The VTEX Sales App app allows the use of an Observation field, where it's possible to store additional information regarding the order.

The data entered in this field is sent via API to the Order Management System. They populate the openTextField field, which can be retrieved later either in the Admin or through an Orders API call.

A common example of using the Observation field is the case where the store wants to receive an identification number from the sales associate who made the sale, such as the sales associate code. In this case, the sales associate has to enter this number in the Observation field whenever closing an order.

To activate the Observation field on the order screen, open a support ticket to VTEX requesting this feature.
