hi,

for uploading data more than 50,000 you can use both call transaction or session method but execute it in background because it may take some hrs.....only difference between these two methods is ...in session method...u can upload entries in background and the session will be created and according to ur convienience u can execute the session in SM35 be it error mode/display all mode. But in call transaction u have to be sure to be there till the program successfully executes.
