logic needed

[Former Member]

I have problem in following logic. S_werks is in selection screen.

read statement is always fails.

for example s_werks = 1201. it_z1ychclientid also have 1201 data

READ TABLE it_z1ychclientid WITH KEY
       werks = s_werks.
IF sy-subrc = 0.
  REPLACE 'PCCCPPPP' WITH it_z1ychclientid-prefix INTO p_pcfile.
  CONDENSE p_pcfile NO-GAPS.
ELSE.
 MESSAGE  text-505  TYPE 'I'.
ENDIF.

write the logic as

READ TABLE it_z1ychclientid WITH KEY

werks = s_werks-low.

IF sy-subrc = 0.

REPLACE 'PCCCPPPP' WITH it_z1ychclientid-prefix INTO p_pcfile.

CONDENSE p_pcfile NO-GAPS.

ELSE.

MESSAGE text-505 TYPE 'I'.

ENDIF.

Use a loop.

loop at it_z1ychclientid where werks in s_werks.

IF sy-subrc = 0.

REPLACE 'PCCCPPPP' WITH it_z1ychclientid-prefix INTO p_pcfile.

CONDENSE p_pcfile NO-GAPS.

ELSE.

MESSAGE text-505 TYPE 'I'.

ENDIF.

endloop.
