OLAP universe query filters using multiple key values

Question

Hi,
We are running BO over a MSAS 2005 cube and due to reporting requirements we have had to split the year out from the standard time hierarchy so we have it as a separate hierarchy from the rest of the time hierarchy. We also have 2 other dimension objects we use to find the current reporting month (shown below as Current Month and Current Year) which link to the Year and Month dimensions to give us the current year and current month.
I have created predefined filters in the universe for Last Month and Last 6 Months etc which link the 2 hierarchies together to dynamically find the correct months to pull out based on the current reporting month.
The issue i am facing is that when these filters are used in reports we are not able to pull through the Year dimension in the report as we receive the error: "The Year Hierarchy hierarchy is used more than once in the Crossjoin function"
We can however use the Month dimension in reports even though it is also referenced in the filter definition.
I have narrowed the issue down to the fact the Month dimension is mentioned in the Filter Key which allows it to be used in the reports.
Is it possible to include 2 key values or are there any other ideas on how to tackle this problem so i can include the both the year and month in reports using these filters?
Last Month filter:
<FILTER KEY="@Select(Period To Date\Month).[TECH_NAME]"><CONDITION OPERATORCONDITION="InList"><CONSTANT TECH_NAME="CASE WHEN FILTER(@Select(Period To Date\Month).Members,@Select(Period To Date\Current Month).[Y]).Item(0)= @Select(Period To Date\Month).[January] THEN {CrossJoin(FILTER(@Select(Period To Date\Month).Members,@Select(Period To Date\Current Month).[Y]).Item(0).lead(11),FILTER(@Select(Period To Date\Year).Members,@Select(Period To Date\Current Year).[Y]).Item(0).lag(1))} ELSE CrossJoin(FILTER(@Select(Period To Date\Month).Members,@Select(Period To Date\Current Month).[Y]).Item(0).lag(1),FILTER(@Select(Period To Date\Year).Members,@Select(Period To Date\Current Year).[Y]).Item(0)) END"></CONSTANT></CONDITION></FILTER>
Thanks in advance

Dear Daniel, may I ask one more question please?
what if I have 4 tables?
table1
ID * ID_Type_code * Name
0001 * 11 * abc
0002 * 12 * abcd
0003 * 13 * abcde
table2
ID * OID_type_code * Name
0001 * 22 * abc
0002 * 23 * abcd
0002 * 25 * abcd
0003 * 23 * abcde
0003 * 22 * abcde
0003 * 28 * abcde
table3
ID * OID_type_code * OGAD_line_id * address
0001 * 22 * 1 * a street
0001 * 22 * 2 * b street
0002 * 23 * 1 * c street
0002 * 25 * 1 * d street
0003 * 28 * 1 * e street
0003 * 28 * 2 * f street
0003 * 28 * 3 * g street
table 4
ID OID_type_codeOGAD_line_id*COP_line_id*phone number
0001*22*1*1*2222222222
0001*22*1*2*3333333333
0002*23*1*1*4444444444
0003*28*2*1*5555555555
0003*28*2*2*6666666666
Primary key for each table
table1, primary key is ID
table2, primary key is ID , OID_type_code
table3, primary key is ID , OID_type_code, OGAD_line_id
table4, primary key is ID , OID_type_code, OGAD_line_id , COP_line_id
I would like to show each value in each table in the separate input text fields.
Therefore, this is an advanced question based on the previous one, not only get values from one table but also from several tables based on input for example 0003 and 28 as the ID and OID_type_code?.
Let me know if you need more details,
Thank you so much,
Viola
