Email Billing Document to Customer Question

Hi,

For third-party process, as per standard SAP we use order related billing. Recently, we've got a business requirement where the business would like to send multiple billing documents generated in a day as one email to the customer instead of sending an email for every billing document. I don't know if this can be done in standard SAP or not.

Could someone let me know the options in SAP to meet this requirement?

Thanks,

Maruthi
