Rush One Cycle Transaction

Dear Expert,

I am facing this situation in one of our offices. Currently, we are using SAP R/3.

Customer comes to our office and then checks out all the things that he buys. As this happens, we are indeed in a rush time to create one cycle transaction, Sales order + Delivery (also PGI) + Billing, because we need to print invoice form for him.

Is there any settings in SAP standard for Automatically creation of Delivery + Billing ?

It is minority transactions, such requirement, we aren't planning to implement SAP IS Retail.

Or is there any opinions about this requirement ?

Every input is highly appreciated.

Thanks a lot

Charles
