Dear @Purushotham9963 ,

'we have many conditions we do not have any space left to give this in the condition field.'

There are 2 ways you can over come when you have no space left on condition.

1 Easy way :

Create a duplicate ui of the existing UI Action and on the duplicate UI action remove all the condition and place only the condition for which there was no space left.

2. Scripted Way: 

Create a script include with all the conditions and call the script include in UI action.

Now the choice is yours... 🙂
