Where did the BAPIs go?
If you have used the WCF SAP Adapter prior to Beta2, and then switched to the Beta2 version, one major difference is visible during the Metadata Browse and Search experience - The BAPI node is no longer visible!
No, the adapter has not stopped supporting BAPIs. Instead, (due to non-technical constraints), we've decided to not show the BAPI node by default. BAPI visibility during design time, and execution at run time, is now controlled by a Binding Property named "EnableBusinessObjects" (which you might have guessed by now - is false by default). Therefore, you need to ensure that this property is set to true during both design time and run time if you want to use BAPIs.
Another enhancement - it is now possible to have BAPI_TRANSACTION_COMMIT and BAPI_TRANSACTION_ROLLBACK exposed within the same proxy object. Earlier, due to an oversight on our part, the BAPI methods were exposed in one proxy interface/contract/object, while the Rollback method was exposed in another proxy object - which meant that BAPI calls executed on a different SAP connection as compared to the Rollback function. This defeated the whole purpose of Rollback - the rollback needs to happen on the same SAP connection on which the earlier BAPIs were executed.
