How do I run a report on line items in quotations?
For this requirement you can create a report in Zoho CRM where you can choose the "Quotes" module and "Products" as the related module.
Now choose Summary report --> select fields such as product name , quantity, quote number and subject etc..
Select Grouping Option and choose "Product name" as "Summarise information by" and run the report.
Here you will be able to see the products (grouped count) and number of quotes the product is associated to which lets us understand what products are being quoted and what quantity is involved.
