UOMMustBeIntegerError: Quantity (1.436) cannot be a fraction in row 1

Hello Guys,

I have this error log recurring every hour for months now. I can’t trace the Invoice producing it, thus have no idea where to begin resolving it.

Error Log:

Traceback (most recent call last):

Any help resolving this will be greatly appreciate.

Just a thought - there’s this but no hard details The counter at Account/Sales Invoice still remains red - #5 by clarkej

Have you identified say the scheduler process?

edit: Find a report or query your database for a list of unsaved pos sales invoices?

Hmmm. Let me look into this. Whats the way to identify this scheduler process?

Thanks for your answer Clarke

You need to inspect one of the logs for eg
frappe@erpnext:~/frappe-bench$ find logs -name ‘*.log’ | xargs grep schedule

What version are you running?

Hello Clarke,

I’m using:

ERPNext: v10.1.4 (master)

Frappe Framework: v10.1.1 (master)

I’m still looking through the logs, haven’t yet identified the one these errors are going to.

You may be on to something about unsaved invoices. I’ll need to pass through the shop sometime on check on the offline invoices, I think a user might have entered a fraction quantity for a non fraction item.

Thanks again.

The POS Module does not properly validate for non-fractional UOMs. The invoice remains stuck in the POS with repetitive System Errors popping up. Instead, the POS should synch these invoices to Invoices List where the “Supervisor” can fix the problem.

I think this is the best way to handle this issue.
