BPC 10: Time version of dimension ..... does not exist

Hi Experts,

I am trying to load a simple Hierarchy from SAP BW 7.3 to SAP BPC 10.0 (with Package: Import Master Data Hierarchies from BW InfoObject). The Loading of Master Data Text/Attributes was successful. Validate & Process Transformation File for the Hierarchy Load is also running successfully. After running the package I receive the error message:

Time version of dimension RB_ACCOUNT does not exist

Thanks for your replies
