Ok,
You want to multiply account Nominal Count for each Employee, Int Order, Cost Center, Time by some rate stored in Employee "NONE", Account "Personal Cost", Internal Order "IO_NONE" and corresponding Cost Center and Time.
For DM package the script will be:
//Scope for the script from DM SELECTION
*XDIM_MEMBERSET TIME=%TIME_SET%
*XDIM_MEMBERSET INTORDER=%INTORDER_SET%
*XDIM_MEMBERSET EMPLOYEE=%EMPLOYEE_SET%
*XDIM_MEMBERSET COSTCENTER=%COSTCENTER_SET%
*XDIM_MEMBERSET ACCOUNT=NOMINALCOUNT
*WHEN ACCOUNT
*IS * //scoped to NOMINALCOUNT
*REC(EXPRESSION=%VALUE%*([ACCOUNT].[PERSONALCOST],[EMPLOYEE].[NONE],[INTORDER].[IO_NONE]),ACCOUNT="PERSONALCOST")
*ENDWHEN
