Where will we use onChoiceCreate transform map script.

Give me one example

Hi Rahul,

One such example is - 

There a choice type field and you want that when a new choice is inserted then a record in a remote table is created. To accomplish the same you need to write a on choice create script.

Hi Rahul,

When: The onChoiceCreate event script is processed at the start of a choice value creation, before the new choice value is created.

Import Set JS objects available to be referenced and their context in the onChoiceCreate event

Import Set JS object	Type	Context in the onChoiceCreate import set event
source	GlideRecord	The row of the source table that is currently being processed.
target	GlideRecord	The row of the target table that is currently being processed.
map	GlideTransformMap	Read-only information about the current transform map record.
log	Function	The log object for the current import run. For example, log.info(...), log.warn(...), log.error(...).
action	String	Action returns a value of either "insert" or "update" indicating whether the current target row is about to be created or updated.
name	String	Evaluates to the field name of the target record for which a choice value is about to be created.
value	String	Evaluates to the display value from the source record for which a choice is about to be created.
ignore	Boolean	When set to true, ignores the creation of a choice value.
error	Boolean	When set to true, rejects the entire transformation row, no data is saved for this row.

Example:

//Create an event
var e = new GlideEvent("myimport_ChoiceCreate", action, value, "");
e.insert();

Hi,

ON CHOICE CREATE

This gets executed when a new choice is added on the transform. This transform script is triggered before the choice value is created in case there's any preparation, clean-up, preconditions, etc... for the new choice to properly exist.

Variables: source, target, map, log, action, name, value, ignore, error

Summary: onChoiceCreate runs before a new choice is created on a choice field. Since this script runs when a choice is created, “create” has to be selected as the choice action for that field map. If it is not selected, the script will not run. Because onChoiceCreate is a before action, only the source table record has set values. Similar to onForeignInsert, the onChoiceCreate script can take additional action when a new choice is created on a field.

Mark it as correct/helpful,if it helps.

Regards,

Ragini

Hi Only Data import time. Incident from is on the State field. If I want to add some value to this field then we can write OnChoiceCreate Transformer script.
