Archived transaction in CRM

hi experts,

One of the transaction is avaliable in ECC , but the same contract is not avalaible in CRM.

here the business scenario is that Transaction are created in CRM and transfering the same to ECC.

I want to know how can we view those transaction or how we can able to know that has been archived in CRM.

Please throw some light for the same.

Thanks in advance
