ASO - data copy from current Year to prior year

Content

We need to copy data from current year to prior year in Essbase ASO cube (essbase 11.1.2.4)... below are the options we tried

1) create a report script to export current year data, then a rule to load in, and then a MAXL to combine these two.... but the EXPORT takes a lot of time... not good approach

2) we followed the link - Hyperion Essbase: Data Copy in ASO Applications using calculation script  and as we add all the level 0 members in cross join in MAX, then there is error..
