SAP Message RH242 - &1 of &2 nodes in total not included in the hierarchy

Diagnosis
The root nodes are the starting point for moving through the hierarchy.The content of the fields NEXTID and CHILDID is used to move from thecurrent node to its sibling and child nodes.
V1 out of a total of v2 nodes cannot be reached by moving throughthe hierarchy in this way. These &V1& nodes are not connected to thehierarchy.

System Response
The hierarchy is not consistent and therefore cannot be activated.

Procedure
The cause of the problem is usually incorrect links to sibling nodes(field NEXTID) or child nodes (field CHILDID). An incorrect value oftenmeans that an entire subtree (consisting of several nodes) is notincluded in the hierarchy.
To simplify the search for incorrect links, the system identifies thenodes (from all the not connected nodes) that are not used as siblingnodes or as child nodes. These nodes are usually root nodes of subtreesthat are not connected to the hierarchy. You can find these nodes in theRH 207 messages that follow.
Try to localize the problem by using the RH207 messages for help. If thehierarchy is loaded from an SAP source system, you can check whether theextracted data is correct by executing transaction RSA3 in the sourcesystem. If necessary, check if the data is modified with a user exit. Ifthe hierarchy is loaded from a file, check the contents of this file.The problem might also be due to an error in the transfer rules or inthe transformation.
