Hi,
The aim of this case is to figure out how to save a field in the endpoint so that, when I import the customization project, this new field will be available for use. I need to add OrderNbr for PurchaseReceipt.

After I added the field to the endpoint, I pressed Validate Entity. Then, in the customization project, I selected my package and pressed Reload from Database.

After that, I selected Publish with Cleanup and exported my customization package.

During testing, I imported my customization project, but the OrderNbr field was not available in the endpoint.

Acumatica 2026R1. I tried without reloading from the database and publishing with cleanup, but result remains the same
