Problem while running BDC to EA26 transaction

Hi,

I am not able to schedule a Job from BDC recording for EA26.

EA26 is a transaction to Create Bills in mass by scheduling a Job.

I am running BDC to EA26 and populating the values, Job is not scheduling, but it is giving the

Detail Status as

Parameters entered

Activity run executed

If I am running EA26 transaction directely then I can able to schedule the Job.

Kindly help me on this problem.

Thanks in advance
