More Records in PSA COMPARED TO IN DATASOURCE

While working on FI Extraction, when I checked the total number of records for 0FI_GL_4 in RSA3 in source system, It was 799 records.

But when I replicated in BW system and loaded into PSA, then there were 2,105 records ( 912 records in 1st Data Package and 1193 records in 2nd Data Package). Can u please explain me about how these extra number of records came in BW System.

Thanks,

Shruti.
