Nothing to Worry

Delete and Re-create at least 3 times 

before you give up ...

Go for a tea-break or lunch

when you come back

it will be fine ...

else 

If you have friends on SAP

Ask them

Else

Start Gooling

It may or may not help

But that could be the only source

Try SCN OSS Notes 

Try them all

Go home if it's already late

wait for tomorrow

not much point to worry about it

when tomorrow you go to work

Start on a clean sheet of paper

Think outside the box

Ask the customer or user 

To trace every step they did 

that ended with

the error

And simulate those steps yourself 

If

if it still does not work yet,

Still 

There is nothing to worry about

Get Development to debug

Still not working

No worries 

Its just a piece of Software
