ExecuteCustomCalculateBusinessRule ... but in workspaces

Hi,

I came across an update function in the business rules for ExecuteCustomCalculateBusinessRule

Previous function (still in use) : BRApi.Finance.Calculate.ExecuteCustomCalculateBusinessRule(si, brName, functionName, nameValuePairs, timeType)

New function for workspaces : BRApi.Finance.Calculate.ExecuteCustomCalculateBusinessRule(si, workspaceID, brName, functionName, nameValuePairs, timeType)

We can indeed at least in version 8.5 create Finance Custom Calculate Services :

However, these don't use any business rule name, hence my confusion ? How do we execute a custom calculate service which is currently within my workspace assembly services ? Or should it be used in a different way ?

Regards,
