Hi, yes I know it that's why I wrote to go to the link PR 3588 in Frappe where I put the screenshot, I didn't want to duplicate it because this dev has 2 parts, one in Frappe and another in ERPNext.
Here is the direct link : frappe/frappe#3588

Thanks

I can't re-open the PR because it was not closed by myself, could you please do it ?

Thanks

@mbauskar @rmehta Could you please tell me why you don't want to re-open this PR ? I asked many time and don't know what to do or what you miss. Thanks
