At first;
I would parse the month into a single integer variable
Create integer variable; default value
parseInteger((formatDateTime($Record/CreationDate,'MM')))
Then a create string variable where I would determine the string for ‘Cost’
if
$MonthInteger = 1
then
'Jan’
else
if
…..
And use this variable to set the value in the change object
→ Anyone with better solution regarding the integer to string conversion??
