We had a custom extension with custom fields in Sales Invoice Line. However during an upgrade it got accidentally deleted. We are trying to repopulate, however Business Central is throwing error saying Posted Sales Invoice is /locked/ and modifications are not allowed. We are only making changes to the custom fields used by the custom extension.
What are some options to repopulate the custom fields for a Sales Invoice Line in Posted Sales Invoice?
