BOS

When a particular functionality is required at multiple instances, the user can use the BOS feature to call the same BOS again and again without having to create a new BOS every time with the same input and output parameters.  

For example, a user can use a specific calculation on Product data that is built in another BOS in the current BOS using the BOS block without having to create the calculation again.

The BOS block can be used when an App created in offline mode requires a data sync to be triggered whenever the device is online. This way the logic  from a 3rd party lane (on-cloud or on-premise) is available to on-device lane without creating a new BOS every time.

BOS calling BOS Thumbnail and On Canvas

The BOS can be selected from BOS Service dropdown list. These BOS'es are created in the APM under a particular business function.  The Input and Output parameters dropdown lists will display the parameters of the selected BOS.  The parameters  can also be added by variable mapping. Note The selected BOS exists independently in the APM canvas. It need not be connected to the parent BOS by navigational arrows.
