Dear All,

I created new Domain on DEV server and I did Convert to Runtime Data Dictionary already. I use this Domain on the Form Definition of the session for get the value via LN UI. On DEV it's fine working.

After that I exported the solutions of them and installed on another server. Then I also did Convert to Runtime Data Dictionary and I try to start the session I got error message as below;

Process 394 - Error : [MR_UNK_DOMN] f.line.option field has an unknown domain: 'txxxx.lopt' (gfd.read.dump2() in object ottstpstandard)
Process 394 - Fatal Error : [MR_UNK_TYPE] Unknown 'f.line.option' flag 0
Process 394 - Fatal Error : Can not continue in txxxx1400m200 in DLL: ottstpstandard (gfd.read.dump2)[read.fast.form]

How can I solve this error? Please you advise, It is appreciated.

Try
1. Convert All.
or
2. Delete the Domain and recreate it manually then convert it again.
Make sure you backup before doing any changes though.

Hi Tmannais,

Thanks for your advices. I restart LN, It's working fine.

Regards,
Aris.
