Description - In CJA, there's a function called Split to split a value from a field into a new derived field, and the output can be an array. Would like to have a function which is like a reverse-split i.e. to take a array field and join them back with a delimiter to become a string field.
Why is this feature important to you - To support reporting of a combinations of items as a bundle of items.
How would you like the feature to work - A new drived field function or enhance the current Concatenate function to take an array field as input with a delimiter.
Current Behaviour - Currently there's no such feature. Details please refer to the below link,
