SAP IBP - RTI; Navigation to other Systems

[Crombach]

Hello everyone,
in Order Based Planning / Real Time Integration it is possible to integrate several external systems in one planning area.

So that the system can distinguish the product ID, IBP adds the logical system to the product ID.

See:
https://help.sap.com/docs/SAP_INTEGRATED_BUSINESS_PLANNING/68fa1e86fe6f41d98421d1ce13a08a9f/fcfae209...

Example:
Prd-ID S4: FG126
Prd-ID IBP: FG126@COE

This link can be seen in the app: “Product Mappings - Real Time Integration”.

Now to my question:
I would like to jump into the S4 system via the Planner Workspace. There are also best practice instructions for configuring this.

When I implement these, the system jumps to the source system, but opens the selected app with the IBP product ID (FG126@COE) and not the product ID of the source system.

How can I change this so that the system selects directly with the correct product ID?

I have tried to change this with the help of an additional attribute in the planning area and by changing the source attribute in the Dynamic Attributes section in the Manage Navigation to Other Systems app. However, this means that the navigation option is no longer displayed in the Planner workspace. If I undo the change in PRDID, the navigation option is immediately available again.

Many thanks for your support
