I have a document library with a column that I use in the group by. It has only 2 values in the column. After I have created the grouping and I start to upload documents i can only add one document per group. It checks it out to me and after I have filled in the required fields and try to check it in, sharepoint informs me that the value already exists in the list.
I'm confused. Why isn't it letting me check in more than one document per group?
