Solution

Most probably the issue was due to below,

The environment variable for SECUDIR is not set
The cred_v2 file issue
- Missing file
- Missing credentials

You can refer to this SAP Note 1525059 – Troubleshooting problems with PSE credentials for more details.

Check and verify:

The environment variable SECUDIR is correctly set for the active user.
On UNIX systems: the environment variable USER is correctly set for the active user.
The container file for credentials (named ‘cred_v2’) is found in the directory indicated by SECUDIR.
A readable credential exists for the active user for the PSE in question.
The credential contains the correct PIN (password).

Commands for credentials maintenance:

##Run some basic checks, display the installed patch level of 
##SAPCRYPTOLIB/CommonCryptoLib as well as the current setting of 
##environment variable SECUDIR:

sapgenpse

##Check (list) credentials and display the active user:

sapgenpse seclogin -l

##Remove (delete) credentials:

sapgenpse seclogin -d [num] -p [PSE file name]

##Add credentials:

sapgenpse seclogin -p [PSE file name] [ -O [OS user name] ] [ -x [PIN] ]

##Show the full list of parameters (help):

sapgenpse seclogin -h

##Check the credentials as the system "sees" them by executing 
##the following command in report 'RSBDCOS0' (in transaction 'SE38'):

sapgenpse seclogin -l 2>&1
