AutoNumber per group box in crystal report

I'd like to add Auto Number per group box in crystal report. He开发者_JAVA百科re I use Record Number but it increases by group box.

Report View

The AutoNumber will be at the front of Barcode Column. How to set it per group box?

To get an incremental number for each record displayed in a group you need to do use a Running Total Field.

1. Create a new Running Total Field
2. Give it a suitable name
3. The Field to summarize can be any field, in your case Barcode
4. The Type of Summary should be Count
5. In the Evaluate section you need to select For each record
6. In the Reset section you need to select On Change of group and then select the Group Name from the drop down.
7. Place this Running Total Field next to the Barcode field.

This should give you an incremental number for each record in your group.
