I just managed to get what i wanted but there is still one problem
As you can see I have created a custom field in sales invoice called “TYPE” which is a dropdown list.
Now i want only invoices containing specific items of that dropdown list custom field.
For example, if my custom field contains A, B & C, I want invoices with only A to appear
I have created a drop down list custom field called “TYPE” in sales invoice which differentiates each invoice on the basis of B2B/B2C, Local/Inter State and Taxable/Exempted
B2B LOCAL TAX
B2B INTER TAX
B2B LOCAL 0%
B2B INTER 0%
B2C LOCAL TAX
B2C INTER TAX
B2C LOCAL 0%
B2C INTER 0%
It looks like this after creation of custom report
