Difference in number of data records

I have uploaded data from R/3 to BW (Controlling Datasources).

The problem is that when i use the extractor checker (rsa3) in R/3 for a
specific datasource (0CO_OM_OPA_1) it shows me that there are 1600 records.

When i load this datasource in BW it shows me that there are 400.000
records. I'm uploading data to "PSA only".

Any ideas why this is happening ?

Thanks

Check the 'data recs/call' and 'number of extract calls' parameters in
RSA3. Most likely the actual extract is only making one call with a larger
data rec/call number. The extraction process will collect data records
with the same key so less data has to be transferred to the BW. When you
run RSA3 you are probably getting similar records (that would normally
collect) in different data packets thereby creating more records. Try
running RSA3 with a much higher (2000) recs/call for several calls.
