If I try making a New Quotation for a Lead, I’m unable to select a Shipping Address for the Lead manually, with the error “Please enter Customer/Supplier first”.
Thanks for reporting this issue. I was able to replicate it in my test account as well. We will update you when this issue is resolved.
For now, re-select Lead in the Quotation after adding Address in the Lead. On re-selecting Lead, address will be fetched automatically in the Quotation.
9 years later, still the same problem.
After selecting customer in Sales Order I get:
Please enter Lead / Customer / Supplier first
One solution is that after error you can select customer again and it will work. I have also noticed that if I reinstall the problem is gone. But on my production database problem persists. Even after migrate and clear-cache. So it must be that database got corupted with one of the updates.
