Hi,
Assuming that all the internal tables would be the same type:
within the perform it would not be necessary to know exactly which table name is being used. Instead, internal tables will be passed to the form and will be handled as "formal" parameters inside this form. Then, when returning to the main program, you will be able to distinguish which internal table has been passed to the form.
An example would be:
report ....
data: begin of itab1 occurs 0
f1 type n,
f2 type n
f3 type n,
end of itab1.
data: begin of itab2 occurs 0,
f1 type n,
f2 type n
f3 type n,
end of itab2.
...
as you can see, itab1 and itab2 have really the same structure, so you can also declare them in the following way:
data: begin of wa_itab,
f1 type n,
f2 type n,
f3 type n,
end of wa_itab.
data: itab1 like wa_itab occurs 0 with header line,
itab2 like wa_itab occurs 0 with header line.
......
Then, you could create a form routine in your report similar as:
form fill_tables tables aux_itab structure wa_itab. --> (wa_itab was declared at the beggining of your report)
select * from xxxx into corresponding fields of table aux_itab. (here, aux_itab is the "alias" for the internal table which has been passed to the form)
...
(like this you could fill your internal table as needed),
endform.
....
Then, in your main program you would call the form like this:
perform fill_tables tables itab1.
perform fill_tables tables itab2.
or, you can also call the form like this:
perform fill_tables tables: itab1, itab2. (this means that you will call the form twice)
You can also find more help by pressing 'F1' on the statement "perform" in your ABAP editor. This will show a lot of suggestions about syntax for statement perform/form.
I hope this is useful for you.
kind regards,
