BW4Hana Extraction job in ECC

Hi friends,

We are facing a issue with using the the DS: 0UC_SALES_STATS_02 due to huge data especially with some of BW extraction jobs in ECC are seems to be taking much longer time .

The system organise the data on packages. the parallel processing in BW4hana doesn't take too much time but in the opposite it takes too long time in ECC. Is it possible to run them in parallel processing in ECC?.

Many thanks in advance for your help.

Regards
