Copy and Modify from one internal table to another.Please help.

Question

Hi,
I have an internal table having a structure like below.
Account Entity Category period1value pd2value
10 A C 100 200.
where account corresponds to 10
entity A
category C
period1 value = 100
period2 value = 200.
Now I need to populate it into another table having structure like
Account Entity Category period Value
10 A C 1 100
10 A C 2 200.
If u see this carefully a new column, period is added in the database table and thus for each row there will be only 1value.
Instead of period1 value and period2 value being in the same row they will come in different rows.One row will be like the value for period1 and next for value like period2.

Hi,
u can do as follows,
LOOP AT itab1 into wa_itab1.
wa_itab2-account = wa_itab1-account.
wa_itab2-entity = wa_itab1-entity.
wa_itab2-category = wa_itab1-category.
if not wa_itab1-period1 is initial.
wa_itab2-period = wa_itab1-period1.
endif.
if not wa_itab1-period2 is intial.
wa_itab2-period = wa_itab1-period2.
endif.
wa_itab2-value = wa_itab1-value.
append wa_tab2 to itab2.
clear:wa_itab1-period1 ,
       wa_itab2-period .
endloop.
