With this placeholder you can define an individual date and time format for your invoices.
To set this up, go to Master Data - Financials - Invoices - Accounting Groups and click on the 'Edit' button in your desired accounting area. Then select the 'PDF Template' tab and insert the placeholder ### CUSTOMDATE _ ??? ### into your template (in order to support invoice design, all placeholders that you can use are listed in the 'Placeholder' area).
Instead of the three question marks, you enter here finally your desired date or time format, so that when invoicing the current date or the respective time is always given in this form. The specification of the format is always in English.
