Sometimes when you are creating a contract an error will appear with the following text:
Contracts can be generated for the purposes of your organization. Each contract covers a set timeframe encompassed by Start Date and End Date. During the duration of the contract, steps can be set, each with a different time period. The Steps are defined with a start date and an end date that can be found next to the Steps field.
The First Step of a contract must begin with the start date of the contract. Each next step has to start on the following day that a step ends. The last step has to end on the last day of the contract. Thus the steps will be covering the full duration of the contract.
