Good Evening Tina,
I have done the proc compare and there are two observations which are not equal. Observation number 5 and 37. In my output data set Epoch Treatment is assigned to observation 5 and in your data set it is Screening.
I am modifying my code for observation 37 Epoch as with regards to RFENDTC your assigned Epoch is correct.
I will get back to you with final compare as soon as possible.
Thank you and regards
Amruta
