Transaction IW39 is used to display the Plant Maintenance Orders .

Output will be IN ALV . List displayed in the output screen should be refreshed automatically without any manual intervention at regular time interval .

Kindly suggest ...

Hi,

You can use the method check_changed_data:

CALL METHOD alv_instance->check_changed_data

IMPORTING

E_VALID = l_valid.

The flag l_valid indicates if there is a change in the internal table used to display the data in the ALV.If the flag is checked,then you can call the method REFRESH_TABLE_DISPLAY.

CALL METHOD alv_instance->REFRESH_TABLE_DISPLAY

...

Hope this helps.

Hello Durai,

The methods that I have mentioned can be used in your program for a similar requirement(where you went ALV data to be refreshed).However,the transaction IW39 uses a standard report.No changes can be made to this particular transaction.You can refresh the contents in this case only by using the refresh icon provided in the tool bar(the 3rd icon).
