Back ground job scheduling.

Hi,

I have a requirement to develop bdc which will populate the screen of the transaction KKS1 and schedule it in a background. The requirement is, when I will schedule the bdc in background, it will generate another job inside of this for the transaction KKS1. When I am executing the bdc in A, N or E mode it is working properly. but when I am going to schedule the bdc in background it is not creating any subsequent job. Need help.

Arnab.
