Extarctor 0CO_OM_CCA_10

the extractor 0CO_OM_CCA_10 was set as a delta load some years back and from 3 months time, somebody has set the processing as "till PSA", which means before 3 months all the delta requests are loaded to PSA + DSO

Now, from the past 3 months, requests are loaded till PSA and never updated to DSO

Now, if i need to get the data, i've deleted the Previous INIT flag and made an "INIT WITH DATA transfer" option.. the data load is successful, but the request activation in DSO has failed, pointing the 3 months OLD Requests, which loaded till PSA only

Now, what should i do, the request in DSO was not activating due to the "OLD requests of PSA which werent loaded"

I am even unable to Use "INIT WITHOUT Data transfer option ", as this option is greyed out

please suggest what needs to be done
