Hi all !
In Dynamics NAV you can attach a link (pdf, image…) to a specific record, such as a Posted Sales Invoiced:
The system saves the address and name of the document associated, so if you delete or rename it, or if you move the document to another place, you will find the following error message next time you try to open the link:
Link address is not valid.
You can delete a link if the IT administrator has assigned the necessary user permissions to you.
If a user deletes a single record then all the links attached to the record are deleted. However, if you delete records using a batch job, such as the "Delete Invoiced Sales Orders batch job", then the links are still stored in the Record Link table. To delete the links from the database, run the "Delete Orphaned Record Links" codeunit.
Have a nice day !
