Sales Invoice reference table (HTML)

Updated the Client Script and Invoice_reference in Agarwal's to get the abbreviation from Company doctype.

agarwals/utils/invoice_reference.py

company_abbr = frappe.get_all("Company",fields=['abbr'])
jv_ac_name +=str(company_abbr[0].get('abbr'))

Client Script :

method: 'agarwals.utils.invoice_reference.get_sales_invoice_references',
            args: {
                doc_name: frm.doc.name,
                jv_ac_name: 'Debtors - '
            },
