Hi SAPTechies,
I am a J2EE & SOA architect and new to SAP. We want to detect and signal changes to data in our SAP ECC6 data. We want to notify another system of these changes. The data can be highly volatile things such as the quantity of a product available. Potentially it could be any of the business data that SAP provides. The changes would typically ultimately be persisted by the equivalent of sql inserts, updates deletes. We can use web services to communicate to another system. But how do we detect the changes in the first place? We have heard of a number of different approaches : code extensions, batch jobs, change pointers, database triggers, ALE, ... My question is: Is there an authorative reference that reviews the available alternative approaches? Preferably it should weigh the advantages and disadvantages of the different approaches, and describe best practice. I really hope you have a suggestion. Best regards, Gerard
