Visualisation - Link Dimensions between two models


Hello everyone,

today I tried to further study the modeling functionality of SAP C4A.

Meanwhile I generated some detailed models with relevant financial data from an SAP ERP system.

Now I wanted to combine some of these models over the "Link Dimensions" functionality and ran into a problem through the visualisation within a story.

I started small and created the following two data models with simple values. The ID's and the description are identical, but the values (key figures/signed data) are different to see the impact.

Model 1:

ID Description Value 1 Text 1 10 2 Text 2 20 3 Text 3 30 4 Text 4 40 ... ... ...

Model 2:

ID Description Value 1 Text 1 1000 2 Text 2 2000 3 Text 3 3000 4 Text 4 4000 ... ... ...

I imported this model and the data successfully into C4A and created afterwards a new story.

Within this story I added both of them and linked the ID dimensions over the "Link dimensions" Button.

As you can see in the image above I was able to set the ID dimension successfully.

After this step I tried to create a new chart with the values (signed data) from both of these models through the generated link like it is described in the userguide.

In the following image you can see that the system tells me the following errormessage:

"Unable to retrieve data from the server. Error: [Cannot read property 'type' of null]

I understand this function like a Join between two "tables" where I need a key which has to match in both models (which it does in this data setup).

In this case I do not know why the system is not able to create a chart. I tried every available chart-type and none of them worked in this simple scenario.

Have I misunderstood something or did I do something wrong?

Thanks a lot in advance!

Best regards,
