Because I don't have a version old enough. Old enough to open, not old enough to alter design without converting. Can't convert because....well, you know why.
I think it is R-std_employe_perteT_emballage_P2_final
I'm not confident that this will be the problem because the query runs anyway. I've never seen so many objects in one db. I don't speak French at all really, but I think I can grasp enough that it sure looks like there's a lot of unnecessary duplication in everything, and that's adding a lot to the high degree of difficulty here.
Since I last wrote I've been working on a way to loop over controls in forms to check their recordsource but it's quite complicated and exacerbated by the sheer number of objects. After form controls would be done, if the issue isn't found, then what? Reports? If you don't know what I mean by that, then consider that a form control has a recordsource. If that recordsource is a little query that's only native to the control (such as a combo or listbox list) you won't find it in any query. If it's an expression like =DLookup("description", "FieldNameHere") you'll never find it in a query either. Nor will you if it's on a report or form where the control =[someField] & "," & [description].
I've been at this for about 2 1/2 hours now (mostly trying to loop over forms and their controls) and I'm not sure how much time I can devote to this. It would be different if this were my db and my job, but there is only so much one can do with his free time. You might have to methodically delete (in A DB COPY) say, 10 forms at a time and note which ones you did in a batch, then attempt to convert. Keep going until it works. If never, then continue with reports, same idea. If it never works, then forms, attempting to convert after each batch. Once it works (if ever) you will only know that it is one of the last 10, then will have to start over with a new copy and delete 1,2 or whatever you like, testing as you go until you narrow this down to one. Then you know what to look in, but I'm not sure you know what to look for.
Having said all that, I recall you said it would convert after removing one query and I asked which one that was so that I could try it, but I don't recall getting an answer. See post 26...
