Couldn't open ICX Application Message file

One off my team mate reported an issue while opening forms in Purchasing Super user he encountered error message:

"Message Dictionary couldn't open the ICX application message file. Cannot open file /u02/apps/apps_st/appl/icx/12.0.0/mesg/US.msb for reading."

When I checked the location it was not there. Then I though running generate message file from adadmin but it didn't help. Here is the solution :

We have run Concurrent request "Generate Messages" for "Oracle iProcurement" and it will generate US.msb file under required location.

Happy Troubleshooting !!!
