A maintenance order with status REL means that the order is released and ready for execution. At this stage, the following characteristics apply:

A. Goods receipts for external services can be entered. This is true because external services are procured through purchase orders that are linked to the maintenance order. The service performer can post service entry sheets to record the executed work and consumable materials. These service entry sheets can be approved and posted as goods receipts for external services1.

B. The planner can change planned costs at the operation level. This is false because once the order is released, the planned costs are frozen and cannot be changed by the planner. The planner can only change the estimated costs at the header level2.

C. The planner can change estimated costs only at the header level. This is true, but it is not a characteristic of a released order. The planner can change the estimated costs at any time, even before the order is released2.

D. The controller can determine actual cost surcharges. This is true because the controller can use the business function LOG_EAM_CI_7 to calculate and post actual cost surcharges for maintenance orders. This function can be used for orders with status REL or TECO3.

E. The assignment of the notification to the maintenance order header cannot be deleted. This is true because the notification is the source document for the maintenance order and provides the reason for the order. The notification can only be deleted if the order is deleted or set to status CRTD. References: 1: Lean and Limit Value Services in Maintenance Order 2: Maintenance Order Cost Analysis 3: Actual Cost Surcharges for Maintenance Orders : Notification Assignment to Maintenance Order
