Hello Percy,

I can see from the stack that the standard source TRTACHFAC1 is compiled under the production folder instead of existing only in X3 folder. This happens when: A patch was installed incorrectly (production folder instead of X3 folder) or a developer compiled the standard code for customizations.

Check if the standard code has customizations and try to "migrate" them in a way they work with the standard source file. Try using entry points or encapsulating code instead of overwritting standard code or updates may cause this type of problems.

Solution: Backup and remove the source/.adx file in OBSLIV\TRT folder (rename the file to start with "_" for example). Restart the session after. I am assuming that under X3\TRT folder, a valid TRTACHFAC1.adx for the V12 exists.

Regards.

I had the same issue before, its exactly what you said. The TRTACHFAC1.adx was incorrectly compiled in the child folder, renaming/removing it from the child folder solved the issue.

Thanks this solution worked for us
