Space in Source Field names creating dataload failure

Dear Experts ,

We are trying to extract data from MS Analysis Service Cubes using UD connect .The source field names of the MS cube contains spaces. E.g.

1> Employee Name As In Passport

2> Employee State As in Passport

3> Weekly Salary

4> Monthly Salary

etc ...

While creating datasource , the field name automatically concatenates without spaces e.g. EmployeeNameAsInPassport and hence while trying to extract data it says EmployeeNameAsInPassport can not be found in source system .

Any pointers on how to allow spaces in datasource field names and if its not possible then any suggestion on the workaround so that the dataload can be successful ?

NOTE : It is not possible to remove the spaces in the source system field names as it will impact whole source system design. Workaround needed at BW side.

Thanks

Samir
