STO with 351 followed by 101

Hi,

We have a scenario where in we need to move stock from one plant to another within the same company code. We are using the STO because certain fees/tax and charges are involved. Currently we post the 351 for the GI to intransit and then 101 for GR although there is no Intransit involved as such. We post the 351 and immediately post the 101. Is there a way to automate the second step which is 101 as soon as 351 is posted. Is there a better way to do this?

Thanks,

Hems
