Marking a dimension as line item
FI Document number 0AC_DOC_NO does not have any master table or text table as it is just storing the number. Therefore no SIDS exists. Now when i insert this in a cube, will it be a good idea to mark the dimension as line item. Will it make any sense as the data load performance is affected when creating SID's. What will happen in this case. Will marking it as line item still save time on creating DIM ids.
