Hi Piet,

We do not have functionality to revert the cancellation of a customer contract.  There are several things that may occur with the cancellation process:

• Contract End date is set to date of cancellation
• Contact Line end dates is set to date of cancellation
• Pricing is adjusted for contract lines (or contract if a fixed price)
• Billing Schedules are removed / price of last valid date is adjusted
• PM Schedule are removed
• Revenue Recognition is update and future revrec is removed.

You may be better served by creating a new contract instead. Reversing contract cancellation can be fairly complicated.
