Foreign Trade Information Not Transferred from Sales Orders to Project Invoice Proposals in Project Management Accounting Module

Issue Description

In the Project Management Accounting module, when generating a project invoice proposal, the foreign trade information specified in the related sales order—including the Intercom and Registration Number fields—is not being transferred. As a result, sales orders that contain foreign trade data fail to carry over this regulatory information during invoice proposal creation.

Expected Outcome

The system should automatically transfer the foreign trade information (Intercom and Registration Number fields) from the sales order to the project invoice proposal. This ensures compliance with SAT regulations (Mexican tax authority) and prevents invoice rejection during the stamping process.
