Enumerate Universe fields that are used by WebI report?

sdk development
1

I’m hoping to determine the effects of changing or deleting a field in a Universe will have on the associated WebI reports.

Using the BusinessObjects .Net SDK, I can easily determine the linkage between Universes adn WebI reports.

What I need is the mechanism that will analyze a given WebI report. It appears that the WebI Java SDK, has the desired functionality, but it doesn’t have a .Net version.

As I have other meta-data functionality built in a .Net application, I’m guessing that I will need to write an Xml Webservice in Java that will expose the functionality that I need to my .Net application.

Has anyone tried to accomplish:

  1. use the WebI SDK to enumerate fields
  2. wrap the Java SDK with an Xml Webservice

Thoughts appreciated.

The SDK you need is Report Engine SDK. It has both Java and .NET versions.

Do you mean the Report Application Server (RAS) SDK? I thought that was just for Crystal Report-type reports.

No. I mean Report Engine. For Java it is referred to as REBEAN and for .NET it is referred to as RENET.
It is used for Webi and Deski reports.

Thanks. I had no idea this was available.

Off the top of your head, do you know which classes represent the ‘fields’?

I am not familiar with .NET.
I know in Java you can use ReportExpression or VariableExpression class to get list of varibales used.
Code snippet like this:

DocumentInstance doc=repEng.openDocument(idocID);
for (int i=0; i < doc.getDictionary().getChildCount(); i++){
	exp = doc.getDictionary().getChildAt(i);
	dobj = exp.getDataSourceObject();
	ds = exp.getDataSource();
}

ds would be your universe and dobj would be the object in that universe.

Hope this helps,
