Validation using chain ... endchain

Former Member — Thu, 24 Jul 2008 22:28:08 GMT

Hi,

I am using chain...endchain for 8 fields to validate duplicate entries.

It is giving an error message when there is a duplicate entry and allows me to delete the entry, but the error message still appears as the value still remains in the internal table that i use for validation.

The message continues to appear until i delete enties in all the 8 fields, and i am not able to enter the value which has been once used and deleted.

here is the example code that i used to validate:

IF it_parvw IS NOT INITIAL.

CLEAR: lv_count1.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw1.

lv_count1 = lv_count1 + 1.

IF lv_count1 GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count2.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw2.

lv_count2 = lv_count2 + 1.

IF lv_count2 GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count3.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw3.

lv_count3 = lv_count3 + 1.

IF lv_count3 GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count4.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw4.

lv_count4 = lv_count4 + 1.

IF lv_count4 GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw5.

lv_count = lv_count + 1.

IF lv_count GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw6.

lv_count = lv_count + 1.

IF lv_count GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw7.

lv_count = lv_count + 1.

IF lv_count GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

CLEAR: lv_count.

LOOP AT it_parvw INTO wa_parvw WHERE parvw EQ vbak-zzparvw8.

lv_count = lv_count + 1.

IF lv_count GT 2.

MESSAGE 'Duplicate Partner Types entered' TYPE 'E'.

ENDIF.

ENDLOOP.

ENDIF.

Please let me know how to solve this problem.

Thanks.

Loop at itab.

chain f1

f2 .....f8

module check_dupliacates.

endchain.

endloop.

I believe as soon as you enter some data in any of these fields of internal table and hit enter you have to validate for duplicacy.

module check_dupliactes.

temp[] = itab[].

Delete the current line from the temporary table

delete temp index sy-stepl.

Read the temporary table for matching partner type. If

*an entry is found in internal table then it's a duplicate *otherwise proceed with it

read table itemp withkey ...

end module.

reward if useful.

Hi,

Thanks for the idea.

I tried it but it is giving a dump in runtime at the delete temp statement as sy-stepl is always showing 0.

Could you pls help me?
