Adding Custom OM infotype in Adhoc Query

Hi All,

I have created a custom OM  infotype . This infotype contains  only the description of job, i.e job notes . Below  is questions on this:

1) When I am trying to add this infotype in infoset,then I am able to see this infotype in "related to object type" folder under TWO different relationship .Why its coming under relationship part. There is no relationship for this infotype .'

To include this in infoset do I have to select this infotype under both the relationship.?

Please find the screenshot of the relationships under which this infotype is coming:

Thanks,
