Raising a long error message

Question

I need to raise the following error message.Following one is the message to be raised
“Error:  Combination of Document Currency [bkpf-waers], Local Currency [t001-waers], Group Currency [t000-mwaer] not allowed for transaction [bkpf-tcode].  Identical currencies should not be posted.”
other that "error: &1 &2 &3....."  Is there any way to do this.
if se91 long message alone is the only way in the sript editor how can we insert this message. Could anyone explain me this .
Thanks.

Answer 1

I do not think there is a way to pass variables dynamically to the long text in SE91. It is meant only for information purposes, and can hold static text only.
You could try the &1 &2 etc method, but even that has a maximum limit, I doubt you will get the entire line of text in it.
You could try calling a popup instead, to display the message.
Hope this helps.
