Question

Business View Error in Dynamic DataConnection

Asked by: diazluna

I am having a problem displaying my report in ASP.Net.  The report is under the BOE repository and is using a parametero for the Dynamic Data Connection to be able to connecto to different environments.

I know how to pass the parameters but I'm not sure why I'm getting the following error:

"Business View error in Dynamic DataConnection. Cannot open database.  Business View error in Dynamic DataConnection.

Here is the code I'm using to pass the parameters:

        reportClientDocument.DataDefController.ParameterFieldController.SetCurrentValue("", "Dynamic Parameter", "My_Dev_Env");
        reportClientDocument.DataDefController.ParameterFieldController.SetCurrentValue("", "req_id", Int32.Parse("161981974"));
        reportClientDocument.DataDefController.ParameterFieldController.SetCurrentValue("", "os_queue_pk", Int32.Parse("161982055"));

I don't use that product but generally the report is opened before it gets the parameters.  

Does BOE allow you to pass the data source that way?

The report is actually opened after the parameters are set.

Not based on the code but when the report actually opens, it needs to know where the data is and can't apply a parameter at that point.

Since I don't use BOE, I may be off base with that.

You actually are. :)

I found the answer.  When you are passing the value for the Dynamic Data Connection parameter you need to pass the VALUE and not the actual name of the Data Connection you want to use.

You can get the VALUE (which looks like a GUID) by openning the Report in Crystal Reports and editing the Parameter.  You'll see that the description is the name of the data connection but the value is a cryptic value.

Once I replaced the parameter with the actual value it all worked fine.

I hope this helps someone.
