If I have set the property Treat Source Rows as Insert and
for the target properties I have checked the boxes Update as
Update, what will happen to incoming rows?
What exactly is the use of these check boxes and in which
scenarios we use them. Also what is the sequence in which
informatica understands these properties.Does it takes
whatever is defined in treat source rows as property or it
is in any other way. Please explain.

Ans-
All records will be reject if you not enable insert
option.Additionally what option you choose no matter.

By default the treat source row is always Insert option.If
you use a update strategy transformation in mapping it will
converted to Data Driven,it means what operation will
happen(insert,update &delete) will be finalized in update
strategy.Update strategy has 4
parameter(dd_insert,dd_update,dd_delete & dd_reject).As per
your parameter logic the record will tagged for target
operation.As example Insert tag for a record means it will
insert in the target table if target insert option is
enabled.Otherwise the records will be rejected.Likely for
delete and reject.But for update tag in target there are 3
options update as update,update as insert and update else
insert.if you choose any of last two it will insert the the
record in target if simultaneously insert option is enabled.
There is no order of operation only based open the options
you choose.
Think it clear all.
