SAP CPI Message Mapping: Mapping two source lists to one target list

[aparr]

Hi all,
I've created a message mapping to map values from a source structure to the needed target structure. The source structure has two lists with a different structure, which shall be merged into one target list.

I can assign values of one source table to the target table and everything works as expected. When I try to add the second table I can't connect connect it. How can I achieve such a scenario with SAP Cloud Platform integration?

I'm using the Web Frontend of SAP CPI on NEO EU1 with Build version 2.51.11.
