Download the file ‘Ymass_upload 1’  from above Path and keep it ready.

Execute the program YMASS_UPLOAD which was created in the previous blog post. You will get following screen.

SHMA Memory Analysis

No select the ID and click on display icon you will be able to check the contents stored in the Shared Memory in new window.


SHMA Contents


We can use SHMA as an alternative option to Application Server(AL11) to Mass Upload Excel File data in Background Mode as well as in Foreground mode. we can also check the data inside the SHMA and cross validate if any issue arises.

We have taken an example of Uploading Data in a Custom Table. This can be expanded to Custom Mass Upload program for Master data using BAPI’s/FM in SAP with custom validation.

      As I recall, shared memory is shared within the application server, but not across the application server that make up the instance. If your  instance comprises two or more application servers, then this could be a problem for you.

      You see, you're logged into one specific application server (A, say). When you launch the background job, there's no guarantee that it will be running in the same application server, it could be running in appserver B. You've only written your data to A. The shared memory of B won't have the data.

      For this reason, if I had to deal with your project (which doesn't allow writing files to the appserver), I'd persist the data in a database table. When the background job runs, the last thing it will do is delete the data that's been persisted.

      The background job will be scheduled in the same application server in which program is executed. which is covered in the previous section
