Add custom ReportParam field to App Layer

Hello,

I added ReportParam.Cure_Date field to the ReportParam dataview and added the same field to the RDL RptParameters dataset. When running the report, I am getting the following error:

Query execution failed for dataset ‘RptParameter’. —> Microsoft.Data.SqlClient.SqlException: Invalid column name ‘Cure_Date’.

In classic Epicor I was able to bind the ReportParam.Date01 field and the RDL would already have the Date01 field present.
What am I missing?
