• Message class: DMC_IU - DMC: Messages for Integrated Upgrade

• Message number: 005

• Message text: Error while reading buffer file &1

What causes this issue?

Buffer file &V1& could not be read or does not contain data.
Error cause 1: The file does not exist at all or it is located in a
different folder.
The file must be placed within the folder BUFFER of the transport folder
if no other data path was specified (see parameter TRANSDIR of the TP
parameter file).
If a new data path has been supplied, a folder named BUFFER and
containing the buffer files must exist within this directory. The folder
BUFFER is NOT to be part of the new data path; specify just the
data path up to the folder BUFFER.
Error cause 2: The file does not contain any relevant data. For the
extraction, the transport requests are extracted from the buffer files.
No transport requests have been found within the current buffer, though.

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