At the moment i'm trying to create a new variable which contains an existing variable.
The existing variable will generate a period of time , for example: 201901, 201902.
I want to check on the last 2 digits from the result of the existing variable, after I want to receive another period which I can hardcode. Result might be 201812 or 201912. So the current of previous year with '12 or 06' behind it.
