Calling an unconnected lookup from another transformation

Supply input values for an unconnected Lookup transformation from a :LKP expression in another transformation such as an Expression transformation or Aggregator transformation. You can call the same lookup multiple times in one mapping. You cannot call an unconnected lookup from a Joiner or Java transformation.

Use the following syntax for a :LKP expression:

:LKP.<Lookup transformation name> (<argument>, <argument>, ...)

The arguments are local input fields that match the Lookup transformation input fields used in the lookup condition.

For example, the following expression passes the ITEM_ID and PRICE fields to an unconnected Lookup transformation named lkp_ItemPrices:

:LKP.lkp_ItemPrices (ITEM_ID, PRICE)

Use the following guidelines to write an expression that calls an unconnected Lookup transformation:

The order in which you list each argument must match the order of the lookup conditions in the Lookup transformation.

The datatypes for the fields in the expression must match the datatypes for the input fields in the Lookup transformation.

The argument fields in the expression must be in the same order as the input fields in the lookup condition.

If you call a connected Lookup transformation in a :LKP expression,
