Hi. I'm trying to add a checkbox column to the stages matrix. My first attempt was to use the subtype BoFldSubTypes, but I'm getting the error below when running it in SAP B1 Hana. Using SQL Server in my machine it worked perfectly.
Here is the error and the BoFldSubTypes definition.


I also tried to use a regular column with no subtype and change the matrix column type, but Type property is read only
myColumn.Type = BoFormItemTypes.it_CHECK_BOX; //ERROR. ReadOnly
Any solutions?
