How invoicing works when a service contract is created from OM

Hi All,

How invoicing works when a service contracts are created from OM. I could see an invoice number against each service line with amount entered on the order managament. Does it mean the invoicing of the contract is completed or do we need to check anything from service contracts.

I am asking this question as our users entered service duration incorrectly from order management. Hence, contracts have been created with wrong duration.

Now our action plan is to create contracts with correct duration through scripts with zero dollar amount and to just terminate the contracts which are created incorrectly by supressing the credit. Please let me know your thoughts.
