Output display issue in Vendor Payment using F110

Hi,

My requirement is to trigger a mail when Vendor Payment is done via F110. The issue in my case is,

Case1: Without maintaining receiver address, and performing F110.

                    Here Spool is generated, complete output is displayed.

Case2: Maintaining Receiver address and performing F110

When I maintain a receiver mail address in the vendor(xk03) and for mailing purpose I have maintained in SCOT tcode. Here when I perform F110 to run the payment, mail is getting triggered in SOST, but only half of the output is displayed remaining half is displayed in spool.

For example: Output has 2 pages to be displayed, in this case, only first page is present in SOST and 2nd page is present is Spool.

If remove the mail address from the vendor, proper output is generated in spool.

I havent come across such scenarios, kindly provide your valuable inputs.

Thanks & Regards,

Karthikeyan G.
