SAP Note 16561 - Element ... missing in MAIN window of layout set F110...

Symptom:

Element 510-x or 610-x is missing for the MAIN window in layout set F110... (cover letter x).

Cause and prerequisites

The customer added method of payment x.

Solution
Method of payment x is not supported in the standard layout set (it is not delivered in the standard system, either). If you add a method of payment x, only you know its meaning. This means that only you can define a logical cover letter in the MAIN window of the affected layout set that refers to method of payment D (e.g. "With the payment carrier/check/note of exchange &REGUH-VBLNR&, we are clearing the following invoices..:"). To show you that no such cover letter for method of payment x exists yet in the layout set, an appropriate entry is made in the error log.
