In general we do NOT recommend creating workbooks that contain more than 5000 issues or more than 15 columns.
(The exact amount depends on your hardware and software configuration!)
To avoid performance issues we recommend to use filters.
When creating new workbooks you have the option to create them based on filters.
To create filter, follow these simple steps:
Click “Filter of this workbook” (next to the tabs of your currently open workbooks)
Choose the desired filter or create a new one by setting parameters
Refresh page by pressing “F5”
Next time you want to create a new workbook, you will be able to create one based on your previously created filter.
