Hi experts,

What is the meaning/use of this code?

DATA BEGIN OF MY_TEXT OCCURS 1.

INCLUDE STRUCTURE BAPITGB.

DATA END OF MY_TEXT.

This creates an internal table with name MY_TEXT and this internal table has the structure of BAPITGB.

The idea behind this is to reuse the structure created the dictionary while creating the internal table.

This could be as simple as

DATA : MY_TEXT TYPE TABLE OF BAPITGB.

The code craetes an internal table with one component named LINE. The component LINE is character type with length 255. This internal table can be used is a program to carry a text in 255 character format.

The syntax 'include structure' creates components in internal table. In this case the structure BAPITGB has only one componet called LINE.

Hi experts,

What is the meaning of the occurs 1 in the code?

Hi Marc,

The main purpose of this is you can add more fields in addtion to included structure to your internal table.For example.

For your internal table "itab" you want to add all fields structure "A" & some of the fields from Structure B.

Suppose if structure A is having 100 fields and from B you are adding 3 fields.

In practical you can not declare all 100 fields from A and 3 fields form B in your internal table.

For that reason Include structure is useful.See the below code.

DATA BEGIN OF MY_TEXT OCCURS 1.

INCLUDE STRUCTURE BAPITGB.

XYZ like mara-matnr,

klm like viqmma-qmnum,

ghi like kna1-kunnr,

DATA END OF MY_TEXT.

Pls. reward points if it is helpful......

OCCURS clause is telling the system the expected number of rows in the internal table.

however, with the latest versions this syntax is not necessary any more and will become obsolete eventually.

Hi experts,

I can't seem to know what's wrong with the code

Syntax error:

"MY_RETURN" cannot be converted to a character-type field

Here is the code:

REPORT z_test_nmc5.

my_message_v1 LIKE bapiret2-message_v1, " Message Variables

my_message LIKE bapiret2-message, " Message Text

my_return TYPE bapiret2. " Return Parameter

DATA BEGIN OF my_text OCCURS 1.

INCLUDE STRUCTURE bapitgb.

DATA END OF my_text.

hi,

Hullo,

I'm guessing you're using a UNICODE version of SAP (4.7 or higher)..

Your problem is that you're getting a syntax errror when trying to write my_return.

your problem is that my_return is not a single variable but a structured variable (or workarea). IIRC as soon as there are non-c type fields in a structure you can't write the whole structure as one big variable (hence the error: "cannot be converted to a character-type field").

the following code:

data: ...
      ...
      my_return TYPE bapiret2. " Return Parameter

is your problem.

You should declare the my_return vatiable according to the field of bapiret2 you want to use instead of the whole structure. Just like you have done with all the other 'my_...' variables.

Or, if you meant to use the whole structure, you'll have to write each field separately, insted of the whole structure in one go.

Hope this helps.
