The costs that are expected to occur for each contractual maintenance activity belonging to a contract activity definition. Expected costs can be one of three types: additional costs, material costs and labor hour costs.

Expected costs are added to the selected maintenance activity definition at Contract activity details. Each type of maintenance cost is represented by its own icon in the elements list.

When maintenance orders are generated for a contract activity definition, any associated expected costs are copied to the estimates of the generated maintenance orders in Work Orders .

For the Contract maintenance activity definition costs, you can define, if the actual price (as defined on the product) should be used or the material costs of the purchase item should be used.

Select Yes on the Contract activity definitions - expected costs > Use actual price field.
The actual product price is applied, only when the Product requisition process is applied on the SLA scopes & activities > Contract activity definitions level.
However, if the Product requisition process is not applied, the Use actual prices is disabled and the price as defined on the material costs are used.
