I have ID with columns like Localdite,Localtime and so on.
In Screenshot 3.column Angebotene Anrufe means is the call offered or no. In the next column we can see the waiting time of the 57 seconds. Now i need to show this 57 seconds on the first call where angebotene anrufe =1.
In this case 11:13:23. All others should be null. In the last column i have grouped those calls but 57 is showed in each row, and should be only on the earliest call where angebotene anrufe is 1.
