How to add CMK Attribute element to EDI Invoice

Summary:

We have an Inbound Invoice CMK integration. In the CMK message there is an element at the line level of the message (ATTRIBUTE1) that we would like to add to the Invoice as a reference attribute at the line level. The element already

shows on the Transformed message in CMK Messaging History, but we need to add this element into a field on the AP_INVOICE_LINES_INTERFACE (staging) table, that will then populate into the Invoice that gets built when the Import Invoices process runs.

UPDATE: I actually see that this invoice does get populated into AP_INVOICE_LINES_INTEFACE table, however we are not able to see this column on the invoice that is imported in Fusion. How do we make this visible in Fusion?
