Hi,
I need to add a new field to VendDocumentTableMap. I understood that it is not possible to create extension form maps and I need to use an Interface class. But i don't know how to bound the existing map with the new interface class.
Thank you
There is no interface class for this map as far as I know.
But you can work around the limitation by casting the map into the underlying table buffer in your code. This way you can access your custom field.
Here's an example with SalesPurchLine map.
if (salesPurchLine.TableId == tabeNum(SalesLine) { SalesLine salesLine = salesPurchLine; info(salesLine.MyField); }
Hi Gabi，
You cannot add fields to an existing map via extension.
Microsoft has implemented some mappings as interfaces, but not all classes have interface classes.
docs.microsoft.com/.../maps-as-interfaces
As mentioned, You can access your custom fields using the table buffer instead of your map.
if (_custVendInvoiceJour.TableId == tableNum(CustInvoiceJour)) { custInvoiceJour = CustInvoiceJour::findRecId(_custVendInvoiceJour.RecId); // Now you can access your custom fields of CustInvoiceJour }
