Hello Ajit Sarangi,
Is your requirement is to display the message along with the traffic signel lights (3 colours namely Red, yellow and green). Based on the message you are displaying on the output it should highlight the respective color and other colors should be there but not highlighted. If yes then you can user application error handling method.
There are set of function modules,
BAL_LOG_CREATE
BAL_LOG_MSG_ADD
BAL_DSP_LOG_DISPLAY
BAL_LOG_MSGD_DELETE
At your initialization you can initialize the message log using
BAL_LOG_CREATE
When ever you come across the message to be displayed you can add the message to Log using
BAL_LOG_MSG_ADD
- during this process you have to specify the type of the message based on that the color will he highlighted automatically
At end of execution you can display the message log using
BAL_DSP_LOG_DISPLAY
- this displayes all the messages using the popup screen
At end you have to clear the log using
BAL_LOG_MSGD_DELETE
Hope this helps. Let me know you you want further information regarding this.
Thanks
Nivash
