We use ERPNext Cloud for work where we administer two different companies and have a local instance using Virtual Box where we test features that we would like implement.
We have noticed some differences between these two instances.
For example, both instances have the same Default Company in Global Defaults. In the local version of ERPNext whenever a new Sales Order is created (or any other document that has the Comapny field), the chosen Company is the same as that of the Global Defaults. However, in the ERPNext Cloud instance this is not the case and the Company chosen by default is always, independently of the Global Defaults, the company chosen when we first signed up for ERPNext Cloud.
Here’s another example that I have described before about differences between the two instances.
Both instances are now running ERPNext: v9.1.6 (master) and Frappe Framework: v9.1.9 (master). However, we have noticed these discrepancies when we were running v8 as well.
