Hello fellas,

I’m new at ERPnext and struggling with Supplier Quotation.

What i want ? I want to calculate sum of each supplier quotation items weight. I already added weight to each item. Now I’m trying to solve “Calculate sum of each weight”.

Where is the code of this section. in Javascript and Python whatever.

Can you give me suggestion of how to solve this problem?

Thanks.
