extraxtion from 2 data source to 1 info cube

hi all,

i use COOM_C02 info cube and i extract from ;

-0CO_OM_CCA_9 Cost Centers: Actual Costs with Delta Extraction

and

-0CO_OM_OPA_6 Internal Orders: Actual Costs Using Delta Extraction

in the monitor i see that the extractions are succesfull. i can see all the data in PSA for both extractions. But when i look the data of the cube there are only 0CO_OM_CCA_9 data. I can't see the data extracted from 0CO_OM_OPA_6.

what's the problem might be?

urgent! please.

thank u.
