Couldn't load the data for this visual Error

[AdamTass1]

I am linking 2 DBs via the Relationship function. When trying to add fields from 1 of the DBs to a report, the report errors out & returns a 'Cant display the visual' message. There are no calculated columns in either datasets that would cause a major spike in memory usage when modeling. I have 8 GB of RAM - I'm unsure how to move forward, anyone have any suggestions?

I ended up creating a measure in the Bank DB for the mortgage loan total amount. That seemed to solution my problem of erroring out due to lack of memory. Adding fields from either table is snappier.

When you hit the details button, is it specifically telling you this is a memory problem? It may simply be that you're putting columns together in a way that your model can't aggregate because of the relationships you have or haven't created. What is the exact error message it's giving you?

I am then prompted to Close ot Send a frown.

OK, so you have a relationship between these two tables? Do you have the filtering direction set to "Both" on that relationship, or "Single"? What are you trying to display in this visual exactly? Are you using a measure, a quick measure, or what?

[AdamTass1]

Single.

I have 1 DB of SSNs of bank clients that I am trying to agrregate against a DB of Mortgage clients's SSNs to see how many Mortgage clients are also Bank clients.

I am not using any measured columns.

[KHorseman]

That doesn't really clarify what visual you're using and what data is going where in it.

[AdamTass1]

my appologies - I am using a table visualization.

I am starting w the full list of banks client SSNs from DB1. The next column is from DB2 that has all the mortgage client's last names. Once those 2 columns are in place I filter out any blanks from the mortgage client's last name column as that returns a list of mortgage clients who are bank clients as well bc DB1 is linked to DB2 via SSN.

Adding any other fields from DB2 results in the error, mortgage loan number, mortgage loan amount, application date... etc.

[KHorseman]

So DB1 is just a table of client SSNs? 1 row per SSN? i.e. each SSN appears only once? And DB2 is a table of mortgages where each row has a reference to SSNs found in DB1, with a relationship between these two columns?

[AdamTass1]

Yes - I removed the duplicates from each DB based on the SSN.

[KHorseman]

Add a measure

Total Amount = SUM(Encompass[Loand Amount])

and add that to the visual before adding any other columns. See if that makes any difference. Also try changing your visual to a matrix and put that measure under Values and see what that does.

[AdamTass1]

When using the Table visualization - each column replicates what is input in the 1st row next to the Bank Member SSN field.

The filter function doesnt work correctly in the Matrix visual.

@AdamTass1,

Could you please share sample data of your tables so that we can reproduce the scenario? And what output would you like to display?

Regards,
Lydia

My appologies - I dont have data sets I am able to share.

That's what I suspected. When you just jam a bunch of columns together it isn't sure what to do with them. You need something to tell it how you want to aggreagate things and then it works smoothly. Honestly you're not really using Power BI until you start writing a few measures in my opinion.

[AdamTass1]

Thanks again for all your assistance.
