Problem Note 20741: The target table is generated with incorrect data when multiple lookup
tables and the target table contain a column with the same name
If the following scenario occurs when you use a Lookup transformation,
SAS® Data Integration Studio generates the target table with incorrect
data values:
Scenario
The Lookup transformation contains multiple lookup definitions and two
or more of these definitions have the same lookup column being mapped to
different target table columns:
Lookup Properties
Lookups
First lookup definition
Source to Lookup Mapping
Source Table Lookup Table
---------------------------
AccountID -> Account_ID
Lookup to Target Mapping
Lookup Table Target Table
---------------------------
AccountRK -> Account_RK
Second lookup definition
Source to Lookup Mapping
Source Table Lookup Table
--------------------------------
TargetAcctID -> Account_ID
Lookup to Target Mapping
Lookup Table Target Table
--------------------------------
AccountRK -> Target_Account_RK
When this scenario occurs, the target column in the first lookup
definition gets set to the same value as the target column in the second
lookup definition.
You can avoid this issue by using unique names for the lookup table
columns and the source table columns. To accomplish this, insert a step
prior to the Lookup and map conflicting columns to new names.
