Hii,
I have a requirement to save additional information when invoicing Sales Order for the purpose of Invoice Acknowledgement.
There are 20 new custom fields that need to be saved when invoicing SO to the CustInvoiceJour table.
So I decided for to add an extension/child table under CustInvoiceJour and save the new additional information in it from sales table.
I followed this article to add extension table http://daxonline.org/9-table-extension-framework.html
In this article step 6. Create/Update methods at parent table, I am getting following error.
The operand is not compatible with the type of the method?

Extension Table: CustInvoiceJour_Ext
I did restart, AOS, Sql Server, Incremental CIL, Full CIL but still getting the error.
Should I achieve it with extension table or just save values somewhere when creating invoice?
Thanks,
