Closing Requests Using Process Chains 

Use

When you transfer data using a Web service or real-time data acquisition (using a SAPI and a Web service), the InfoPackage requests (also called PSA requests) remain open across several load processes. The requests are closed when the threshold values set in the InfoPackage are reached. The system opens new requests and data transfer is continued using the new requests. With process type Close Real-Time InfoPackage Request, you can close an open PSA request before the threshold value is reached.

This means that you can use a Web service DataSource to send data to the PSA in BI and then use a standard data transfer process to update it further.

You can close requests in this way to perform regular analyses at set times on an InfoProvider that is down stream of a DataStore object that you are using for real-time data acquisition.

Procedure

...

       1.      In the process chain, choose process type Close Real-Time InfoPackage Request.

       2.      On the next screen, enter a technical name for the process variant and choose Create.

       3.      On the next screen, enter a description for the process variant and choose Continue.

The maintenance screen for the process variant appears.

       4.      In the table, select the InfoPackage for which you want to close a request.

       5.      Choose Save and go back.

Do not schedule this process to take place more frequently than once an hour, otherwise performance is affected. If you schedule the process to take place more frequently, the system may generate so many requests that performance is affected.

Result

When the process chain is run, the system closes the PSA request, the DTP request and the change log requests when the start event is reached. The process chain does not wait until data is loaded; it closes any empty requests and ends the process with status green.
