Hi All,
I want to create "Add new address" option in a standard form as shown in the screenshot of SalesTable form, so in my extended table there is a custom "XXXCustomerAccount" and "XXXAddress" field which will be link, when user clicks on XXXCustomerAccount, the recId of postalAddress will be populated to XXXAddress field and we need to create a new address which will be link with that custom "XXXAddress" field.

Steps which I have done
1. I have created a new added a group like this in extended form, the screenshot is of SalesTable. The highlighted Menu Item Button is calling a display menu item and which is calling a class "DirPartyPostalAddressFormHandler"

2. Created a new menu item and called the same class "DirPartyPostalAddressFormHandler".
3. Now when trying to open this menuItem, I m getting this error -
"Error executing code: The field with ID '0' does not exist in table 'DirPartyMap'"
Please help me to resolve this problem.
Or if have any other solutions/way please let me know.
Thanks in advance!!!
