What causes this issue?

In the controls for copying billing document (F2) from credit memo (CR)
or debit memo (DR), the quantity/field value must be ' '. This message
appears if VBTYP for the source billing document is 'M' and if VBTYP
for the target document is 'O' or 'P'. This copying control means that
a credit memo or debit memo is created directly from the billing
document.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
