Hi,
Thanks for you valuable suggestion.
No this message not repeted any more.
I saw the below error
[IBM][CLI Driver][DB2/AIX64] SQL0438N Application raised error or warning with diagnostic text: "SQL0438N Application raised error or warning with diagnostic text: "C". SQLSTATE=55555
showing CLI driver so thought it may be related to Client upgrade
I will talk to SAP basis admin(Don't have access to DBACOCKPIT) for this and will raise OSS if required.
Btw any more information will be highly appreciated
