SAP Analyitcs Cloud - Linking models does not support totals in tables

Dear community,

would be great to get some help. In SAP Analytics Cloud I have to link 3 models where the fields "product" and "customer" are the blending fields. I would then like to show data from all 3 models in a table.

While preparing the table I saw that the table is not supporting totals. I don't understand the reason for that. Or am I doing something wrong here?

Thanks for your help!
