The name of your campaign must contain more than two symbols.
Make sure you will be able to identify the campaign by its name later in the reports.
Examples of good names:
New swimsuits 189 pcs acos=18%
Best Sellers 2017-18 150 pcs acos=12%
T-shirts 200 pcs acos=15%
The campaign name can't be changed after it has been recorded in the system.
