BDC problem

Hi all,

There is one problem in a BDC prgm. The requirement is,

i have a parameter p_sessn (session name) which is assigned a default value : PROC. Now, When i run the prgrm, A session with name PROC is created . Now suppose i have 2000 records, all the records are under the PROC session. Now what i need is: for every 1000 records a new session should be generated for ex: PROC1,PROC2 and so on...

How do i go about this?
