How to work with deep structure

[Former Member]

Hi !

I wanted to ask how to loop, modify, append tables located in deep structures. Deep structures i mean, structures consist of columns which are tables ( usualy exists in user-exit). Please give examples and reference help to this subject.

Thanks

Hi Moshe,

if you structure looks like :

IS_TOTO

with an internat table TUTU

you could simple do :

loop at IS_TOTO-TUTU.

write : /1 IS_TOTO-TUTU-FIELD1.

endloop.

What is your problem with that ?

Hi

TYPES: T_TYBSEG TYPE STANDARD TABLE OF BSEG.

DATA: BEGIN OF T_DOCUMENTS,

HEADER LIKE BKPF,

ITEMS TYPE T_TYBSEG,

END OF T_DOCUMENTS.

DATA: T_BSEG TYPE T_TYBSEG,

T_BKPF TYPE STANDARD TABLE OF BKPF WITH HEADER LINE.

• Append data:

SELECT * FROM BKPF INTO TABLE T_BKPF WHERE ....

LOOP AT T_BKPF.

MOVE-CORRESPONDING T_BKPF TO T_DOCUMENTS-HEADER.

SELECT * FROM BSEG INTO TABLE T_BSEG where ....

Here it uses the table t_bseg to append the items to T_DCOUMENTS-ITEMS: it's very import to clear this table before appending records.

If you don't clear the internal table you'll append several times the same records.

REFRESH T_DOCUMENTS-ITEMS.

APPEND LINES OF T_BSEG TO T_DOCUMENTS-ITEMS.

APPEND T_DOCUMENTS.

ENDLOOP.

• Read DATA:

LOOP AT T_DOCUMENTS.

LOOP AT T_DOCUMENTS-ITEMS INTO BSEG.

ENDLOOP.

ENDLOOP.

OR

READ TABLE T_DOCUMENTS (WITH KEY ...) (INDEX <INDEX>).

IF SY-SUBRC = 0.

LOOP AT T_DOCUMENTS-ITEMS INTO BSEG.

ENDLOOP.

ENDIF.

Modify

LOOP AT T_DOCUMENTS.

LOOP AT T_DOCUMENTS-ITEMS INTO BSEG.

IF BSEG-GJAHR = '2005'.

BSEG-GJAHR = '2006'.

ENDIF.

...........

MODIFY T_DOCUMETS-ITEMS FROM BSEG.

ENDLOOP.

ENDLOOP.

So if you use this type of structure the table haven't an headerline, so you always use a workarea to read an update the data.

report ztest.

data: begin of itab1 occurs 0,
      uname like sy-uname,
      end of itab1.

data: begin of itab occurs 0,
      matnr like mara-matnr,
      user  like itab1 occurs 0,
      end of itab.
data: wa_user like itab1.
select matnr
       from mara
       up to 10 rows
       into corresponding fields of itab
     .
   endselect.

   loop at itab-user into wa_user.
   wa_user-uname = 'Test'.
   modify itab-user from wa_user index sy-tabix.

   endloop.

thanks
