Datetime entry for querying analysis service cube

Hi everybody,

I have two problems while using a analysis service cube as data source for a reporting service report.

1.) I've an individual time dimension which has day entries in the standard date format "mm/dd/yyyy". When using an parametric entry for the date hierachy the reporting offers me all entries as a list (some 1000 entries). Looking under report parameters I recognized that the input parameter is listed as of the type string. However I know that the underlying field and as well the hierachy in the cube is of the format datetime. Change it to datetime causes the reporting service to fail with the error message:

An error occured during local report processing.
The property 'ValidValues' of report parameter 'DIM...' doesn't have the expected type.

How can I use the parameter in the format datetime to restrict the time dimension? ...so that I can select the date over the calendar function.

2.) I have another dimension with the hierachy cycle which has the string format "year-month". I would like to use the selection of the date hierachy to create the restriction on the cycle hierachy. I.e. entering '01/16/2007' on the time dimension should write the value '2007-01' to a parameter which is then used to restrict the cycle hierachy. Experimenting with report parameters always caused the error message:

An error occured during local report processing.
An error has occured during report processing.
Query execution failed for data set 'DIM...'.
Query (1,453) The restriction by the CONSTRAINED-flag in the STRTOSET-function has been violated.

As I only allow single value entries I thought about changing the STRTOSET command in the underlying MDX query into STRTOMEMBER. However this didn't solve the problem.

How can I create an input for a restriction on a dimension based on a parameter with a self constructed string?

Thanks,

Each member in your Time dimension is identified using the following format [DimensionName].[AttributeHierarchyName].&[MemberKey]. This is the format that the generated parameter query uses. You can use this format to apply a fiter and limit the members shown. The Report Builder could help you to understand how to set the filter. Alternatively, you can set the Value property of the Date dimension key to the underlying field of DateTime type. However, each SSRS parameter can have only two values (label and value). To pass the selected value to the main query you need to resolve it to a valid member (again [DimensionName].[AttributeHierarchyName].&[MemberKey]). So, it may be more convenient to stick to this format as the parameter value.

|||Thanks this was of help ...even so I don't like the idea of constructing the member representation of the analysis service but it works |||can you tell me exactly how you resolved this? thanks,
