set a Central ESR between CE and PI

[rodrigoalejandro_pertierr]

The objective of this document is guide you through the configuration to set a central ESR in those cases where you have more than one Netweaver Solution.

In this case i will focus in the step where a CE and PI systems are involved.

as every one of us know,Enterprise Services Repository (ES Repository) is delivered as part of SAP NetWeaver Composition Environment (CE) and SAP NetWeaver Process Integration (PI). Now if you have an installation of SAP NetWeaver CE and PI in your system landscape, SAP strongly recommends that you maintain all your design objects in a single ES Repository.

Use the procedure below to set up either the SAP NetWeaver CE or PI ES Repository as the central repository in your landscape. Depending on the scenario, you can run a wizard, which automatically disables one repository and reconfigures the other as the central repository. You can run this wizard only from the SAP NetWeaver Administrator on CE.

Remember that previously, this configuration was manually, now a Wizard is available to avoid that.

If you want to configure the CE ES Repository as your central repository, the  wizard performs the following steps:

• Disables the ES Repository on PI
• Connects the ES Repository on CE
• Creates the PI service and content users on the CE system
• Performs post configuration checks

When you want to configure the PI ES Repository as the central ES Repository, the wizard performs the following steps:

• Disables the ES Repository on CE
• Connects the ES Repository on PI
• Removes PI service and content users from CE system
• Performs post configuration checks

By default, SAP NetWeaver Process Integration connects to the default ES Repository delivered with it, while SAP NetWeaver CE can connect to

any ES Repository in the landscape. Hence, until enhancement package 1 of SAP NetWeaver CE 7.1, we recommended to use the ES Repository

delivered with SAP NetWeaver Process Integration as the central ES Repository in your landscape.

However, as of SAP NetWeaver CE 7.2, SAP provides the capability to automatically reconfigure your SAP NetWeaver Process Integration to

connect to the latest ES Repository in the landscape. So if you have an installation of SAP NetWeaver CE 7.2 or above version, we recommend

to use the latest version of ES Repository in the landscape.

Also remember that

With PI 7.3, it is not possible to have one ES Repository for both the PI 7.3 dual stack installation and the PI 7.3 AEX (java standalone) installation.
