Adding new record to ZTABLE from 2 ITAB

hi everyone,

I have requirement, where i have to add new records into ztable based on 2 condition.

for the 1st condition i am using itab1  and getting value into it.

for the 2nd condition i am using itab2 and getting value into it.

My wa1 and wa2 contains same fields.

But the values in ITAB1 will be different from ITAB2.

Currently i am inserting ztable seperately each time for this ITAB1 and ITAB2.

Now i wanted to know whether it's possible to combine this itab1 and itab2 into a final itab (ITAB_FINAL), If so explain me, With Ex.

With Regards,
