How To Fix TN734 - Cannot unpack to "DIR_EPS_ROOT/in" (see long text)

TN734 - Overview

• Message type: E = Error

• Message class: TN - Support Package Manager (SPAM) Messages

• Message number: 734

• Message text: Cannot unpack to "DIR_EPS_ROOT/in" (see long text)

What causes this issue?

The files in the CAR/SAR archives have to be disassembled to the "in"
subdirectory of the directory that is defined by the profile parameter
DIR_EPS_ROOT.
In this SAP system, the parameter DIR_EPS_ROOT references the directory
"&V2&". Since the files in the CAR/SAR archive are packed with the
relative path "EPS/in", and the directory that was defined by
DIR_EPS_ROOT does not correspond to the schema "<(><path>/EPS<)>", the
system cannot disassemble to "$DIR_EPS_ROOT/in".

System Response

The files are disassembled to the "EPS/in" subdirectory of the transport
directory ("&V1&").

How to fix this error?

Continue to disassemble. Copy the disassembled files to the
"$DIR_EPS_ROOT/in" directory. In the Support Package Manager or the
Add-On Installation Tool, choose <LS>'Load Packages' -> 'From
Application Server'</>.
If you want to make automatic disassembly possible, change the path of
your EPS directory so that it corresponds to the schema "<(><path>/EPS
<)>", and adjust the profile parameter DIR_EPS_ROOT accordingly.

Procedure for System Administrators

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