I have a z table in data dictionary with fields f1 f2 and f3. f1 and f2 form the primary key,
Now i have an itab with fields f2 and f3. I want to update the table ztable from the itab for a key f1(which i already have ).
I have tried modify ztable from itab where f1 = f1. but it doesnt like it.
Can you please advise what will be the best way
