This requires that no jobs or purchase orders, etc. are in add/edit mode or adding that stock code whilst you are changing some of that stock's core fields.

Locking will occur even if the particular stock code is not involved in a job, purchase, etc. at the time.
This type of amendment must be done when there are no other users logged on. |
Example 1
Stock is Serial On sell. Someone is adding job, adding that particular stock, adding serial numbers, and whilst this is happening you change the stock to Serial not required.
Example 2
You are editing the stock when someone adds a job with that stock and invoices it. You change the GL group and finish editing the stock. This will have consequences on Accounts.
The only way to be 100% sure is that, on saving the stock, nobody is adding/editing at the time (eg. no locks) and there are no stock transactions for the stock.
