Hi Sam, this means the Sage Database ID. The name of your actual sql database can be more than 3 digits. Your Sage300 database needs to use a 3 digit database ID that is the same 3 digit ID used by your employer code in HRMS. A good example is the out of the box sample company created by HRMS. The actual sql database name is SageHRMS_DEU but the employer code and Sage Databse ID are just DEU.
