Introduction
Use the extendmissing instruction to check if certain columns exist in the data extract, and add them if they are missing from the data extract.
Creating a custom script enrichment using the extendmissing instruction
To create and configure a custom script using the extendmissing instruction, follow these steps:
-
In the Instructions step, select the extendmissing instruction.
-
To configure the custom script instruction, fill in the following fields. Required fields are marked with an asterisk (*).
-
Fieldnames
-
Enter the names of the columns to find in the data extract.
-
Missing
-
Enter the values with which to populate the new columns.
-
Subtable
-
Enter the name for a subtable that you want to use within this custom script.
A subtable is a temporary table that only exists for this custom script. You can apply additional instructions within the same custom script to the subtable. However, the subtable cannot be used in any other custom scripts.
If a subtable does not exist for the current custom script, the enrichment is applied to the data extract, and the enriched data is output into the subtable. If the subtable already exists for the custom script, the subtable is used as the input for the enrichment and optionally as the output.
