loop read and modify problem

Former Member — Wed, 15 Nov 2006 07:59:23 GMT

Hellow 1.I wont to doing loop with read and I have a error message the internal table b_itab have no header line I just wont to check if objid in itab = objid in b itab if so modify itab final.

2. do i need to use modify?

TYPES: BEGIN OF 2_itab,

objid TYPE hrobjid,

sobid TYPE sobid,

begda TYPE begdatum,

endda TYPE enddatum,

priox TYPE priox,

sclas TYPE sclas,

myobjid TYPE hrobjid,

END OF 2_itab.

DATA: b_itab TYPE TABLE OF 2_itab,

wa_b_itab LIKE LINE OF b_itab.

LOOP AT itab INTO wa_itab.

READ TABLE b_itab WITH KEY wa_b_itab-myobjid = wa_itab-objid.

IF sy-subrc = 0.

wa_itab_final-objid = wa_itab-objid.

wa_itab_final-firstname = wa_itab-firstname.

wa_itab_final-lastname = wa_itab-lastname.

MODIFY itab_final FROM b_itab .

ENDIF.

ENDLOOP.

Just change the statement a bit

wa_itab1 like line of b_itab.

LOOP AT itab INTO wa_itab.

READ TABLE b_itab into wa_itab1 WITH KEY myobjid = wa_itab-objid.

IF sy-subrc = 0.

wa_itab_final-objid = wa_itab-objid.

wa_itab_final-firstname = wa_itab-firstname.

wa_itab_final-lastname = wa_itab-lastname.

MODIFY itab_final FROM b_itab .

ENDIF.

This should solve your problem

ENDLOOP.

wa_b_itab1 type 2_itab.

LOOP AT itab INTO wa_itab.

READ TABLE b_itab into wa_b_itab1 WITH KEY myobjid = wa_itab-objid.

IF sy-subrc = 0.

wa_itab_final-objid = wa_itab-objid.

wa_itab_final-firstname = wa_itab-firstname.

wa_itab_final-lastname = wa_itab-lastname.

MODIFY itab_final FROM wa_itab_final.

ENDIF.

ENDLOOP.

Change the READ Statement liek above.

Hi,

Check this code....

TYPES: BEGIN OF 2_itab,
objid TYPE hrobjid,
sobid TYPE sobid,
begda TYPE begdatum,
endda TYPE enddatum,
priox TYPE priox,
sclas TYPE sclas,
myobjid TYPE hrobjid,
END OF 2_itab.


DATA: b_itab TYPE TABLE OF 2_itab,
wa_b_itab LIKE LINE OF b_itab.





LOOP AT itab INTO wa_itab.
READ TABLE b_itab WITH KEY myobjid = wa_itab-objid.
IF sy-subrc = 0.
wa_itab_final-objid = wa_itab-objid.
wa_itab_final-firstname = wa_itab-firstname.
wa_itab_final-lastname = wa_itab-lastname.

<b>append wa_itab_final to itab_final.</b>

ENDIF.
ENDLOOP.

Regards

Vijay

Hi,

I have the following suggestions.

1. You are collecting information in the work area WA_ITAB_FINAL and then why u want to modify the table ITAB_FINAL from some other work area? better u replace the modify statement with APPEND WA_ITAB_FINAL into ITAB_FINAL.

2. If you really want to modify then change the statement as follows.

MODIFY itab_final FROM WA_ITAB_FINAL (or some other work area with similar structure. but i dont see any reasons why u should use some other work area). May be u can use the transporting addition.
