"Checks after phase MAIN_NEWBAS/STARTSAP_NBAS were negative! Last error code set: Unknown macro 'FN_WORKPRC' System start failed"

Hello Experts,

We are upgrading our BW NW7.01 system to NW7.3. In the Downtime EXECUTION phase we are getting below error. But the thing is system was not even down.. but still we restarted it manually and system is running fine... but we are not able to move further in upgrade phase, getting the below error.

Checks after phase MAIN_NEWBAS/STARTSAP_NBAS were negative! Last error code set: Unknown macro 'FN_WORKPRC'<br/> System start failed"

Also, attaching the logs for your reference with this message. Please let me know if have any solution/suggestion for this.

Thanks
