Differences between LIS & LOS extraction
A. LIS works on transparent table concept and LO’s works on
Cluster table concept.
B. Each data source i.e 2lis_11_s264 is splitted in to
multiple data sources like 2lis_11_vahdr, 2lis_11_vaitm,
2lis_11_vascl, with this we can give more detailed level of
information to the end users.
C. LIS works under Push mechanism where as Lo works on PULL
Mechanism.
D. when we r doing delta then two transparent tables will
come into picture i.e SBIW1 and SBIW2 in LIS. Where as in
Los structures called LBWQ (Extractor queue), SM13 (Update
queue)
and RSA3 (delta queue).

A hierarchy is a method of displaying a characteristic 
structured and grouped according to individual evaluation 
criteria.

A hierarchy is created from nodes. The relationships 
between the nodes are defined as follows:

*   The uppermost node is the root. There can be more than 
one root. They do not have a superior node.
*   Exactly one other node is directly superior to each 
node (except for the uppermost node).

Hierarchy Levels

All nodes on the same level of the hierarchy (nodes that 
are the same distance away from the root) form a hierarchy 
level. The roots of a hierarchy form level 1. The level of 
a node denotes the distance from the node to the root.

Leaves

The leaves of a hierarchy consist of characteristic values 
for the basic characteristic and therefore can also have 
entries in the fact table. In contrast to nodes that can be 
posted, a leaf cannot have any subnodes.

The CKF defined at the infoprovider level will be available
to all the query define for that perticular Infoprovider

RSO2

These are used for small values of data with few user;no 
master data allowed. performance is poor.
