 Subject: Error Z1 128 when posting a billing document
 
 Hi all,
 We are getting this error when posting billing documents (debit or credit notes). The error does not have a text or description that could help to identify what the problem is.  We have just updated our system to EHP4 (ECC 6, support package SAPKH60408). We use digital invoice functionality for Mexico.
 
 Thanks for your help.
