Workaround for Prior Month Default on P&L?

Hi ​@Katrina0826 

Reports like P&L are ARM (Report Definitions) reports. ARM reports are convenient for creating financial reports. However, ARM reports also have the disadvantage that you cannot customize the available parameters to your liking. You can use Report Designer, a powerful tool with much more customization support using formula settings to fulfill your requirements.

Hello ​@Katrina0826 

Did you try with (@StartPeriod, -1) Predefined Parameter?

Thanks

I like ​@YasasWithanage76 ‘s idea, and tried it.

I could not use the suggested text  (@StartPeriod, -1) in Start Period field of Report Definitions.

In the Column Set, Start Period does not accept the suggested text, either. 

Your reports will successfully default to the prior month if you update Period Offsets to -1 on every column of every report.  If any of your reports already contains a value in Period Offset field, you will need to subtract 1 from the existing value.

This is a Work-around, as you asked, but a difficult, confusing, and counter-intuitive work-around, in my opinion, because

1. Potentially, multiple P & L column sets will need to be updated.
2. Users may be confused when running a P & L for any period will result in a report for the previous period, without warning or explanation.

Thank you!
