ImportError: cannot import name update_item_projected_qty

when running bench update we get the following:

File "/home/erpnext/frappe-bench/apps/erpnext/erpnext/patches/v7_0/", line 5, in execute
    from erpnext.stock.doctype.bin.bin import update_item_projected_qty

The usual advice is to run ‘bench update’ again


the above warning can be ignored (apparently)

Thank you for your response.

We tried bench update with and without --reset but still get ImportError, it seems there is a problem when executing:


We could try to skip the patch, but as @rmehta stated here, it is NOT RECOMMENDED:

Well the import fails since this method update_item_projected_qty is not present in

That method was added with this 14 April 2016 commit

The question is what became of that method since then, which commit removed it etc and why?

Then will it be solved in an upcoming version? Should we raise a github issue for this?

Yes probably report it on github.

I can’t grok why that method is missing, whether or why you are an isolated case?

I have no current environment of my own handy right now to troubleshoot…

An update - on 13 Feb 2018 update_item_projected_qty was removed with this commit

on this basis

FTW I found the commit only by manual inspection; I tried but could not find it via the command line with for example this:

frappe@ubuntu:~/frappe-bench/apps/erpnext$ git log -S update_item_projected_qty ./erpnext/stock/doctype/bin/

as advised here

edit: a working example

I have pushed a fix to hotfix branch to remove the patch. It will be released to master soon. But as of now, you can comment out the patch from patches.txt and go ahead.
