This activity is used to add an approval to the sub contract. In several stages of the sub contract it needs an approval process to proceed. For example, when releasing a sub contract, the Contract Manager may be required to approve the scope of the contract created. Or when awarding the sub contract, again it may need approval. Since the same approval routing can be used in several stages of the sub contract, the required approvals can be defined initially when creating the sub contract, and will be triggered in the event of a status change on the sub contract.
