Problem with passing itab to program subprogram

[Former Member]

Hi there. I've got a problem with passing itab to subprogram.

DATA: internaltable LIKE dbtable OCCURS 0 .


PERFORM fill_itab USING internaltable .


FORM fill_itab USING itab  LIKE dbtable . 
...  here modify itab ...
ENDFORM.                    " 

I receive an error: In PERFORM "FILL_ITAB", the actual parameter "internaltable" and

formal parameter "itab" are incomapatible.

So ... how should I corretly pass such internaltable itab to the subpprogram?

Greetings. P.

In the FORM statement, you are declaring a one line structure, you need to declare a table here. You could do this in two ways, you can use the USING extension or the TABLES extention.

FORM fill_itab USING itab type table of dbtable. 

ENDFORM.

FORM fill_itab tables itab type dbtable . 

ENDFORM.

 FORM fill_itab USING itab type table of dbtab.  

Returns:

Different number of parameters in FORM and PERFORM (routine:

FILL_ITAB, formal parameters: 3, actual parameters: 1).

 FORM fill_itab tables itab type dbtable .  

Returns:

For typing of TABLES parameters, only table types should be used. -

Hello,

You need first to declare a table type:

TYPES: it_type TYPE TABLE OF dbtable.

FORM fill_itab tables itab TYPE it_type.
 
FORM fill_itab USING itab TYPE it_type.

FORM fill_itab CHANGING itab TYPE it_type.

My apologies. Its a holiday here, so my brain is not up and running yet. Try this.

Create a Table Type using a TYPE statement, and then use this in the FORM statement.

TYPES: ttab TYPE TABLE OF dbtable.

DATA: internaltable LIKE dbtable OCCURS 0 .

PERFORM fill_itab USING internaltable .

FORM fill_itab USING itab TYPE ttab.

ENDFORM.                    "fill_itab
