hi
In Business Central, when a purchase order is created from a sales order, a link is established between the two documents through the Cross-Reference feature. This allows you to easily track the related sales order when viewing the purchase order, even after both documents have been posted.
To view the related sales order from a posted purchase order, follow these steps:
Open the Purchase Order in question.
Go to the "Navigate" tab on the ribbon, and click on "Cross-Reference".
In the Cross-Reference window, select "Sales Header" in the "Referenced By" field.
This will show you a list of all the sales orders that have been referenced by this purchase order. You can then select the relevant sales order and click "Open" to view it.
Alternatively, you can also use the "Document Relationship" feature in Business Central to view the relationship between the sales order and the purchase order. This can be accessed from either the sales order or the purchase order, by clicking on "Document Relationship" in the "Navigate" tab on the ribbon. This will show you a graphical representation of the relationship between the two documents, and allow you to easily navigate between them.
