Popup in RF device by LM01

Dear Experts,

I was creating an LM01 custom transaction waherin i called FM for TO creation.

but while testing I found that there are some enhancements done in the FM which calls an information message on screen.

in normal scenario it's OK while testing on PC. but what would be it's behavior on RF scanner as we don't have scanner to test in development system at offshore..

I tried to search on SDN and found that some people are saying that popup do appear but OK button did not work.

Has any one scene such scenario before or what could be possible solution for this.

Thanks a lot!!
