How to verify ... variable input

Question

To whom it may concern,
I am referring to this SAP document which suggest that we can verify
the variable entry with a message pop up.
1- How To ... Verify Variable Input.pdf SAP Document 
Another BW Expert Online document talks about the same solution
2 - "Add Pop-Up Messages to BEx Queries for Simple Validation and Feedback "
I have tried to implement these solutions, but they do not seem to work as they were printed.  I have been in communication with SAP and they have indicated the same.
I have found a number of items not to work:
1) The RAISE again statement gives an error when the project is
activated
2) The variable. Should this not be Customer Exit. IN the picture it
is indicated as user entry.
3) This does not seem to work in the web. Only in the BEx Analyzer.
Do you have any solutions that work in the web.
Basically, what I am trying to implement a solution that checks the variable input
entry before executing the query via the web.
Thank you.

PS For anyone who is interested in the code that i have used:
I have looked at the Online help , (the second one)
when i put as mentioned RAISE no_processing, then this is the error that comes up:
"NO_PROCESSING" is not defined as an exception in the function module.
Here is my Code:

Hi San!
Are you able to send me a working copy of one of your bits of code.
Thank you for you analysis.  Still some issues however,  and there are some debugging issues:
If you can further assist, here is the design of our query:
-  i have the following user entry variables ZS_VTYP1, ZS_VTYP2 and ZS_VTYP3 for the characteristice 0VTYPE - Value Type.
-  i have the following user entry variables ZS_VTYP1, ZS_VTYP2 and ZS_VTYP3 for the characteristic 0VERSION - Version.
If you put value type 60 (Forecast) in any or all of the value type user entry variables, then you must put a corresponding version identifier, eg. F1
Hence this is where the message that is required.
Otherwise, if Value type 10, or 20 Actual or Plan is entered, then it is fine.
I have put tabs in the code you sent me, but it seems to debug
with these 2 messages:
WHEN is only allowed after case
="... " Expected after RAISE
I have tried to interperet your logic here:
WHEN is only allowed after case
="... " Expected after RAISE

1) Verification of input variable is done in I_STEP = 3.
2) I_STEP =2 is called for all variable(Customer exit type).
3) i_STEP =3 is called only once for all variable.
1) The RAISE again statement gives an error when the project is
activated---Your Activate..that is not problem..go ahead with that.
2) Variable can be Customer exit..i have done this...
3) It work in Web also..
ZS_VTYP3 is a user-entry varibale and ZS_VERC3 is customer exit
variable.
