READ_KNA1

[Former Member]

Hello Friends.

I am trying to use READ_KNA1 function module in a program to get some detials fom KNA1 table. However the following code does not give any results, just giving a blank screen.

I do not understand what am I doing wrong?

Can any one help me.

Regards,

Murali.

DATA: YKNA1 LIKE KNA1 OCCURS 0 WITH HEADER LINE,

XKUNNR LIKE KNA1-KUNNR.

XKUNNR = PKUNNR.

CALL FUNCTION 'READ_KNA1'

EXPORTING

XKUNNR = XKUNNR

IMPORTING

XKNA1 = YKNA1

EXCEPTIONS

KEY_INCOMPLETE = 1

NOT_AUTHORIZED = 2

NOT_FOUND = 3

OTHERS = 4.

IF SY-SUBRC <> 0.

ENDIF.

You have to left pad PKUNNR with zeroes.

This sort of question has been asked and answered many times before - please search before posting.

Hello Murali

Your negative result is the consequence of poor programming.

A simple change in your program would have solved this (answer of Rob):

...
" PARAMETERS: PKUNNR(10).
PARAMETERS:  p_kunnr    TYPE kunnr.
...

Using the correct type for your PARAMETER the system would "know" that is has to use the conversion-exit assigned to the domain of data element kunnr.

My question was very basic, as I am beginner in ABAP programming.

Thanks Rob and Uwe.

Problem solved.
