Parameters
| Name | Description | Type | Required | |
|---|---|---|---|---|
| Entity | The type of the instance that should be updated. | Module Element - Entity | Yes | |
| Select one or more | You can use an expression to select the instance that you want to update. They have to be instances of the entity selected in the above parameter. If left empty, it is assumed that the selected entity is either singleton or that an active instance exists. | Expression | No | |
| Clear existing values | Clears all attributes and relations before execution. | Boolean | No | |
| Attributes and Relations | Add one line for each attribute or relation that you want to set. | Line | No | |
| Attribute | Select an attribute or relation of the entity selected above. | Module element - Attribute/Relation | No | |
| Value | Write an expression that results in a value for the selected attribute or relation. Leaving the expression empty or removing it clears the value of the selected attribute or relation. | Expression | No | |
This service executes all lines from top to bottom, so you could use the new value of an attribute or relation that you set in a previous line by using this attribute or relation in the expression of a next line. You can use attributes and relation in your desired order.
The selected instance is not active in expressions. This allows for copying an instance of the same type. To have the option to have it active is an improvement for the future.
Example
Imagine a situation in which you want to update all job instances. You want to calculate the years of experience. All jobs that have no until date filled in, should get the value TODAY. The service shown below will update all job instances with an unknown end date within one service.
- All Jobs are selected that have an unknown end date with the expression:
COLLECT Job FROM ALL Job WHERE (Job.EndDate = ?) - The attribute
Job.EndDategets the valueTODAY- This is done for every instance found by the expression.
