Implement Maintenance Planner Verification Error Changes

Hi,

Maintenance Planner show "Error" in the Verification column for my development system, D01. D01 got verification error due to some components not correctly assigned to product. Based on Maintenance Planner User Guide, I have Verified the Erroneous System (D01) and downloaded MPxxx correction file. Based on Maintenance Planner User Guide, section 2.7.4, I need to implement a system change using SUM.

Questions:

1) Based on Section 2.10.2 of Maintenance Planner User Guide, may I know where should I execute SUM to implement the system change? execute SUM in Solman? execute SUM in D01?

2) Do I need a downtime for D01?

Thank you.

regards,

zl
