Structure Relationships
Definition
Structure relationships are mappings between structured trees.
A mapping between two structured trees is allowed if the following applies to all nodes Ti and Tj with Ti~Tj: S(Ti) ~ S(Tj).
Use
The mappings between the trees have to make sense. This means, the structures of the data to be migrated (referred to as "source structures" in the following) have to be created within the hierarchy in a way that they can be allocated to the structures in the SAP system (referred to as "target structures" in the following).
Structure
The LSMW uses the following basic model:
Target tree T and Source tree S are given. Assume that the node of S associated with node Ti of T is named S(Ti). Two nodes are in relation to each other ( Ti ~ Tj) if there is a path from Ti to Tj. Obviously, this does not define any equivalency. The root node is in relation to all nodes.
