I'm not sure what you are really asking. Can you give us an example?

Means if we are showing an error messaage like "Date needs to be entered After &date.A future dated transaction exist on this date."
Suppose this message is stored in message catalog With no &date can we print the &date value also along with that message.

Your message should be stored as ""Date needs to be entered After %1. A future dated transaction exist on this date."
You can then pass the date value when you call the message. If &date value is "none" and you want to send "&date" instead, then you can write an if statement to check for the value before you call your message.

if none(&date) then
/*call message catalog and pass a constant value to it, like '&date'*/
else
/*call your message and pass the actual date value, like &date*/
end-if;

Your question still doesn't make much sense to me, may be because i'm still not sure what you are trying to do.
