INTERNAL TABLE

Former Member — Thu, 23 Feb 2006 15:56:02 GMT

Hi All,

I have seen in a program the internal table like this:

data: begin of i_table,

record(2) type c,

matnr like mara-matnr,

smatn like knodd-smatn,

laeda like mara-laeda,

......................

end of i_table.

and he's using that internal table later on in the program.

but when i tried to add some more fields to that internal table and use, it's giving syntax error saying that "OCCURS n" specification is missing.

How come he could used that internal table without "Occus n" specificaiton, and why it is giving error for me now.

plz clarify.

thnx a lot.

he might have used it as TYPES, is the code posted by u the same as written by him

data: begin of i_table occurs 5,

record(2) type c,

matnr like mara-matnr,

smatn like knodd-smatn,

laeda like mara-laeda,

data: begin of i_table occurs 0,

record(2) type c,

matnr like mara-matnr,

smatn like knodd-smatn,

laeda like mara-laeda,

......................

end of i_table.

occurs 0 is missing..

Hi Venugopal,

Check in the same program,he must have defined some other internal table & used this structure.

like..

DATA: I_TABLE1 LIKE I_TABLE OCCURS 0 WITH HEADER LINE.

Hi,

without the OCCURS you have define a structure not a table. So you can't append anything.

Maybe you will have later a command like :

data : it_table like table of i_table with header-line.

no, u got me wrong.

that program was working fine without "occurs n" specification earlier.

but when i tried to add some more fields to that, it is giving errors?

my question is: how come that program worked fine earlier without that "occurs n" specification?

hope it is clear now.

there is not such "TYPES" mentioning and no "WITH HEADER LINE" mentioning.

Hi Venu

if you are trying to populate the internal table with the rows then you should specify the occurs n statement so that the system allocates the necessary memory for the internal table.

Hi Venu gopal,

According to the definition,it is a structure.He must have defined a internal table with that structure.

But when you define a tbale without occurs n,it is a structure.

Hi Venu,

then they might have declared it some where like this

data: itab like i_table occurs 0 with header line.

so the error is coming because you might have used some where you are doing one of these..'

loop at i_table. or read table i_table or select into i_table

See where that strcuture is used and give us the code

If we use DATA without occurs it acts as a structure

u might have tried to Loop at that internal table , so it gave u the error

Re: INTERNAL TABLE

Former Member — Thu, 23 Feb 2006 16:10:01 GMT

The program may be earlier populating only Header and not the Body. Just check whether earlier append statement was there before your more fields addition? If this was there earlier too then you would have encountered the same problem earlier too.

Re: INTERNAL TABLE

Former Member — Thu, 23 Feb 2006 16:29:10 GMT

When you added the extra fields, did you also add some coding like: append i_table or loop at i_table? That would explain why it worked before but not after your changes.

Re: INTERNAL TABLE

Former Member — Thu, 23 Feb 2006 16:47:30 GMT

yes. you all r correct.

it was just a structure earlier.

now after adding the fileds, i'm trying to do the "append itab" and "loop at itab".

tht's why it is giving the error.

tht's cleared now.

could you please tell me how to overcome this?

now that i'm trying to add some more fields to that stucture and trying to do the "append" and loop at itab", how should i proceed for that changes to be done?

thnx a lot.

Hi Venu gopal,

Declare another internal with this structure.Or just add OCCURS 0 to the existing definition of the internal table.

Also you can add your additional fields to this internal table definition.

declare like this

add the fields u want to the structure and declare like this

data:it_table like i_table occurs 0 with header line.

Just look for the

decalration of

data: itab like i_table occurs 0 with header line.

do operation on the table itab.

what ever you want to do , loop or what ever..

You're really changing the logic of the program. Without knowing the new requirements, it's hard to tell you how to proceed.

In particular, the old logic may not work if you simply change the structure to an internal table.

Re: INTERNAL TABLE

Former Member — Thu, 23 Feb 2006 17:47:55 GMT

the existing structure is like this, right.

data: begin of i_table,

record(2) type c,

matnr like mara-matnr,

smatn like knodd-smatn,

laeda like mara-laeda,

......................

end of i_table.

now i want to populate this stucture as an internal table , with adding my 3 more fields.

the extra 3 fields i should add are:

ex_f1 type c,

ex_f2 type c,

ex_f3 type c,

how can i do that?

thnx

Hi,

what do you mean by this...

data: itab like i_table occurs 0 with header line.
extrafiled1 type c,
extrafield2 type c,
extrafield3 type c.

and add those fields to the structure, since it is a structure , you/some one might have delcared internal table based on it, and populate the fields to that itab,

...
