simple logic from below internal tables

Hi,

I have one i.table ITAB.

entries as:

Year Month value

2008 12 0.00

I have another i.table ITAB1

entries as:

Year Month value

2008 1 12.00

2008 2 15.00

2008 3 10.00

2008 4 11.00

2008 11 0.00

2008 12 0.00

Both these i.tables are retrieved from same table.

Now i required logic such that i should be able check each month 12-1, 11-1 etc.. till the month have some value other than 0.00.

Note: i should not use

Loop at ITAB.

If itab-value eq 0.

• logic should pick up value from previous available month which have value from ITAB1

endif.

endloop.

can anybody provide simple logic for this!

Thanks,

Deep.
