I am running into the Maximum Request length exceeded error on one of my SSRS reports - SQL Server 2005 SP2. I modified my web.config file as described in this and other threads: http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/31a74097-28cc-4f29-9397-fdeda1cca994 I restarted all services (IIS, Reporting services) and while it fixes the problem with the parameter, I am getting other errors that are preventing the report from rendering as expected. For example, I have a document map in the report which no longer displays, and expand/collapse capability in the report doesn't work. Any other ideas for fixing this issue?

Hi N.Edmonds, Currently, it seem that your issue is that expand/collapse capability does not work in the document map. I think there might be some relationships with your steps for creating the document map function. So here I would recommend you follow these steps to reproduce the document map function to see whether it works, if not please give some some feedback: To add a report item to a document map 1. In Design view, make sure the Properties pane is visible. Click the report item such as a table, matrix, or gauge that you want to add to the document map. The report item properties appear in the Properties pane. 2. In the Properties pane, type the text that you want to appear in the document map in the DocumentMapLabel property, or enter an expression that evaluates to a label. For example, type Sales Chart. 3. Repeat step 1 for every report item that you want to appear in the document map. 4. Click Preview. The report runs and the document map displays the labels you created. Click any link to jump to the report page with that item. To add unique group values to a document map 1. In Design view, select the table, matrix, or list that contains the group that you want to display in the document map. The Grouping pane displays the row and column groups. 2. In the Row Groups pane, right-click the group, and then click Edit Group. The General page of the Tablix Group Properties dialog box opens. 3. Click Advanced. 4. In the Document map list box, type or select an expression that matches the group expression. 5. Click OK. 6. Repeat steps 1-4 for every group that you want to appear in the document map. 7. Click Preview. The report runs and the document map displays the group values. Click any link to jump to the report page with that item. Thanks, Challen Fu
