This activity is used to review a sub contract. Once the sub contract is awarded, it is common practice to review the contract. Note: Reviewing a sub contract is optional, and for companies that do not have this stage as a part of their business process, it is possible to skip it and go directly to the contract activation stage. When you are reviewing a contract, you may need to change the sub contract lines and items according to the tender or you can choose to create a new contract revision to include the necessary changes. The latter option, i.e., creating a new revision for the changes, is recommended, even though changes can be logged in the system using the Audit Trail feature available for contract revisions.
