Hi taniya,
since you are not getting dat ain rsa3 itself, please confirm if there is any data in the ECC for the tables these extractors are picking data from. You can get info from help.sap on which all tables are used.
for eg for 0FI_AR_5 the table is KNB4, check if there is data in this table. also try to get confirmation with someone from fi team on ecc side that FI data is posted in the system
Regards,
Rathy
