hi,

use

PARAMETERS : p_string type string VISIBLE LENGTH 127.

and in the at selection screen event.

check the string length the user has entered.

if strlen(p_string) > 127.

display error message.

endif.

There is a restriction on Characters type fields on Selection screen. It accepts only 132 Characters if declared as character.

Thats the reason for declaring it as STRING data type.

This will accept upto 255 Characters but i want to restrict it to 175 & Also i DONT WANT TO DISPLAY ERROR MEESAGE.

I Just want to restrict the input beyond 175 char.

Thanks,

Shawn.

Hi,

If you dont want to give the Error message then best option is to give a Hint in the selection screen by saying that it will accept only 175 characters.

Then at the at selection output

get the lenth of the parameter and then pass this to a another field of length 175.

Hope this might help you.

Hi,

I wonder how something is impossible to do!

I understand the other alternatives like giving a hint or error message but i wonder why SAP is limited to do something like this.

Anyways thanks for all who gave a thought about this.

Thanks.

Shawn.

What is the reason behind you wanting a 175 char parameter?
