      Description

      The current definitions of the two hierarchy filter functions isancestor and isdescendant specify that the functions return true only if the current entity is a strict ancestor/descendant of the given start node.

      Practical applications sometimes require the start node to be included in the result. For this purpose, both functions could be extended by an optional Boolean parameter that allows the OData client to specify, if the start node shall be included in the result. With this, the filter expression $it/Aggregation.isdescendant(Hierarchy='SalesOrgHierarchy',Node='EMEA',IncludeParent=”true”) could avoid the clumsier $it/Aggregation.isdescendant(Hierarchy='SalesOrgHierarchy',Node='EMEA') or ID eq 'EMEA'
