select LIFNR

from LFB1

into table

where lifnr in s_lifnr.

if sy-subrc ne 0.

message e888(sabapdocu) with 'no number found'.

endif.

in this way u can write the select query.

Hi Try this format..

Ex:

selection-screen begin of block b1.

parameters: p_datum1 type sy-datum,

p_datum2 type sy-datum.

selection-screen end of block b1.

at selection-screen on block b1.

if p_datum1 is initial

and p_datum2 is initial.

message e001(00) with 'Enter at least one date'.

endif.

in se91 T-Code you can create message and that number you can use after

Message

command.

let s_vendor and s_burks be those 2 sel-options

tables: lfa1,t001.

at selection-SCREEN on s_vendor.
select * from lfa1 where lifnr = s_vendor.
if sy-subrc is not initial.
message.................
endif.

at selection-SCREEN on s_burks.
select * from t001 where burks = s_burks.
if sy-subrc is not initial.
message.................
endif.

Hi Dude,

You should use the AT SELECTION-SCREEN event.

AT SELECTION-SCREEN.

if s_lifnr not in ('0001',.......).

message E100 with s_lifnr.

endif.

if s_bukrs not in ('1000',....).

message E101 with s_bukrs.

endif.

select * from lfb1

into table it_lfb1

where lifnr = s_lifnr and

bukrs = s_bukrs.

if sy-subrc <> 0.

MESSAGE I102 with s_lifnr s_bukrs.

endif.

see these validations check for the value to be in a specific

set of alternatives.If the values' attributes doesn't match the

variables' attributes then the system will automaticlly generate a message.

To issue messages you shoud add the message-class addition to the report statement as below,

report zxxxxxxxx message-class zmsgxxx.

double click on the zmsgxxx and

write messages as

msg-no desc.,

100 & not a valid vendor

101 & not a valid company code

102 No records found for vendor & and company

code &.

The ampersands are place holders for values.

They are specified at run-time with the 'WITH' addition.

eg., with s_lifnr.

the E & I before the message nos denote the message types

which decided the time or place of message issual.

If any clearance needed please share it.
