Query master data into custom business object
I need to create custom business object for query Price List from account id and product code.
Just query, not create new one.
Now I've ABSL code to query already but I can't set sales price list master data to my OWL.
1. How to call my custom query to get standard data into my OWL?
2. How to binding data in OWL?
Please tell me some advice or another solution?
