Vantage 8.03.405 - Customization Quirk

I have made a customization to the Job Entry - Material Tab: added
ud field. Works fine.

However, the customization does not appear when I access the
material form via the purchase order screen by right clicking on the
material sequence field on the line tab and selecting the add menu
option.

So I made customization to the material form via the path above. I
just can't get it to stick.

Created a process calling maintenance entry. Now my customization to
the material form appears via the PO entry; however, I lost the
customizatin via the Job Entry.

The process key is Epicor.mgg.ui.jobentry
The calling app is Epicor.mfg.ui.poentry
The menu id is JCGO3001.

I have been in touch with support, but thought I would try the
group. Support told me these were two different forms; which I
believe, but the menu id is the same.

Any help would be appreciated...Thanks Clinton
