Overview
You can use this account type to connect SAP Snaps with data sources that use SAP JCo account. The SAP JCo Account connects to an application server (ASHOST - Application Server Host). Learn more: SAP Configuration.
Ensure that your SAP instance is configured to work with the Snap Pack.
Prerequisites
None.
Known Issues
In version 4.28 (main14627), the SAP Snap Pack's bundled JCo library was upgraded to 3.1.4. Prior to that, version 3.0.6 was used.
In version 3.0.21 of SAP:
The default login behavior of the JCo library changed.
The default value of property
jco.client.snc_sso
was changed from 0 to 1 (enabled).
The above changes will impact your pipelines if you use a username/password for RFC login. Login would work with the SAP Snap Pack versions before 4.28 but will fail with versions 4.28 or later.
The following workarounds can help mitigate the issues:
Add the
jco.client.snc_sso
JCo property with a value of0
(disabled). If the account still fails with a "Name or password is incorrect (repeat logon)
" error, even after adding this property, then reach out to the SAP team to enable the option "Permit Password Logon SAP GUI" for that specific user.Select the Permit Password Logon for SAP GUI (User-Specific) in SAP portal.
The permit password option is effective only if the profile parameter snc/accept_insecure_gui
is set to U. (Unsecure login is permitted for specific users).
Limitations
None.
