Example - If control Exist

hello Folks,

to give a background, I am modifying Iw32 screen.

There is a functionality to do the TECO inside the screen and I am copying it to the main IW32 screen.

In few cases where the ORDER Is perfect, there is a popup and then press OK . TECO is takes place.

SO script is like below-

1) Open order

2) Press TECO.

3) Press OK ( for Popup).

In case if order is not perfect, it shows "Warning Message" in the message tool bar - but only in GUI .

now as my script is running all the three steps it shows "CONTROL not found "

I am trying to find any example of how to write control not found in SAP personas 3. SP2
