Hello
Please check in below configuration path
Plant Maintenance--> Maintenance and Service Processing-->Maintenance and Service Orders--> Functions and Settings for Order Types--> Define Settlement Rule, Time and Distribution Rule.
As per STD SAP Settlement rule is created When the order is released Or Only when the order is completed.
So Check what is the setting in Plant Maintenance--> Maintenance and Service Processing-->Maintenance and Service Orders--> Functions and Settings for Order Types--> Define Settlement Rule, Time and Distribution Rule.
