Hi,
you already run the init and your are trying the one more init then you got error.
plelase delete the init request form the info package scheduler mentioned by raman.
then run the info package with init.
after deleting the init check the data source in RSA7 and after running the info package check the init in RSA7 for specific data source.
again the run delta info package check the how many entries in data source in RSA7 same records are transfer to BI psa.
Thanks,
Phani.
