WEBI : seems to be a problem (or bug) in providing a multi selection Input control to users when linked to variables

Environment: Web Intelligence Desktop (Version: 4.1 Support Pack 5 Patch 6)

Objective: to get the percentage values based on user Input controls and variables.

Issue: Seems to be a problem (or bug) in providing a multi selection input control to users when linked to variables.

Input Controls:

1. Category - Single selection
2. Reporting State Name - Ability to select All or Multi or Single
3. Manufacturer - Ability to select All or Multi or Single
4. Pack Size - Ability to select All or Multi or Single

Sample screen of the report (see description of the issues after this screenshot)

1. Table-1 - Displaying volume numbers based on Input Control selection - No Issues
2. Table-2 - Displaying the Percentage numbers based on Input Control selection and Formula
   1. Formula Name: Man % MAT
   2. Formula: (Sum([Last 12 Months].[EOS Volume])ForEach([Manufacturer])/Sum([Last 12 Months].[EOS Volume])ForAll([Manufacturer])*100)
   3. Works when "All Values" selected for input control "Manufacturer" (see below)
   4. Issue: But when single value (Example M-ABC) selected for Input Control Manufacturer, the percentages are incorrectly displaying as 100% (see below)
3. Table-3 - Displaying the Percentage numbers based on Input Control selection and Formula
   1. Formula Name: Man % MAT 2
   2. Formula: NoFilter(Sum([Last 12 Months].[EOS Volume])ForEach([Manufacturer])/Sum([Last 12 Months].[EOS Volume])ForAll([Manufacturer])*100)Where([Category]=ReportFilter([Category]) And [Last 12 Months].[State Name]=ReportFilter([Reporting State Name]))
   3. Does work only when single value is selected for "Reporting State Name" (see below)
   5. Issue: Does not work when "All Values" (or more than 1 value) selected for "Reporting State Name" (return blank cells, see below)
4. Table-4 - Displaying the Percentage numbers based on Input Control selection and Formula
   1. Formula Name: Man % MAT 3
   2. Formula: (Sum([Last 12 Months].[EOS Volume])ForEach([Manufacturer])/NoFilter(Sum([Last 12 Months].[EOS Volume])ForAll([Manufacturer]))*100)
   3. Issue: Percentages numbers are not correct (NoFilter function seems to be applied incorrectly, see below)

with all the scenarios we are unable to use multi selection with user input control.
