Question about dataasource and the .rdl file and the .rdl.data

Hi !

Maybe the only one who can answer this question is people from Microsoft but if someone have an idea just tell me ^_^ i really need a solution.

We have over 500 Access reports. I have imported all those reports but since there is some difference between Access and reportServer we have to make some changes on the reports.

Since i'll be too long to change all the reports one by one. I've created un program in .NET that open all the .rdl file. Those files are in XML so it's pretty easy to change all the things that doesn't work in ReportServer. So i've tried my program and everything is working fine except for the DataSource. When i look at the tag DataSource generated in the .rdl it seems that when we databind the report with the datasource it adds a Unique DataSource ID and also a new file .rdl.data
I've binded 2 reports with the same datasource and notice that the datasource ID is always different.

What i want to know is since all our report will use the same datasource (Shared). Can i use the same datasource ID for all the report and just copy one of those .rdl.date files for each report ?

I really need an answer because i'm afraid to have to changed all those reports one by one -_-

Thank a lot and Sorry about my english.

If the data sources are all the same, you can use a single shared data source.

The rdl.data file is used only by Report Designer. When you go live and publish the reports, you will not need the rdl.data files to view the reports. If you are using Access as the data source , you will need to have a path to the file all users can reach.

|||Thank for your answer!

I have already declare a shared datasource in our reportServer project. My problem is when i imported our access report in reportsercer the datasource set in the report is not the shared datasource. So i've tried to change in the XML code the tDatasource tag to bind our shared datasource but it doesn't work because i don't have an ID (i think).
I tried to bind 2 reports using visual studio to the shared datasource and notice that when you bind the report to the datasource a Datasource ID is added to the xml file. It seems that this ID is unique (Something like c5wcw-6fjhwj3-dwqw-ds2d2). So can i use the same id for all my reports?
|||I took a look at my current sub-project, 3 of 4 reports had exactly the same ID for the shared Datasource and one had another ID, so I copied the ID of the 3 others into that rdl and everything was still working.. I don't know how MS generates that IDs and what they are good for, but it seems you can use the same ID in all reports.. In my case neither the ID of the 3reports nor the ID for the last report matched the ID in the rds-File for the Datasource, so
just try to use the same <Datasources>...</Datasources> for all Reports..
