Create a dimension key

Before your link dimension can be used by others, you must create a dimension key for the shared dimension to link to.

Note: You can create multiple annotations on the same field. For example, you might want to create an attribute and a dimension key on the same field, such as Year, in your time dimension.

1. If you haven't done so already, complete steps 1-7 in Use the Annotate Stream step.

2. From the list in the Annotations table, choose a field to use as the dimension key by double-clicking it.

   For example, you may want to use the field Calendar Year as the dimension key for the shared dimension Year. Optionally, you can select the field in the Annotations table and then click the Edit (Pencil icon) in the upper-right corner.

   The Annotate dialog box appears for the selected field.

3. Select Create Dimension Key from the Actions drop-down menu for the field.

   The Name - Value table auto-populates with the name and value of the dimension key. You can edit the value to use as the dimension key.

4. Click OK to save the annotation and close the dialog box.

   In the Shared Dimension dialog box, the selected field will now appear with the summary that it is the key for the shared dimension. For example, the field Calendar Year may display Calendar Year is key for dimension Year in the Summary column.
