How to set data obligatory on matchcode ?

Former Member — Wed, 21 Jul 2010 09:16:53 GMT

Hello,

I create a Zmatchcode. It's run ok, the user can choose a parameters by search help...nice !!!

My problem is :

Now, I would that if the user don'use the matchcode and enter some random data on parameters an error message is showed.

I would that the user have only the possibility to entry data present on matchcode, and not other data.

How to do it ?

Tks.

Hi,

The Zmatchcode might be showing data from a particular table. In the AT-SELECTION SCREEN event, check using SELECT query whether the value entered in the parameter exists in the table or not.

In the At Selection Screen event you can write a select query to check whether the value exist in the respective table.After the select query check sy-subrc.If it is not equal to zero then the value doesn't exist.In that case u can use Message of type E to show an error .

Thanks!!
