As a Purchasing Manager, when working with a procurement system like SAP Ariba, you may need to verify if a specific configuration key, such as 'some_configuration_key', is set within the configuration of a particular purchasing process. Can you provide the specific process or example of the configuration for which you need to check this key?
### Response:
from igraph import Configuration

config = Configuration.instance()
key_to_check = 'some_configuration_key'

# Determine if the configuration contains the key
