Subscription Contract Revenue data not sent to RMCS

Summary:

Subscription Contract not sent to RMCS.

I have created a contract in Subscription Management with deferred revenue terms. (Deferred over the period of contract)

While running the "validate contract data" process, I'm getting below error:

You must define the contract accounts for this ledger in the Manage System Options for Revenue Management page Even though I have already updated the System Options with correct accounts.
