SSRS exception

Posted on by Samy123 455

There is row group in a Tablix that has hidden property for visibility set as

IIF(field!ABC.value = "", True, False)

Sometime not always SSRS throw exception  

Microsoft.ReportingServices.Diagnostics.Utilities.RSException: The Hidden expression for the tablix ‘Tablix1’ contains an error: The expression references the field 'ABC', which does not exist in the Fields collection

Any ideas what might be wrong?

    Is this happening only for specific users?

    I'm wondering if it could be related to the security settings for the table being queried.  If a user does not have access to some of the fields, then they tend to get removed from the data set returned by the query/rdp class.  Maybe that could account for why ABC field sometimes is not there?

    I'm not ssrs expression expert, but according to the topic here msdn.microsoft.com/.../dd283100.aspx

    you could try checking if the ABC field exists using the expression

    Code.IsFieldMissing(Fields!FieldName).

    Maybe try setting hidden to true if the expression above is true, else set it using the expression you currently have?

    Hope this helps

    Thanks Lance for your suggestion. I already did some tweaking to the expression I am using isNothing() function to check the value. If it doesn't resolve the issue then I will go with the Code.IsFieldMissing(Fields!FieldName). Waiting for the results.
