In addition to the standard fields, additional fields are added to the account object in the Spoke Org.
When you install the unmanaged package on a Spoke Org, the package adds the following fields to the account object:
MultiOrg Last Update From Master
Stores the timestamp of the last update from the Master Org to an account or person account in the Spoke Org. For example, this field shows that the last update from the Master Org is 3.00 P.M and a user opens an account at 3.45 P.M in the Spoke Org. The list of fields that are updated in the Master Org after the 3.00 P.M for that account appear on the page. The value for this field changes from 3.00 P.M to 3.45 P.M.
MultiOrg Batch Run Number
Stores the run number of a batch job. Separate batch jobs are available for synchronizing accounts and person accounts with the Master Org.
