Number of records are difference between DSO and Infocube

Hi everyone,

i have finished to load data from Datasource to DSO and from DSO to infocube.

Datasource: 0FI_AR_4

DSO: 0FIAR_O03

INfocube: 0FIAR_C03

But i got a problem, the number of records in PSA is 5130, the number of record when i check in DSO is also 5130, but when i check the Infocube.

there is only 3100 records. I don't know if the Problem is Setting of DTP Process.

for DTP Process between Datasource: 0FI_AR_4 and  DSO: 0FIAR_O03, the extraction mode is Delta

for DTP Process between DSO: 0FIAR_O03 and Infocube: 0FIAR_C03, th e extraction mode is Delta.

Can you please help me ?

Thanks
