records not getting loaded to DSO ?

All the records except with the movement type 412 are not getting loaded to the DSO from the WO DSO. Both the DSO have the same key. Its really strange only the document numbers are getting extracted and no other information is seen. There are no routines/filter either in the DTP or the start routine/end routine. Please advise.

NOTE  : source is a WO DSO and the Target DSO is a standard DSO but both are with the same key. Do I need to check anything else ?

Thanks
