Calculated fields show #Error when placed on Report Builder report.

[MDKCLIRResearch]

I hope this is the right forum. This is the forum that comes up when I click the "Forum" button in Report Builder.

I am finding that the most basic calculated fields show #Error when placed on a report.

• I am using Microsoft Report Builder 15.0.20073.0 
• I am following the instructions at Add, Edit, Refresh Fields in the Report Data Pane (Report Builder) - SQL Server Reporting Services (.... 

A calculated field as simple as:

MyCalcField = "Hello"

shows #Error when placed on a report.

My questions are:

1. What am I doing wrong?
2. I assume that calculated fields can be placed on reports. Is this correct? Are there limitations or pre-requisites for placing calculated fields on reports?
3. Is it possible to substitute Crystal Reports for Report Builder in SSRS?

It's hard to say what you are doing wrong, there is not enough detail here. How are you placing the field onto your report - is it in a single text box or in a table?

If it's in a table it should work since calculated fields are calculated once per row. If you have just dragged on a text box it depends how you are aggregating the calculated field. In the example calculation you've given you are returning a string so you would need to use something like a First() or Last() aggregate, not one of the mathematical ones like Sum()

If I add a field like the one you've shown

It works fine if I use it in a table output
