Passing Tables dynamically to Form

[Former Member]

Hi,

I have a small peculiar requirement, I have to pass an Internal table dynamically to

a form. Actually, this form should work for four different internal table of different types. But, the logic is same for these four tables. Depending on some condition, I

will pass different internal table to that form.

for example, I have written the code like this:

if cond1..

perform form_name using it_table1.

elseif cond2.

perform form_name using it_table2.

elseif cond3.

perform form_name using it_table3.

elseif cond4.

perform form_name using it_table4.

endif.

form form_name using it_table type any.

loop at it_table.

-

---

-

---

endloop.

endform.

This code is giving the error "it_table is not declared as table or Generic type'.

How to handle this scenario?

Could you please anybody help on this...

Thanks,

Change this :

form form_name using it_table type any <b>TABLE</b>.

loop at it_table.

-

---

-

---

endloop.

endform.

This should do.

Hi Srihari,

Agaun it is giving error like ' formal parameters and actual parameters are incompatable'

Have you defined a header line for your internal table ??

If yes, try to avoid it.

If you cant :

Call the perform like this

perform <form_name> using it_table[].

Can you please post a part of your code:

1) Your data declarations

2) Perform call

3) Form routine

Hi,

may be this way.

define form_name.
loop at &1.
----
----
endloop.


endefinition.

if condition eq 'XXXXXXXX'
form_name it_table1.
form_name it_table2.
form_name it_table3.
elseif cond4.
form_name it_table4.
endif.

Only disadvantage by using macro. within the loop you could not debug

Hi,

Please try this.

If <cond1>.
  perform form_name tables it_table1.
elseif <cond2>.
  perform form_name tables it_table2.
elseif <cond3>.
  perform form_name tables it_table3.
elseif <cond4>.
  perform form_name tables it_table4.
endif.


form form_name tables p_table.

  loop at p_table.
    ...
  endloop.

endform.

Hi,

This is one of the way. It uses field symbols.

For Eg:

PERFORM appl_upload USING gv_header 'gt_header[]'.

PERFORM appl_upload USING gv_header1 'gt_header1[]'.

PERFORM appl_upload USING gv_header2 'gt_header1[]'.

Here gt_header, gt_header1 and gt_header2 can have different structures. As you can see you are just passing the name of the table as a constant.

FORM appln_upload USING gv_header type ...

tabname type string.

FIELD SYMBOL: <tab> type any.

ASSIGN (tabname) to <tab>.

LOOP AT <tab>..."can do u r processing.....

ENDFORM.

So in the form as u can see, u pass the tabname to the fieldsymbol.

In this way you can use the same perform though the structurs used in it are different.
