ACCOUNT(acc_code in varchar,acc_cta out number)
as
begin
select count(*) into acc_cta from oracle2.TABLE_B where COLC_1 =acc_code AND COLC_2 =acc_code
end;
REPLICAT rload1
USERID oracle2,PASSWORD extuser2
SOURCEDEFS ./dirdef/defTABLE_A.def <  [TABLE_A + TABLE_B]
DISCARDFILE ./dirrpt/rload1.dsc, PURGE
MAP ORACLE.TABLE_A,TARGET ORACLE2.TABLE_C,&
COLMAP(COLC_1=COLA_1,COLC_2=COLA_2,);
MAP ORACLE.TABLE_B,TARGET ORACLE2.TABLE_C,&
SQLEXEC (ID lookup,SPNAME oracle2.lookup_ACCOUNT , PARAMS (acc_code=TABLEA.COLA_1)),&
FILTER (@GETVAL((lookup.acc_cta) > 0)),&
COLMAP(COLC_3=COLB_1,COLC_4=COLB_2,);
Thanks
