Hi all, I am in desperate need of knowing how to extend the olap cube in project server 2007. I have been looking online however, I can only find information on extending the cube for project server 2003. I am fairly new to project server and our client would like to see information from specific fields when using data analysis. Im sure I didnt provide enough information however if any further information is needed please feel free to ask. If anyone could help I would really appreciate it.

Thanks in advance.

This is done through the PWA interface, in the Server Settings page-> Cube section -> Configuration link. There you will find a page allowing you to add dimensions and measures to the cubes at different levels. (The drop down labelled "Cube:" is the level to which things are added.)

Of course, the more you add to the cube, the longer the build will take. IT will also require more RAM and disk space. So after you change settings, watch the next build closely.

Thanks James. I have seen this however, the fields I want to add are the start and end dates of a projects well as an enterprise field we have created. I do not see these fields as part of the list box and I would like to add these fields to the MSP_Porfolio_Analyzer. Would "extending" the cube to include these fields be possible?

RE: start and end date
What sort of view is the customer trying to create with these fields? They are already there as the time dimensions essentially, and I'm not sure how good they would be as measures. (They certainly aren't additive, so you couldn't roll them up decently...)

My guess is that the view you are trying to create is better suited to Project Center or SQL Reporting Services.

Regarding the enterprise field you are trying to add:
From the last link included above:
Custom fields, in general:
Cannot be added as measures for the timephased cubes.
Cannot be added with formulas.

Dimensions:
Support only custom fields with lookup tables.
Support Flag custom fields, which cannot have a lookup table.

Task custom fields:
If the task custom field has a lookup table, it cannot roll up to summary tasks and cannot be used as a measure.

Measures:
Support only Cost, Duration, and Number custom fields. Those custom fields for Resource and Project entities, either with or without a lookup table, can be measures.

If a Cost, Duration, or Number custom field for a Task entity has a lookup table, it cannot be a measure.

If a Task custom field has a Sum rollup for task summary rows, it cannot be a measure.

Fields that have an Assignment roll-down and attributes set to None can be dimensions or measures.

Multivalue fields:
Cannot be included in the cubes because of a limitation in Analysis Services 2000.

Summary tasks:
The CBS does sum values of lookup tables for the summary tasks. However, if the lookup table does not include a value, Project Professional shows #Error for summary task rows.
So what are you trying to add? A dimension or a measure (Dimensions are on the sides of the OLAP view, measures go into the table.
And what kind of Enterprise custom field are you trying to add?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Well the customer would like to add the start date and end date of a project to the MSP_Porfolio_Analyzer cube so that it could be reported when using excel services. I see what you mean when you say the time dimension is there. I will continue to work with excel services to find out how to incorporate the Time dimension.

With regards with the custom field, it is a dimension I am trying to add however, it does have a formula. The formula just concatenates three other fields, two with lookup tables and one which is just text. I will continue to play with these as well and come back if I have any further questions. I'm sure I will.

Thanks a lot James, I appreciate all of you help.

James would by any chance know of any good articles or documentation on using excel services or reporting services for reporting on Project Server 2007?

Thanks

I haven't used Excel Services much, but I do a fair bit of report development for SSRS.
The ProjectServer_Reporting database is pretty easy to use, and many tables have equivelent views, such as MSP_EPMTasks_UserView, which include Custom fields.
