Hi,

It looks like the issue is due to the fact the function module "SUSR_USER_CHANGE_PASSWORD_RFC" is not

able to change the passwords via RFC.

The following steps have helped in some similar cases:

-

1. Is the system up and running and can you logon with both DDIC and SAP* user in client 000.

2. If yes, proceed as follows:

3. Logon with user DDIC in client 000 and execute the jobs RSWBOINS and RADDBDIFF in transaction SE38, if no errors then procced.

4. Ensure that all sapinst-processes are stopped.Copy keydb.xml to keydb.xml.org and then modifiy keydb.xml as follows:

Look for the string SAPINST_INST_STATUS and afterwards for the

string CDATAERROR replace 'CDATAERROR' by 'CDATAOK'.

5. Proceed with the installation as usual.

If RADDBDIFF doesn't exist, still follow all the steps with RSWBOINS.

-

I hope this helps.

regards,

ganesh.

Thanks for the tutorial.

I tried to install SAP GUI, but i got the following error:

This SAP Front-End Patch cannot be applied. Either the installed components are already on the same patch level or the components to be patched are not yet installed at all.

SAP GUI for Windows 7.20 (Compilation 3) Patch
Patchlevel 8

I checked my system, but there is no installation of the SAP GUI. So whats the problem ?

Hope you can help me out again.

Thanks in advance.

Ok I managed some steps:

The following i done:

1> Close /stop your SAP installation.
2> Install SAP GUI.
3> Start your SAP.
4> Log in CLIENT 000 with by SAP*: Password: 06071992. If this password does not works then try the password which you had provided while installation.
5> SU01
6> Reset the DDIC password..

Step1: successful

Step2: successful

Step3: RSWBOINS -> done, but nothing happends | RADDBDIFF -> doesn't exist

Step4: cannot find the string "CDATAERROR" | there are only CDATA strings

So i dont think the workaround will work for me ? Or do i missed something ?

I found the answer not to work when I encountered the same issue.  After looking at the sappiest_dev.log file I found the following error after the RFC call..

ERROR       max no of 0 conversations exceeded

Then i checked the environment variable CPIC_MAX_CONV, by typing  $env | grep MAX,  the environment variable was set to ""

I changed /etc/profile.d/sapserver.sh  to properly set the environment variable and restarted the server.  Restarted sapinst, and it worked fine.
