Hi Amit,
this issue is posted in the wrong area. However, you can take a look the following on your system and see if they are possible, I copied this information from customer messages submitted to SAP so hopefully it helps...
"if you look in txn /SAPAPO/SDP_EXTR for datasource 9A**** you see
that parallel processing profile Z_PARAL009 is assgined. As per
definition of this parallel processing profile 8 parallel processes will
be used."
please check to see if you have a similar parallel profile in your source. Also, in each case I checked it seems to be dialog processes being used, not sure why.
Hope this helps, you might have more luck with the 'dataservices' discussions,
Colm
p.s. generally you can maintain control parameters between a SAP source system and BW in the following location...
-> source system
-> TA SBIW (Data Transfer to the SAP Business Information Warehouse)
-> General Settings
-> Maintain Control Parameters for Data Transfer
But I don't think this is relevant to your issue.
