 Let's add these groups to an organization unit group set. In this case, the group set name is facility type. This is how we have defined it earlier in our documentation. In order to do this, we will click on organization unit group set, and then we'll click on the plus icon. In the organization unit group set screen, we can see that there are a couple different fields available as well. We start with the name, the code, and the description. The name is self-explanatory. In this case, we are working with the facility type group set. We can also assign this a code, just like we can in organization unit groups and organization units. We can also provide a description of the group set, which describes this in a bit more detail. We then have two checkboxes. This includes compulsory and data dimension. The compulsory checkbox indicates that every organization unit in our hierarchy needs to be a part of the groups that are within this group set. So for example, if I created the health center group, and I did not include one of my organization units, I would not be able to work with this health center group in this particular group set. That is of course only if I have this compulsory box selected. The next box is for data dimension. If we tick this box, this will allow us to select this organization unit group set during analysis. This means in this particular case, I can separate my data based on whether or not they belong to a health center or a hospital. This is usually quite useful, and by default it is already selected. We'll start by giving the organization unit group set a name. We are working with the facility type example, so we will give it the name facility type. We will leave data dimension selected and compulsory deselected. We then have to add in the organization unit groups that belong to this particular group set. In this case, we can just assign both of the group sets. But in the event that you have other organization unit groups available, you can always double click on the organization unit groups that you want to select. After I've selected the organization unit groups that I want to be part of this organization unit group set, I can go ahead and click on save. Now I have created the organization unit group set for facility type. This contains the organization unit groups of hospital and health center. The health center and hospital organization unit groups contain our individual organization units which we created in the first step in this demonstration.
