Tried to search the forum for the issue but did not find any relevant post, hence posting this.
We are using ERPNext v10.1.81 in self-hosted production.
While adding a sales invoice, any items we add do not get the HSN code already added to the item master. Is this a bug or is it a setting which we missed.
Also, warehouse in Stock Details remains blank and we are forced to select for each row. Ideally, we expect default warehouse to be pre-filled.
Issue was due to fetch_from not being set in Custom field for gst_hsn_code. I suppose some patch should update the custom field and move option value to fetch_from
