Timesheet allows you to group by worklogs for using multiple criteria. You can do this when creating a custom report for the first time with the group field, or group field in the dialog that opens by clicking the adjust button in the report view. Multiple grouping is performed by selecting desired fields from the dropdown list opening from group field. There are three categories on the list. These are "Predefine", "Attributes" and "Fields". "Predefine" consists of some basic fields. Attributes part shows all attributes that are defined on the attributes page located in the Apps settings of WorklogPro. In this way, grouping can be done according to the created attributes. The "Fields" part consists of all fields except the fields in the "Predefine" part. The grouping order is determined by the order of the added fields.
