1)    Start by navigating to Application Base Setup->Enterprise->Person->Person and search for the Person record. Then click on address and add a new address:

Enter the address details manually, the open map button only seems to open google maps, it can’t be used to select a location from the map as the address:

2)    Cloud only supports geocoding of location address so we need to create the map position via  Application Base Setup->Map Services->Basic Data->Map Positions manually using the following syntax:

ADDRESS_ID=youraddressid^PERSON_ID=yourperson^​

Make sure that LU name is PersonInfoAddress

3)    Navigate to Service->Scheduling->Basic Data->Scheduling Basic Data->Scheduling Resources and edit your scheduling resource to add the address start and end:

When you save make sure you don’t get a popup saying there is no map position connected.
 

Hope that helps,

Tom

This was improved in 22R2:

Create a person. Create an address for this person and activate Visit as an address type.

This will automatically create a location address entry and geocode the location.

Create a new service resource and select the address(es) created on the person record.
