When trying to repeat the chamfer function on several footprints of a part under SW14, the operation is blocked by the software displaying the following error message "construction error: some chamfer objects are no longer in the model, edit the function to re-select the objects",
Knowing that the material removal function (bevel base) was done with the same repetition and dimensions, see the attached overview.
If you really have difficulty, sometimes the repetition goes better by doing face repetition and for this you have to select all the inner faces of the material removal (including the chamfer).
Thank you for your answers, the 3 solutions have been tested, at first I wanted to do a single repetition for the material removal and the chamfer (plus a drilling) and it's practically the same phenomenon, checking the geometry repetition doesn't work either.
I tried to redo the manipulation on a simple part, to make sure that there is no dimensional error on my thing, but it didn't do it too, see the preview
A solution to do this chamfer repetition afterwards, even if it is far from being the "cleanest" would be to do the chamfer with a removal of material by sweeping.
This is a limitation of SOLIDWORKS, it is impossible to repeat a chamfer, fillet, or draft alone because these functions are dependent on parent functions for the definition of faces or edges, the only solution is to repeat this chamfer in the same repeat function as material removals.
FYI, this is documented in the SOLIDWORKS KB under the reference: S-00921
Indeed, I tried the manipulation again on a new part and it works again!!
I think what was blocking me was that the sketch of the material removal was not on the same plane on which I put the chamfer, once I put them back on the same plane, it worked (but limit, the repetition is done along a single Axis : s)
