Hi Dinesh,

Please check the below code to validate:

IF NOT S_BUKRS is initial.

select bukrs into t001-bukrs upto 1 rows from t001

where bukrs in s_bukrs.

end select.

if sy-subrc ne 0.

message e594.

endif.

clear: t001.

Sales distribution channels for a particular sales organisation

TVKO -->sales organizations

check the table

TVKOV for distribution channels . " validations

all this are related to sales area .

so in the at selection screen events use the check tables for validations.

hi,

since your requirement is to get all distribution channels for a given sales organisation you need to perform validation for the sales organisation you enter. So, you would probably get the input for sales organisation, for this perform validation at selction screen. And then you could select the distribution channels for the same.

For validating a selection screen field, u should consider the header table that is a must.

Eg: My selection screen field is marc-matnr.

<b>U have to see whether the matnr in marc is having any check table if so u have to refer the check table not marc.</b>

So to validate this fiedl.

SELECT-OPTIONS: s_matnr LIEK mara-matnr.

AT SELECTION SCREEN ON s_matnr.
 IF NOT s_matnr[] IS INITIAL.
  select matnr from mara
                     into mara-matnr
                     where matnr = s_matnr.
  IF sy-subrc NE 0.
    MESSAGE i128.
    LEAVE LIST-PROCESSING.
  ENDIF.
 ENDIF.

Hope this solves ur query.
