JCO Connection in MII 12.1

329 Views

Hi Guys,

Can anyone tell me how to connect SAP R/3 using Connectivity type JCO in MII 12.1

I have given the SAP R/3 User name and Password in Credential Editor and other details in System Connection Editor.

And also tested it in BLT using JCO action block. It is showing error has "User Name or Password is incorrect" But the same time tried it in SAP Logon using the same USER NAME it is accepting.

We also tried clearing the JCO Cache using http://<server>:<port>/XMII/JCOProxy?Mode=Reset i got the error as below.

<FatalError>JCOProxy error: com.sap.sql.log.OpenSQLException: Failed to set the parameter 1 of the statement >>SELECT * FROM XMII_CredStore WHERE CREDKEY = ? AND CREDTYPE = ?<<: Cannot assign NULL. The setNull() method can only be used in the VALUES clause of an INSERT statement or in the SET clause of and UPDATE statement.</FatalError>

Can anybody please help.

Regards

Muzammil
