PREP_INIT/DB2_CHECKNOTES_INI failed

Symptom:

SUM phase fails at PREP_INIT/DB2_CHECKNOTES_IN.

Continue with phase PREP_INIT/DBCHK_INI

Solution:

1. Check the log files Checks.txt and Checks.log files.

2. In this case the issue was missing due to the missing DBA tools.

3. Download the required version of DBA tool (DBATL740O11_35-80000794.SAR)  to the exe folder in SUM directory . (Eg - <SUM_diectory>\abap\exe)

4. Repeat the phase, issue will be solved.
