If you want data transfer to BW (master data or transaction data) to be controlled externally, as opposed to being requested by BW, and do not need to refresh data more than once an hour, use the Web service with standard update to transfer data to BW.

PSA requests for Web services remain open across several load processes. You can only update data using a standard data transfer process if the request is closed. In the InfoPackage for real-time data acquisition, you specify the size and time limits for closing the request. To schedule data update using a standard data transfer process in a process chain, however, we recommend closing he request using process type Close Real-Time InfoPackage Request as described below. When setting the threshold value, therefore make sure that these settings allow the request to be closed using the process type.

Add any other processes you need to the process chain.

When the Web service returns data to the BW, it is posted to the PSA table in an open request.
The scheduled process chain waits for the start event. The start event triggers the event to close the PSA request. When the Web service sends data to BW, the system checks whether the start event that closes the open request has been triggered. If this is the case, the Web service caller closes the request, and the data transfer is performed using a new one. The closed request is posted to the InfoProvider using the data transfer process. Data is available for further update and processing or for reporting and analysis purposes.
