ALV Report Refresh Timely

Sometimes we need a report which will be updated timely and the output screen will reflect with the updated data. In production department we need this kind of approach which displays timely updated data for production control. In the following example we have developed a custom table and the table has been populated data in different time. The report fetches data from that custom table and displays output in ALV. Now whenever data is updated into the table the report will display the updated record after a particular time slab. This is very useful when we deal with transnational data.

Create a table as follows:

The table contains one line of data.

The program is as follows:

REPORT zsr_test NO STANDARD PAGE HEADING.
