We are in the midst of migrating to E10 and I am wondering how I can keep the screen customizations from E9 without re-creating all of them. Some are pretty complex.
The customizations won’t even load in developer mode to correct the script.
Go into the Customization Maintenance UI - not through the Developer mode - and load the Customization and then Select Verify from the Actions Menu. Do not use Force Verify.
Part of the Verification process is to change the code from E9 Syntax to ERP 10. It may not correct everything but it should fix up enough so you can work with the customization with the embedded tooling.
Do ERP conversion/verification process first. There will be some of forms/reports you need to manually fix them by changing the code or change UI layout (as Mr Rich said).
This is normal for debug customisation. There may be lot of error messages come up when loading the form in developer mode but you can go to the code by menu Tools>Customisation in the form.
Recompile the code and fix any error messages that come up in output
I also found Tools >custom xml editor is useful for fixing/deleting the missing parentcontrolkey issue.
