3771239 - Error "Unit of measure must be convertible to activity type UoM" when creating service cost rates for activity type SAP S/4HANA Cloud Public Edition.

Error "Unit of measure must be convertible to activity type UoM" is seen when creating and saving a cost rate in app Manage Cost Rate - Services for an activity type.

SAP S/4HANA Cloud Public Edition

1. Open the app Manage Cost Rate - Services.
2. Add a cost rate with an activity type.
3. Choose Save
4. Observe that the system shows “Unit of measure must be convertible to activity type UoM”.

The activity type is maintained with a different unit of measurement (UoM) than what is selected in the Service Cost Rate. 
For example, the Activity Type A is maintained with UoM as Piece (PC), as seen in app Manage Activity Type. However, the Service Cost Rate being created is using UoM as Hour (H).

Change either the UoM of the activity type or the cost rate so that they are consistent. Also, only Unit of Measure "H" should be used in Professional Services when setting up activity types.
