Met a problem in Magento 2.0.
For example I need Coupon codes XY001 to XY999, where XY is prefix. When I click auto-generate with preferred length of code (3) it will generate completely random codes something like XY2325 or XY2455, etc.
I didnt see in documentation any remarks on how to generate not random, but A to Z codes.
@Ilia_P Yes that's true, it would generate coupon code on random number not in sequence (like 001-999). In order to generate such code you need to write custom script Or generate programetically
