When I run the report I am getting data for 3years I would like to include a filter to fetch only previous year data in this case data. The measure that is mentioned here should have data only up to the current Year. I have tried this way as well in slicer member set: set prevmember item tail filter members [Employee expense]. Could you please help me how and where to use this filter to get the exact result in report page. Drag a query calculation from the tollbox and give the propery hierarchy and select the option 'Set Expression' and give the below Expression.

In theory, time calculations are simple; however the DMR dimensional model relational data I was working with last week was presenting a challenge to create Cognos BI PY calculation. DMR is a modeling technique in Framework Manager that identifies predefined hierarchies in relational data; hence providing a pseudo dimensional view of the data.
This allows end users to drill-up and down through aggregate levels of data. In an OLAP environment, you point the system to an intersection by selecting multiple dimensions. DMR in Framework Manager uses filters and aggregations to build hierarchies in relational data. The second data nuance in this particular data set was that versions and measures were combined as a single fact.
This did not create any issues. It just needed to be taken into consideration while developing the reporting strategy. Since DMR is relational data, end users must select an associated reporting period and fiscal period. To eliminate the error of mixing and matching unassociated years and periods, a tree prompt was used with instructions to the end user to select a reporting period. This forced the end users to select a period from the fiscal year on which they wanted to report.
Before the tree prompt was built, a current year parameter was created using a data item in the tool box. This is a crucial step if you are going to use a prompt in parallel period or a cousin function. Once you have your current year prompt established, select a calculated member from the tool box to build your Cognos BI PY calculation and follow the calculation listed below.

Welcome, Guest. Please login or register. Did you miss your activation email? The problem is that when i write the function in the expression editor and run the test button only for the query item it gives me output without error, however as soon as I go and publish the package I get some error. This object is a 'hierarchy', which is invalid for this type of reference.
