1st day of previous month
My name is Neuza Sous, and I'm working with Business Object since last months so I need your help so solve a little problem.
I had use the following formula to give me the 'Last day of previous month', but now the formula stop worked because when it calculates the month it takes one the the current month, but in case of January this doesn't work because is the month 1.
I need to current the formula or update it, and I thought to do it we a 'If' but I'm not sure about how to do it.
Can you please help me?
Thank you in advance.
