Selection Screen Data Validation

[Former Member]

Hi All.

I have made a program with vendor and purchase order inputs. If I give the correct vendor and PO it works fine. I want to implement validation. For that I have an internal table with vendor and all the PO's raised on him. Now I have to validate 1. vendor, 2. PO and 3. if a PO not of that vendor is entered then to display a message. I tried some option but the error message comparing the vendor and PO doesn't work. Can anyone give an idea please. Tks & Best Regards.

Hi,

Validate Vendor in LFA1-LIFNR , PO in EKKO-EBELN

and combination as :

select EBELN LIFNR

from EKKO

into table itab

where EBELN = p_ebeln

and LIFNR = p_lifnr.

if sy-subrc ne 0.

Message 'error message'.

endif.
