What is the difference between BT and ONEORDER?

[former_member598172]

When I have the lv_bol_core (from cl_crm_bol_core) and execute start_up("xxx"), I often see BT or ONEORDER the param input. As I am still a rookie within the BOL entity topic: What is the difference between them?

Hi,

START_UP receives a Component Set name, which both BT and ONEORDER are.

Component, simply put, is a representation of a Entity model. There is BP Component for Business Partner model (with includes Business Partner, Business Employee, and its direct related data like address, telephone,...) , BT for Business transaction model.

Component Set is a set of Components (that was easy). Almost always a Component only doesn't provide much use to write a useful application, so a Component Set must be properly selected (or created).

Sometimes a relationship between entities only are defined in a specific Component Set. ONEORDER contains both BP and BT Components, so you can check Business Parter data right below BTPartner Entity, where BT Component Set contains only BT Component (I think, without a system to check right now). So, yet BTPartner holds a Business Partner, it will not show a BusinessPartner node when using BT Component Set.

You can check that in GENIL_BOL_BROWSER.
