CrossItem causes invalid Id error - acumatica

Question

I have had added CrossItem attribute to the InventoryID field in Appointments page. But, this caused inventory id invalid cast issue.
This is how I have added the attribute to the property.
And here is the stack trace of it.

Error: An error occurred during processing of the field Inventory ID : Specified cast is not valid..
System.InvalidCastException: Specified cast is not valid.

I have had the same issue in Service Orders page too. How do I resolve this issue?
Thanks.

This error happens because of duplicated attributes on the InventoryID field: the Append to Original option will always append the list of original attributes with your custom ones.
The error should be resolved after you switch to the Replace Original option, as shown in the screenshot below:
