PO type for repairing jobs

Hello,

I want to know what type of PO should we create for repairing Job.

Say suppose I have a Motor which needs to be repaired.

1. If i create a Service PO for repairing Job then there is no track of Material being sent for repairing JOB, also the cost is not capitalized.
2. Also if i am bearing the delivery charges that doesnt reflect in the material Doc as per note 381030.
3. And what type of PO should i create if i dont want to capitalize the cost but have to capture delivery charges.
