The MultiLoad INMOD Adapter operator allows you to use Teradata MultiLoad utility INMOD routines with Teradata PT. This operator can be used as a producer or a filter operator.

The term INMOD is an acronym for “input modification.” INMOD routines are user exit routines the MultiLoad INMOD adapter can call to provide enhanced processing functions on input records before they are sent to the Teradata Database. Y

You can use the MultiLoad INMOD Routine with the MultiLoad INMOD Adapter to read and preprocess input data values from files on the client system. These then provide the USING data for a subsequent SELECT statement.

For information on creating and using FastLoad INMOD Routines, see the Teradata MultiLoad Reference (B035-2409).

The following two figures show the MultiLoad INMOD Adapter operator as a producer operator or as a filter operator.

MultiLoad INMOD Adapter Operator as Producer Operator

MultiLoad INMOD Adapter Operator as Filter Operator

To use the MultiLoad INMOD Adapter Operator as a filter operator, define the operator as TYPE MULTILOAD INMOD FILTER in the DEFINE OPERATOR statement and then use the VIA clause to invoke the operator in the APPLY statement. For VIA clause usage, see Object Definitions and the APPLY Statement.
The existing TPT function names should not be used in User's INMODs. Using the existing TPT function names in User's INMODs might cause the normal operation of the TPT job to behave with unexpected results and prevent requests from completing normally.
