please help me to solve this

Hi welcome to ERPNext,

To learn about permissions check this https://erpnext.org/docs/user/manual/en/setting-up/users-and-permissions.

In the subject line I corrected a spelling error, to help with general searchs.

I ran into this error also (it might be a bug). I WAS able to create single variants and since I only had 5, I just did them one at a time.

but iam not able to create multi variant for non numeric attribute , Single i can make no issue, but for multivariant i need solution ???
