Installation &1 is not a primary installation on &2

What causes this issue?

The <DS:DE.INSTGRTYPE>grouping type</> of installation &v1& has to be
determined for the key date &v2&. This is not possible due to one of
thefollowing reasons:
Installation &v1& does not exist on &v2&
Installation &v1& is not a primary installation on &v2&

System Response

primary installation in the periods that contain a grouping type.
