Buying a single use material for Maintenance job

Hi all,

We've recently implemented SAP so i'm quite new to the system.

We're a port operator and most activity in the system is via maintenance and engineering. We have a requirement to purchase parts for equipment maintenance. The parts will be used with such infrequency as to be effectively single use - we'll buy it, consume it immediately as part of a maintenance work order and then likely never order it again.

What is the best practice in respect of such a requirement? Ideally, I don't want to create a new material master for each such occasion.

Any help is greatly appreciated!

Kind Regards,

Mark
