Incomplete composite templates
Composite templates are a collection of feature templates. These feature templates can come from multiple layers. If a composite template is created from multiple layers and one of those layers is not present or visible in the table of contents, the composite template is displayed as an incomplete composite template. Incomplete composite templates appear with a symbol to indicate they cannot be used to create features.
Composite templates must have all the layers available before you can create features with them. To fix an incomplete composite template, use the Composite Template Properties dialog box to identify the layers that are missing from the composite template, then choose the best method for fixing the template.
There may be situations in which you cannot fix the incomplete composite template. In these situations, you can disable the incomplete composite templates so they are not displayed on the Create tab on the Manage Features window.
