Unit JHR is not created in language EN

Dear All,

While creating billing document getting error 'Unit JHR is not created in language EN'. I checked all MM data, we did not update JHR unit for materials still we get error.

I checked JHR unit by using Transaction code 'CUNI'. JHR is available under dimension 'TIME'. JHR is available in data base tables T006 and T006A still system throws above error. Particularly for UOM 'JHR' getting above error.

Please provide the solution.

Thanks and Regards
