Task Scheduler problem-Running bat files that writes to mapped drives

i tried running bat file manually , works ok. bat file runs java class detects folder exists , write file mapped drive(z:/) , has permissions enabled full control authenticated users.

however, when use task scheduler run bat file, seems not detect path.

would know how can make task scheduler run bat file such can write files on mapped drive?

does batch file reference drive letter or unc path?  user account configured run task doesn't have drive mapped.  utilise 'net use' command inside batch file map drive.  syntax of command is:

net use
[devicename | *] [\\computername\sharename[\volume] [password | *]]
        [/user:[domainname\]username]
        [/user:[dotted domain name\]username]
        [/user:[username@dotted domain name]
        [/smartcard]
        [/savecred]
        [[/delete] | [/persistent:{yes | no}]]
net use {devicename | *} [password | *] /home
net use [/persistent:{yes | no}]

or reference unc path in batch file instead of drive letter.
