AutoLookup ItemName? just like how it works on OffsetLedgerDimension

I’m working on a form customization right now, on the PurchTable form. As part of this customization, I want to (retrieve / auto lookup) any values that the user has typed into the ItemName field; just like how it works on LedgerJournalTrans.OffsetLedgerDimension.

Any help would be appreciated. Thanks!

You could create a relation, overwrite the lookup() method and so on, but isn’t ItemName based on a display method (maybe it isn’t in your version of AX)?

Why do you need a lookup for itemName?
