Hi,
Do the reset settings at transformaitons. set as overwrite fucntion and activate transformations/dso.
You set order as key field, if same order was repeated then kf will be overwritten.
If not happening then try to add other info obejct to key fields(which will ahve same values along with order) which can make sense and later check it.
After the data to load to dso, ahve you activate data?
Thanks
