In Smartsheet all team members are treated as full-timers but in Resource Management individual members working hours can be configured via profile account settings.
In Smartsheet we have added an 'estimated hours to complete a task' column that is converting into Allocation %. The Allocation % column is then pulled through to RM to calculate utilisation rates.
I have used the following example to explain my issue.
Emily works 21 hours per week – Wed, Thu, and Fri
In Smartsheet, the allocation % column does not consider Emily only works 3 days so the % is calculated based on a full-time worker (60%), not part time.
When the Allocation % information pulls through to Resource Management the estimated 21 hours (from Smartsheet) is calculated at 60% reducing Emily's working hours to 12.6 hours over the week. This is a variation of 8.4 hours.
The fact that Emily works only Wed, Thu and Fri is only accounted for by cutting down this overall time, even though part-time hours have been entered into Emily's profile in RM.
Looking forward to hearing from any SS users that are experiencing similar issues.
