problem in authomatic creation of many house banks

dear all,

i need to create many house banks.

I don't know any standard programs, so i create a LSMW that simulate transaction FI12.

LSMW generates a batch input session, the execution of b.i. is ok but the bank has not been created. It seems that the problem is due to the fact that creation of house banks terminates with generation of a transport request.

Could you please help me to solve lsmw problem or tell me another method to create many house banks?

Thanks.

Elena
