 Previously, we classified our organization units into two groups, health centers and hospitals. In this video, you will see how to further organize your organization unit groups into group sets. We will create an organization unit group set called facility type and add both the hospital and health center groups to it. From the maintenance app, navigate to the organization unit page and then organization unit group set tab. As usual, to add a new item, click on the plus icon in the bottom right corner of the screen. Here, you will see that there are a couple of different fields available. Let's start with the two mandatory fields, the name and the short name. We will call this organization unit group set facility type and we can use the same short name. We can assign a code to this group set, just like when creating organization unit groups and organization units. We can also provide a description of the group set which describes it in a bit more detail. Providing a description is best practice to help users understand the structure that you have created. We then have some checkboxes below. The compulsory checkbox indicates that every organization unit in our hierarchy must be included in one of the groups that are within this group set in order for the group set to be used. In this example, let's leave compulsory deselected. The next checkbox is for data dimension. If we tick this box, it will allow us to select this group as a dimension in the analytics applications. This means that we can view our data based on whether or not they belong to a health center or a hospital. Note that if the organization unit group set is used as a data dimension, each organization unit should be only a member of one group within the group set. This ensures we avoid double counting if the dimension is used in analytics. Leave data dimension selected. There is also a checkbox marked include sub hierarchy in analytics. We will leave this deselected. You can find out more about this option in the djs2 documentation. Then let's add in the organization unit groups that belong to this particular group set. Double click on the organization unit groups, health center, and hospital in the available list to add them to the group set. To finish, click on save. You have now created your facility type group set, which includes hospital and health center organization unit groups. In summary, you have learned how to further organize organization unit groups into organization unit group sets and how that allows you to use the organization unit groups in djs2 data analysis apps. To create a new organization unit group set, open the maintenance app, select the organization unit tab, then select the organization unit group set button. Then click the blue plus sign to add a new item. Next, fill out the fields to identify the group set, such as name and short name. And lastly, add the organization unit groups into this set.
