One of the main benefit of using Power BI as a Self-Service BI tool is the capability of to build data models. What that means is instead of forcing every source of data into a single table, which will inevitably require over-simplifications, data loss or even errors, in Power BI it is possible to import multiple datasets and define relationships between them as easily as. Here we have 5 different queries, connected to 5 different data sources, that are pulled into a single model. They are then linked by relationships which will have an effect on visualizations and filters. When starting to use this technique, one of the first and most frustrating issue that may be encountered is the following: Dragging the key column from one table to the other results in a message saying: “ You can’t create a relationship between these two columns because one of the columns must have unique values.” The cause is simple: Power BI can only create relationships between 2 tables if at least one of the two selected columns hosts a distinct, unique list of the key values. It is to be noted that this is not a limitation specific to Power BI, it is in fact one of the basic design principle of all technologies (the concept of primary and foreign keys). We will see more about that later, but it makes sense that in order to be able to find something, it needs to have a unique address. Durruti column lc download for mac.

Many Errors When Duplicating LatheMail Merge Label printing: Problem with data duplicating Hi, I have successfully merged my Excel spread sheet and formatted the labelling so it prints correctly. Many Errors When Duplicating Products![]() We can work around that in 2 ways: • Edit one the query and make the column a distinct list of the key values by using ' Remove Duplicate Rows' on it. The issue with this approach is that we will lose information, as usually the key is duplicated for a good reason (see example below) • Add an intermediary table made of the list of distinct key values to the model, which will then be linked to both original columns Let’s illustrate that through an example. Our data is going to be coming from 2 Excel tables, one containing the employee expenses by month, the other their monthly budget allowance by category: We can quickly load those datasets into Power BI Desktop via 2 queries, but when we try to build a chart comparing monthly expenses versus budget, pulling from the 2 resulting tables, the numbers just don’t make any sense: To solve that we know that we need a relationship between those 2 tables, using their common attribute: the employee column. But of course, at that point we will get an error message when we try to create that relationship: Now we know why: in both tables the employees are duplicated, repeated either by months or by categories. Neither column contains a distinct list of employees, we need to build it ourselves. We have to take this approach here, as doing otherwise would result in an impacting loss of information (no more categories, or periods). To do that, we first need to create a new query, appending values from both existing ones: in the query editor, Home tab, select Append Query as New.
