Hi all,
after studiyng the documantation regarding filedmasks, I am stuck and would like to ask the forum.
I would like to create a fieldmask for invoicenumbers. The mask should only accept numbers and alphanumeric AND only - (Character minus) as separators, no space, no underscore or other characters. The entry could be something between 1 and 100 characters. Minus is allowed no time, one time or multiple times. Any ideas?
e.g.
These should be valid data:
RE-1234-56-789-0
123-AB-12-INV
123456789
ABCDE
2019-01-19-ABCD
