* **Select Child Module:** You can choose the module associated with the module where you create this field. Please note that only the multi-lookup fields can be selected.
* **Configure Aggregation:** Choose a field to run calculations and configure the operation that will be performed.
* **Select Field to Aggregate:** This is the field on which calculations will be based, and you can choose it from the available fields in the child module, filtered by the selected **Calculated Field Type**.
* **Select Operation:** Select the operation to be performed on the values of the chosen field.
* For **Number Type**, the available operations are:

* **Add Filter on Child Module:** If you apply a filter to the child module, calculations will only apply to records matching the condition.
* **Add Filter on Parent Module**: Similarly, you can filter the parent module, ensuring that only specific parent records are updated.
* Once done, click **Save** to add the calculated field.
