1. Lookup Transformation (Dynamic lookup enabled)
Use NewLookUpRow Attribute to determine if it is a
new(1),updated(2) or no change(0) record.
2. Update Strategy
Use condition on NewLookkUpRow value to Insert or Update
the record in the target or Reject it.
IFF(NewlookUpRow = 1, DD_Insert, IFF(NewlookUpRow =
2,DD_Update, DD_Reject))

Answer / madhava
In this scenario generally using the two transformations
(Joiner&UpdateStrategy Tx) if S1 and S2 are different
sources or Flat files;
Else if both are in same sources as of relational then
join it in SourceQulaifier Tx itself in this case no need
for Joiner tx.
1) Joiner Tx will join the S1 and S2 by using common
fields; here S2 is the Master table.
2)In UpdateStrategy Tx. Condition is like IIF
(s2.empno=s1.empno,1,0)
