I'm not aware of any manual that lists ACIS errors, I suppose only developers get that info.
You didn't say what tool and options for the tool that you are trying to use so I can only speculate on your situation.
Vectors are relative points, say you want to extrude a part to the same height as another part. Select "Extrude Solid" by Vector, select the part to be extruded then click on the bottom corner of the other part, then the top, the two parts will now be the same height. If you clicked on the bottom corner as the start point and again as the end point, your vector would be zero length and cause an error. I was able to extrude all the elements in the posted drawing using both by distance and vector.
One other thing to be aware of is if you extrude all four objects at once the four parts will be considered as one, so extrude each part separately.
