st: no error message with - Append - string in one and byte format in other dataset

["Grote, Veit Dr." <Veit.Grote@med.uni-muenchen.de>]

Hello,
I appended to my master dataset a dataset in which a couple of variables (existing also in master as byte) are formated as string. Stata produces no error but solely a note
(note: hzlokal is str1 in using data but will be byte now).

However, it does not append any data but missing values for the appended data. This in my view should produce an error 
message not just a harmless note! Or is there another reason for just prodicing a note?

Best wishes,
Veit
