Need BI 4.0 WebIs from .NET Apps?

If you're investigating migration to BI 4.0, you probably already know that BI 4.0 doesn't include a plug-in to let you schedule Web Intelligence reports from .NET applications. If that's all that was keeping you from migrating, then we have good news: the APOS WebI .NET plug-in lets you schedule WebIs and manage defaults from .NET applications.
We created this plug-in to allow our own well managed BI solutions to work with BI 4.0, and now we're offering to the SAP BusinessObjects developer community. The APOS WebI .NET plug-in lets the developer handle format, prompt information, and other flags while scheduling Web Intelligence reports from .NET apps or saving report defaults.

Another issue that our plug-in solves is prompt reconstruction. When you create a new Web Intelligence report, or update an existing one, the prompt information on the report object becomes unavailable to the developer through the SDK. The APOS WebI .NET plug-in uses prompt reconstruction functionality to let the developer access the prompt information. You can schedule the report with the reconstructed prompts or save the report object for later use. You do not have to update the source report in order to schedule an instance.

You will notice that we are not using the GetPluginInterface method to initialize our plug-in. On a Web Intelligence object that method simply fails regardless of what you try to do with the returned object. We actually support using the plug-in interface to initialize our plug-in but this will not work with a Web Intelligence object. We tested it with other InfoObjects with no issues.

                        plg.WebiFormat = APOSWebiPlugIn.CeWebiFormat.ceWebiFormatExcel

                        Dim prompts As List(Of String) = plg.WebiGetPromptList()
                        'GEt the lsit of values for the first prompt
                        Dim vals As List(Of APOSWebiPlugIn.WebiPromptValue) = plg.WebiGetPromptValues(prompts(0))
                        'Clear the list of values
                        'Add Texas as the only value for the prompt
                        vals.Add(New APOSWebiPlugIn.WebiPromptValue("Texas"))
                        'Save the list of values back to the report
                        plg.WebiSetPromptValues(prompts(0), vals)
                        'Schedule the report
