Identify Complexity in PR

Hello time!

I need help!

The purchasing manager needs to classify the purchase requisitions according to their complexity (High / Medium / Low). This is necessary to indicate to the Buyer how much time he has to complete the quotation process, considering the complexity of the Requisition. Ex: Requisition with Low complexity, he must finalize the quote in 10 days.

Here is some information:

1) the client has 5 types of PR flows;

2) the requester does not have information about the complexity of the PRs;

2) the purchasing manager is the last approver of the requisition and it is he who knows how to make this complexity classification;
