The process to indicate intent to declare subcontractor commitments after bidding on a project is available in the DBE Window, which can be accessed by clicking on the DBE node in the Project Tree Structure.
The user must be authorized to bid on the project.
To indicate the intent to Not Subcontract:
Check the "I do not intend to declare DBE subcontractor commitments until..." box in the Subcontracts window.
This checkbox is inactive if there are any subcontractors in the table
