How to Show the Dimension if its excluded based on selection

[grajmca_sgp123]

Hi Every one ,I have requirement to show the Dimension value if its excluded based on  country selection.

TableA:

Country	Flag	CID
India	1	C_101
China	0	C_102
Asia	1	C_103
Bangladesh	0	C_104
Australia	1	C_105
Asia	1	C_106

TableB

Country	Flag	RID
India	1	R_101
China	1	R_102
Asia	1	R_103
Bangladesh	1	R_104
Australia	0	R_105
Srilanka	1	R_106

Script:

LOAD
Country,
Flag,
CID,
'Controls' as Indicator
FROM [lib://datasource/Sampledata.xlsx]
(ooxml, embedded labels, table is Sheet3)
where Flag=1 ; //Excluded China ,Bangladesh due to this filter
Concatenate
LOAD
Country,
Flag,
RID,
'Risks' as Indicator
FROM [lib://datasource/Sampledata.xlsx]
(ooxml, embedded labels, table is Sheet4)
where Flag=1 ;  //Excluded Australia due to this filter
I created table with dim as Indicator and exp :if(Indicator='Controls', Count(CID),Count(RID)).

For example if user select Asia we want to see  count by each indicator, here result is fine as we have country in both tables.

If user selects Bangladesh we can see count for Risk only.But he wants to see the other dim value(Control) and count as '0'.

Expected Output for Bangladesh  and same for other countries which are not in second table..
