Hi Ramesh,
For both of your queries,i would suggest you to recheck the document using transaction code /n/SAPSLL/CUHD_MR_EXP.
Make sure that the determination strategy is already setup and license attributes match the attributes with the document. If you are not sure about the attributes, document is looking for, check the blocked document log. It will show the the attributes system is looking for.
License attributes are nothing but the details you maintain for the license in transaction /SAPSLL/LCLIC01 like FTO, LU, ECCN etc. Make sure license is active and within validity period.
regards,
Kul Vaibhav
