Hi Murli,

The select-option is stores the data as an internal table and strctly validation to be done if the OPTION is 'EQ'. So on trick is to store all the entries s_matnr-low in an internal table when OPTION is EQ & sign is I.

Then select the data from mara where matnr in s_matnr and store the data in another internal table.

Now compare the two, if the entry is there in select option but not in data retrieved from Mara U can display error message.

if not s_matnr[] is initial.

select single matnr into v_matnr from mara

where matnr in s_matnr.

if sy-subrc ne 0.

message e000 with 'Enter valid Material Number'.

leave list-processing.

endif.

endif.

Kindly reward points if it helps.
