Peer sibling WO on which WO defined by cWOID depends; NULL means no dependency.

This field tells on which level of Work Plan WO defined by cWOID is placed. Only values 0, 1 and 2 are allowed: 0 means cWOID is the root (in this case RootWOID == cWOID); 1 means it’s a child; 2 means it’s a grandchild.

Numeric suffix used to build WO number for WO defined by cWOID. If cWOID is root this field is zero. Allowed values are 0 – 100, which means single parent cannot have more than 100 children.
