How to automatic validity check in select screen

[Former Member]

Hi all

I was requested to set a fields like company code to select screen.

And designer tell me, if the company code input by user does not exist in T001, then SAP system can automatically display the error message.

How to do it if you donnot write a select sentence to check it?

select single bukrs from T001 into T001 where bukrs in s_bukrs.

parameters : p_bukrs like t001-bukrs.

at selection-screen.

if not p_bukrs is initial.
   select single bukrs from T001 into t001-bukrs where bukrs eq p_bukrs.
   if sy-subrc ne 0
   set cursor field 'P_BUKRS'.
   message e001(ZZ) with 'Please enter valid company code'.
  endif.
endif.

You cannot validate without writing a select statement.

[Former Member]

at selection-screen on p_bukrs.

select single * from T001 where bukrs = p_bukrs.

if sy-subrc ne 0.

message 'no co code is there' type 'E'.

endif.

start-of-selection.

Hello Jack,

U can do like this:

tables : T001.
 parameters: p_bukrs like t001-bukrs.
at selection-screen on P_Bukrs.
select single bukrs from T001 where bukrs eq p_bukrs.
if sy-subrc <> 0.
  <Error Message>
endif.

If useful reward.

Hi,

GOOD.

But SAP have given the provision to validate only by using select statement.

U need to check the entries in the table. Then only you can validate.

So you have to write the select statement for validation as others told.

Actually the domain for BUKRS has a value table ,

This has to check automatically when that field is used,

but when i see the documentation for value table , it says

<b>Value table</b>

In some cases you already know when you define a domain that all the

fields referring to this domain should be checked against a certain

table. This information can be stored in the domain by entering a value

table.

The system proposes the value table as check table when you try to

define a foreign key for this field. You can override this proposal.

<b> Entering a value table does not implement a check. The check against the

value table only takes place when a foreign key is defined.</b>

so in this case may be foreign key is not defined as the value table is same as T001
