Data Flow for New Rows

Data Flow for New Rows

The following table describes the data flow for new rows. For each new row in the source, this data flow creates a primary key and version number, and then inserts it into the target:

Transformation Name	Transformation Type	Description
FIL_InsertNewRecord	Filter	Uses the following filter condition to filter out any rows from EXP_DetectChanges that are not marked new (TRUE): NewFlag . Passes new rows to UPD_ForceInserts.
UPD_ForceInserts	Update Strategy	Uses DD_INSERT to insert rows to the target.
SEQ_GenerateKeys	Sequence Generator	Generates a value for each new row written to the target, incrementing values by 1. Passes values to EXP_KeyProcessing_InsertNew.
EXP_KeyProcessing_InsertNew	Expression	Uses the following expression to increment generated values by 1,000: NEXTVAL * 1,000 . Then passes incremented values to the target to populate the PM_PRIMARYKEY column. Creates a version number of 0 for each row to populate the PM_VERSION_NUMBER column in the target.
T_ TargetName	Target Definition	Instance of the target definition for new rows to be inserted into the target.
