Hi to all,
in the BW SYSTEM of my new customer happens that the delta loading of the standard extractors is slow compared to the number of recrords trasferred and very slow compared to full loading.
Just think that to load 5 records in PSA from a Master data extractor it need of 7 seconds in full mode and 32 minutes in delta mode.
For two particular extractor ( 0cust_sales_attr - 0vendor_attr) the loading of 2 trasferred data lasts 39 minutes.
I notice that the difference between the operation of "data selection scheduled" and "record sent" ( for 2 records) is 30 minutes.
Assuming that :
no IDOC blocked in both system ( SM58);
the check in the source system with tcode RSA3 maked on the same datasources is very fast.
the full loading on the same data is very fast. the server processor is completely empty (SM50). the process we talk abou contemplate only the dataloading on the PSA.
Anyone have an idea to speed and tuning this delta mode?
Kind regards
Rino Sica
