I am working with SPM extracting data from one of our R/3 systems (R/3 4.7). I installed the extractors in our system, copy the existing project delivered by SAP and then generated the extractors for those objects that we need. My question is regarding deltacapability. I read delta is available for some objects, based on their creation, posting or last change date. Nevertheless I cannot make any of them work in delta mode (even for those where there is a date available for delta extraction, for example Cost Centers, Invoices, POs.). I go to transaction Z_SA_EXTR, select project and object, and then click on Start. I immediately get the message 'Object file created successfully' (what is true, the file is there). But I am never asked whether I want to execute it in full, init or delta mode.
The SPM application will be installed in a standalone server (not in any of our existing BW systems), so I will be generating flat files to be FTP to the final destination. Is it that if I do not have a datasource for BW the delta mechanism is not available?.
Please clarify me on how this works. Many thanks!
