When Save All is selected in assy, SW tries to save toolbox components like screws etc. (which are read only thus can't/don't want to).
Can't turn this off as before. Makes it very hard to save/update complicated assy if using toolbox items.
Tools > Options > External References and select "Don’t prompt to save read-only referenced documents (discard changes)"
Would have assumed this would do it like before as you suggested
However, still tries?
In that case select the first option too "Open referenced documents with read-only access"
After OK get same thing..........I thinks this is a bug!
I don't have have access to SW2016 SP 0 right now so can't verify. But please go ahead and submit to your VAR.
We are having the exact same problem with 2016 SP3. Open an assembly, drop some toolbox fasteners in, save as an assembly, then save-all, and it pops up wanting to save-as for each and every toolbox part. This wasn't a problem in Solidworks 2014.
It seems that this is a bug specific to 2016 version. I tested also in 2015 version and it works correctly. No "Save As" interface displayed.
There is a SPR for this no 920731 but it is not specified the SW version affected by this bug.
