Access the
Web Dynpro Content Administrator
under
Log on using the administration user for the J2EE server.
To create the required JCo connections or edit the existing ones, choose
Maintain JCo Destinations.
A list of the JCo connections for the metadata and those for the application data is displayed. Connections for various areas exist. The names of the connections start with
SAP_R3_*
.
Example
JCo connection for metadata:
SAP_R3_HumanResources_MetaData
.
JCo connection for application data:
SAP_R3_HumanResources
.
Note
If the software is already installed on the J2EE server, the
Web Dynpro Content Administrator
automatically recognizes which JCo connections are required.
Configure the JCo connection for the metadata :
Consider the language settings. Set the appropriate language.
As the
Connection Type
, choose the
Dictionary Meta Data
option.
Choose
Security
.
In the
Used Method
field, enter
User/Password
.
Enter the user in the mySAP ERP system that you created for the metadata connection.
Enter the password for the user.
Check the connection.
If the user only has the authorizations from the S_DDIC_MDI profile, the system issues the following error message when you check the connection:
com.sap.mw.jco.JCO$Exception:(104) RFC_ERROR_SYSTEM_FAILURE: No RFC authorization for function group SSCV for user <your metadata user>
.
This message does not mean that the specified user does not have the required authorizations for the metadata. It means that the user’s authorizations are not sufficient to test the connection.
Configure the JCo connection for the application data :
As the
Connection Type
, choose the
Application Data
option.
Choose
Security
.
In the
Used Method
field, enter
Ticket
.
Check the connection.
To check the authorizations, the system uses the administration user for the J2EE server with which you are logged on. If this user does not exist in your ERP system, the following error message is displayed when you check the connection:
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Unable to check the issuer of the SSO ticket
.
