Parameters

Name Type Description

record

Name	Type	Description
record	sys.data.Record	This is the record associated to the operation. If field is inside an entity field, this will be the record that contains the field. If the field is an action parameter, this will be the record where the action is being executed.
parentField	sys.data.Record	This variable is only available when this is a field inside a nested field and it is based on the variable `record` or `action` (the same rules apply then it is an action parameter or an entity field). It is a `sys.data.Record` object with the difference that the root of the record is set to the nested fields containing it. This way it is possible to access fields in the nested group like `parentField.field('fieldA')` instead of `record.field('nested.fieldA')` or `action.field('nested.fieldA')`, which is specially needed when nested fields are multi-valued as you don’t know the index.
action	sys.data.Action	This variable will be available only if the field is an action parameter. It will provide access to other parameters.

sys.data.Record

This is the record associated to the operation. If field is inside an entity field, this will be the record that contains the field.

If the field is an action parameter, this will be the record where the action is being executed.

parentField

sys.data.Record

This variable is only available when this is a field inside a nested field and it is based on the variable record or action (the same rules apply then it is an action parameter or an entity field).

It is a sys.data.Record object with the difference that the root of the record is set to the nested fields containing it. This way it is possible to access fields in the nested group like parentField.field('fieldA') instead of record.field('nested.fieldA') or action.field('nested.fieldA'), which is specially needed when nested fields are multi-valued as you don’t know the index.

action sys.data.Action This variable will be available only if the field is an action parameter. It will provide access to other parameters.

Returns

boolean - You should return true if the field must be required, false otherwise.

Samples

 //if 'numberOfExmployees' is bigger than 10, then this field is required
return record.field('numberOfEmployees').val() > 10;
