SSAP to MSAG Synchronization

The SSAP Site Structure Address Point to MSAG Synchronization quality control (QC Quality Control) check compares address points to the Master Street Address Guide (MSAG) to see if any addresses in the Site/Structure Address Points (SSAP) data are not present in the MSAG.

Note: Synchronization QC checks can have leading zeros in the Emergency Service Number (ESN Emergency Service Number. A three to five digit number representing a unique combination of emergency service agencies (law enforcement, fire and emergency medical service) designated to serve a specific range of addresses within a particular geographical area, or Emergency Service Zone (ESZ). The ESN facilitates selective routing and selective transfer, if required, to the appropriate PSAP and dispatching of the proper service agency(ies).) fields for any of the layers or tables used in the QC check. The leading zeros will not negatively affect the comparison and an accurate fallout for the synchronization check is created, including accurately displaying your data with any leading zeros.

Note: For all field comparisons, null and empty/blank values are considered equal values. This includes ESN, Community, and street name field comparisons. For example, in SSAP to MSAG Synchronization, if an address point and its associated MSAG have an ESN of null and blank respectively, this will not cause a fallout as neither record contains an ESN. To create a fallout for a required field when it does not contain a value, utilize the Null Value in Field check.

Note: Leading or trailing spaces will not be trimmed in any fields used for comparison. To fix issues caused by such spaces, remove the extra space in your source data.
