Answer / suresh
we can load data without primary key but if whenever u need to update the table from informatica then u have to use update override then only u can update the table.
target plan: if u have maultiple source and multiple targets in one mapping then u have to go target load order this option available in mapping tab
correct me if i wrong

Answer / sbvp
acutally we need pk for updating records while using update
strategy t/r. if we want load the data into the target with
out pk is possible. while we don't create pk,fk in tgrt
table we will use bulk loading but there is no recovery
option for bulk loading. if u want recovery option for ur
mapping u can use normal trgt load type ok.

Answer / koti
by using update overide option we can update the target
though we dont have any primary key in target.
target overload means some time in a single mapping no. of
targets can take place one source can be depend on other
target. then we have to decide which target has to execute
first....
ex: source1.... target1(date of birth is one column in
target 1)
source2(age is one column is source2).... target2
in the above example target1 should be execute first. then
only we can get age in source 2. because age is depends on
date of birth which is available is target1...
hope u understood. if any clarification mail to me:

Answer / manjunath
Yes, we can load the data without the primary key, but if you want to use furhtet i.e to update we cant do it, for that we need primary key.
Target Load Plan : It is used if we have multiple sources and targets we go for this option (We can have this option in Mapping Tab)
