How can I read the data in different Deployment Unit、

Hi experts,

In Bydesign system, the Deployment Unit of Solution A is CUSTOMER_INVOICING, and the Deployment Unit of Solution B is FINANCIALS.
I created custom business object bo_A in Solution A, and created custom business object bo_B in Solution B.
Now I am in Solution B, and I want to read the data from bo_A using ABSL, not write, how can do it?

Best Regards,

Benny
