Hi Aditya,
Check if the below SAP Notes are helpful -
1934057 - SPML check error for JAVA managed system
1758186 - Check Configuration Error when user manually maintained
1953221 - User SOLMAN.DUAL.SAPSUPPORT is not defined in table AGSSISE_ACT_USER
1925088 - SOLMAN_SETUP: Measurement Platform Set Up - issue with users
My guess is that the 3rd one should be helpful in your case.
Best Regards,
Tanmeya
