Operations for reporting per-employee values for a deviation period from an external system. An external period carries a percentage-based project/cost-center distribution for the employee's worked time. The values are picked up when they are imported into the payslip for that period. A period cannot be updated — delete it and create a new one instead. An integration can only see and manage the periods it has created itself. Overview of the project and cost center distribution of ordinary working time on the payslip: [Fördelning ordinarie arbetstid](https://support.spiris.se/lon/sv-se/content/online-help/payrun-adjust-payslip.htm#fordelning-ordinarie-arbetstid)
