Project Server User Security + Custom SSRS Reports Project List Parameter

Question

Hello, below is the issue / challenge scenario:
I'mnt. We have to remove the smaller chunk of queries that are hitting the published database to get the user security permissions. I'm using custom SSRS reports that are pulling data from Reporting database and other custom financial SQL DB's. I need to
figure out a solution to get the list of accessible projects for a particluar user using PSI. I did find this technet article that addresses my issue in a way
http : // technet . microsoft . com/en-us/office/ee862408(v=office.14).aspx#pj2007_ta_SecurityInReports_DevelopingThePsiProxiesClassLibrary
 the above solution means that I need to change many of my existing report queries (going to published DB)
Is there a simpler way to maintain a table that I can populate with the Project GUID's, name , user id, name using PSI? I can then refer the existing SQL's procs, TVF's to point to this table instaed of going to the published DB (unsupported method)
Any help/ direction is greatly appreciated
thanks,
SG

Hello,
The ReadProjectStatus PSI method defaults to Project for the Project Type, the value is 0. If you want other project types is gets slightly more complicated as you have to have multiple data sets for the ReadProjectStatus call, one for each project type
- each time specifying the default projType. For example for Projects (0) the query is:
<Query>
<Method Namespace="http://schemas.microsoft.com/office/project/server/webservices/Project/" Name="ReadProjectStatus">
<Parameters>
<Parameter Name="projType"><DefaultValue>0</DefaultValue></Parameter>
</Parameters>
</Method>
<SoapAction>http://schemas.microsoft.com/office/project/server/webservices/Project/ReadProjectStatus</SoapAction>
<ElementPath IgnoreNamespaces="true">ReadProjectStatusResponse/ReadProjectStatusResult/diffgram/ProjectDataSet/Project{PROJ_NAME,PROJ_UID,PROJ_TYPE}</ElementPath>
</Query>
For sub projects (5) it is:
<Query>
<Method Namespace="http://schemas.microsoft.com/office/project/server/webservices/Project/" Name="ReadProjectStatus">
<Parameters>
<Parameter Name="projType"><DefaultValue>5</DefaultValue></Parameter>
</Parameters>
</Method>
<SoapAction>http://schemas.microsoft.com/office/project/server/webservices/Project/ReadProjectStatus</SoapAction>
<ElementPath IgnoreNamespaces="true">ReadProjectStatusResponse/ReadProjectStatusResult/diffgram/ProjectDataSet/Project{PROJ_NAME,PROJ_UID,PROJ_TYPE}</ElementPath>
</Query>
You have to repeat this for all project types you want to include, create a hidden parameter for each project type then create a parameter to join them up and use the combined parameter to filter the data sets that get the data from the Reporting
database.
For other parameters in the ReadProjectStatus method see:
