[Payables Agent] set Document Date and Due Date on Incomming Document when Draft is created

[Explorer986]

What & why

When an inbound E-Document is imported, the Prepare draft step already fills in the vendor name and number from the E-Document Purchase Header. But it was not filling in the Document Date and Due Date.

Because of this, once a document reached the Draft ready status, the Document Date and Due Date columns showed up empty on the Inbound E-Documents list, even though those values were already present on the E-Document Purchase Header.

This fix copies the Document Date and Due Date from the E-Document Purchase Header onto the E-Document during the Prepare draft step. It only copies them when they actually have a value, so an existing date is never replaced with a blank one. This is the same approach already used for the vendor name and number. Now both dates show correctly on the Inbound E-Documents list once the document reaches Draft ready.

How I validated this

• I read the full diff and it contains only changes I intended.
• I built the affected app locally with no new analyzer warnings.
• I ran the change in Business Central and confirmed it behaves as expected.
• I added or updated tests for the new behavior, or explained below why none are needed.

What I tested and the outcome

I imported an inbound purchase E-Document and processed it until it reached the Draft ready status. The Document Date and Due Date then showed up correctly on the Inbound E-Documents list and matched the values on the E-Document Purchase Header.

I also checked the case where the E-Document Purchase Header has no date set. In that case the existing values on the E-Document were left as they were and did not get overwritten with a blank date.

I confirmed that the vendor name and number still resolve the same way as before.

Risk & compatibility

Low risk. The change only fills in two extra fields, Document Date and Due Date, during the existing Prepare draft step, and it does so only when a value is present. There are no schema changes, no permission changes, and no impact on the Version 1.0 import path.
