Batch Job for AR Residual Items

Hi Guru's,

We currently have process in Accounts Receivable where every night some thing similar to a batch job runs for the residual items. I need so change the printer information on this.

At first I thought this a batch job but I am not able to find any batch job for this. I checked in SPO1 and I am able to see a list of output showing these letters.

I am wondering if this is something in config. can someone please help or suggest any idea where I see for something like this ?

Best Regards,

Yasmeen
