Grouping Data in Reports

Report groups are a flexible way to show grouped data based on one or more certain fields, or even on generic expression, that is, a group can be defined based on the specific column.

Here we will build a report to show the list of 違章案件派查明細表, 審理人員 will be grouped together, that is, the manger (suppose the report is for a manager) will know which violation case is reponsible by which 審理人員.
