In AOT you can’t set properties like help text for fields inside reference group . Is there any way to do that ? There is no way to override methods also over those fields.
You can change properties and override method of the reference group itself, but not those field generated by AX based on the currently selected ReplacementFieldGroup.
So if i have two fields inside reference group, i can’t set different help text for both
Of course you can and should, but you have to fix in the referenced table.
