MESYS pwd is not accepted ~ Possible Glitch

NW 7.1 SP05

MII 12.2.2 Build 228


ECC 7.1

I have started the SAPMEINT CTC wizard and I am getting an error on the MESYS password.

Validation Error: error during validation : Service execution error; invocation target error when calling method maintainUser in class of component (error message = Name or password is incorrect (repeat logon))

  • SOLUTION *************************

I reviewed NWA UME and see that the MESYS user has been created, but it does not have any of the roles that the installation guide says the wizard will attach to it. I started thinking about how users are created in MII and how they need an initial pwd that must be changed when you log in for the first time. I change the pwd in NWA to a generic (qwe123) pwd knowing I will have to change it in MII before proceeding with the configuration.

Open MII and log in as MESYS and then change the pwd to the pwd you wish to set in the CTC wizard.

Log out and takeover the CTC session in NW

Once this takeover occurs, it will succeed with the pwd and proceed to the next step.


This is not mentioned in the installation guide and I have not found this issue anywhere on the sdn or the web. Is this an issue that SAP is awareof, is this common knowledge amoung the ME community or is this localized to my installation instance?

Also, has ME 5.2 been verified to run wth MII 12.2 and higher or do we need to upgrade ME to 6.0?

    Hello Gregory,

    Please, refer to SAP Notes #1334061 and #1594439 for required software components versions for ME 5.2 and 6.0 systems.

    As to the MESYS password; MESYS user had to be created and its password specified in NWA as prerequisites according to the old 5.2 Installation guides. Not positive about 5.2.7.
