PowerBI and IRIS generating "The column '...' of the table wasn't found." |

Question

#Analytics #InterSystems IRIS BI (DeepSee)

Hi,

I have 3 simple tables: Encounter, Patient and Immunizations. Encounter makes a reference to Patient, and Patient contains a list of Immunization objects.

I've tried using PowerBI to access IRIS (using ODBC connector, not InterSystems BI connector), PowerBI reports the error:

Expression.Error: The column 'Patient' of the table wasn't found.
Details:
    Patient

it does this for two of the three tables I need only (Patient and Encounter), but not for Immunization IRIS table..

Anyone know why and how to fix ?

Thanks - Steve

Product version: IRIS 2021.2

ok... Update: This definitely looks like a Microsoft bug.

Setting up the same classes/data in a new namespace on the same IRIS instance, and created a fresh DSN in ODBC to use works fine.

I even create a new namespace and global/package mapped all data from the original failed namespace, and created a fresh DSN in ODBC to use works fine too.

So - it's not the class/package/data definition in IRIS, or the IRIS version. There is something Power BI is holding onto, which is related to the original DSN Name used, that is causing grief.

I'm sorted for now.
