I am using SharePoint 2013. Is there some limit when you have a list with 5 lookup fields to the Assets Library? My Assets Library has very much files like doc, pdf, jpg, gif, jpeg, wmv etc. There are 10000 files. When I try to create a new item it gives me an error. When I remove one of the five lookup fields it works great. When I remove one of the five lookup fields and add a new lookup field to some other dummy list with 10 items, it also works! So it looks like SharePoint dont like it when I have 5 lookupfields to the Assets Library with 10000 files.
Is this some known problem? And how can I fix this problem because I need 5 lookups to this Assets List.
ps. In SharePoint 2010 it is working OK!
