I would create a transaction that convert input number (transactioniid) in other base and returns a string.
For example convert transactionid in hexadecimal base.
And I want that transaction works with every possible transactioid value.
Tha algorithm is very easy:
- char = transactionid%16 converted in char
- transactionid = floor(transactionid / 16)
- repeat until transactionid is not zero
The problem is when transactionid is big and operation generates exception
...the best should be to do it without custom action 
Do you have solutions?
Thank you Rohit
Best regards
