Help reqd - Data declaration

Former Member — Thu, 27 Mar 2008 17:31:02 GMT

Hi,

I have a problem here. I am analyzing an existing program. This is an active prg in Production.

In that I see usage of an internal table called 'itab1'. On double clicking on it (to find it's data declaration) it takes no-where. It asks if I would like to create it.

In an include program (which in embedded in this main program), I find some declaration as follows:

data: itab&1 like &2 occurs 0 with header line.

Can you help me understand this? I need to change the data declaration for this 'itab1' for an upgrade.

Regards,

Sanju.

Sanju,

Welcome to SDN

Is that statement is commented? if it is commented i think it will not takes no where.

Uncomment it once, double click on it and see.......

You can change the data declaration and it should not give you any problems.

In stead of declaring the data in the report itself, an include is used to do (all) data declaration. The fact that you don't jump to the data declaration upon double clicking can be caused by the fact that the navigation index is not up to date.

You can do this in the menu (utilities I believe) and choose 'update navigation index'. Try this and then again try to double click on itab1. Check if it works now.

No Naveen.. It's very much uncommented and in use.

hi ,

if u double clicking the itab it is not taking any more means it is not used or it is called dynamically...

data: itab&1 like &2 occurs 0 with header line.

i think this is done in the oops abap ....

I dont think that its a commented statement.

May be Internal table is declared at runtime.

so, put a break point and execute the program and see what happens...

cheers!!!

Not sure, but this can be a dinamic declaration for this internal table's name using two macro parameters.

This probably is part of a macro which has the parameters &1 and &2.

Yes Rodrigo.. You are correct.. the 'itab&1' is inside a macro.

So, what's the connection between 'itab1' and 'itab&1'? All I need to do is change the declaration of 'itab1'..

Please help.

I can try executing this program but it needs an input file which I dont have a this moment..

I believe the definition is made by a macro, something like this:

DEFINE INT_TABLE.
  DATA: ITAB&1 LIKE &2 OCCURS 0 WITH HEADER LINE.
END-OF-DEFINITION.

INT_TABLE 1 BKPF.
INT_TABLE 2 BSEG.


START-OF-SELECTION.

  LOOP AT ITAB1.
    LOOP AT ITAB2 WHERE BUKRS = ITAB1-BUKRS
                    AND BELNR = ITAB1-BELNR
                    AND GJAHR = ITAB1-GJAHR.
    ENDLOOP.
  ENDLOOP.

In this way I define 2 internal table ITAB1 like BKPF and ITAB2 like BSEG.

So u need to find out when that macro is called in order to define ITAB1.

Macros are defined using the following statement:


DEFINE conversion.

  if &1 is not initial.
    &2 = c_X.
  else.
    &2 = space.
  endif.
 

END-OF-DEFINITION.

You apply it like described bellow:


  conversion var_1 var_return.

My guess is that this internal table is being declared using the macro parameter. so, if &1 is valued with "10", that internal table will be named itab10.

Not quite sure about that, but maybe that's what is happening. Try to find the place where the macro is being called and see if &1 value is '1'.

Yes Max.. Inside the macro I see this kind of thing

DEFINE INT_TABLE.

DATA: ITAB&1 LIKE &2 OCCURS 0 WITH HEADER LINE.

END-OF-DEFINITION.

But I don't see anything as below in the include program that has the macro definition.

INT_TABLE 1 BKPF.

INT_TABLE 2 BSEG.

Perhaps it's passing any variable instead of 1...

Yes I know, your macro should have a different name: in my sample I call the macro INT_TABLE, but I suppose it'll be different in your code.

So go to the macro defination:

DEFINE <MACRO NAME>.

DATA: ITAB&1 LIKE &2 OCCURS 0 WITH HEADER LINE.

END-OF-DEFINITION.

Find out the name of the macro and check where it's used.

If you have a table ITAB1 you should find a line similar to this:

hi use this ...

data: test LIKE CAWN-ATWRT value '20080327',

out like CAWN-ATFLV .

CALL FUNCTION 'CTCV_CONVERT_DATE_TO_FLOAT'

EXPORTING

DATE = test

IMPORTING

FLOAT = out.

write:/ out.

Yes Max.. I understood your point before itself.. My macro is called 'file_select'

DEFINE file_select.

*--- Internal table for file contents

data: itab&1 like &2 occurs 0 with header line.

more data declarations

selection screen definition

END-OF-DEFINITION.

Then I do CNTL F for 'file_select' and don't see in anywhere in that include. Thus I am not able to see what &2 or &1 means.

Sorry Venkat that wouldn't help.. Later on internal table itab1 aquires value from itab2

itab1[] = itab2[]. So, I need to change the type of itab1 to suit to that of itab2.

You searched only in the include or also in the main program?

Re: Help reqd - Data declaration

Former Member — Thu, 27 Mar 2008 18:15:40 GMT

Both..

Re: Help reqd - Data declaration

Former Member — Thu, 27 Mar 2008 18:17:25 GMT

Is the code too long?

Could you post it?

Re: Help reqd - Data declaration

Former Member — Thu, 27 Mar 2008 18:19:57 GMT

Sorry

Can u post all codes in your macro definition
