Should cdisc parent datasets have parents?

[cicdguy]

Do we need to limit the cdisc to only let datasets either have or be parents not both - or we need to change the getparent function to have an optional arg for getting all parents up the DAG otherwise cases like x has parent y has parent z and we filter on z in the filter panel and then use say only x in the cross table, the show r code will not give the same answer as it won't include the z filter

If the filter panel does not work properly with long ancestry:

1. fix the filter panel
   or
2. limit the ancestry

Can we fix the filter panel easily?

Let's not allow parents to have parents as we don't have user use cases which require this
