Check calculation period of Subset Data.Filter

Problem: When an user executes an Excel-Subset with a Data.Filter and this Data.Filter has unsufficient restrictions on every dimension, then the subset calculation will need a high amount of Server resources and the olap service is likely to crash. Reason: User don't realise, how much resources the calculation might take or User are fast inserting a subset without checking the restrictions of the data.filter. Solution: Before executing a Subset with a Data.Filter check the estimated amount of resources for the calculation. If the amount is to high: display a warning for the user. If he clicks "yes" then the calculation will proceed. If "no", then the Data.Filter will be not included into the subset and no calculation will happen.
