Many organisations like to keep customer and location details current by subscribing to a third-party data source.
Shaded fields on any customer or location record come from a third-party.
The More page of the customer or location record displays the unique reference number or ID for each third-party record.
The data you receive from your third-party data provider will dictate what appears on some of the drop-down lists in the shaded fields.
In a validated system, whenever you make a change to any of these details a validation request will sent to the third-party company.
Important: The reference number cannot be changed. It will always relate to the customer or location directly. Typing over the current data with new will cause the change request to be rejected and the original data will be restored at the next data load overwriting your changes.
