give me the corresponding statement which should validate in sap datasphere FormatDate(RelativeDate(CurrentDate();-1*DayNumberOfMonth(CurrentDate()));"yyyyMM")
In SAP Datasphere, the expression you've provided uses the function `FormatDate` combined with `RelativeDate` and `DayNumberOfMonth`. To validate your expression, ensure that you're following the correct syntax and conventions used within your specific SAP Datasphere context.
Your expression, as is, appears to be aiming to format the last day of the previous month in the "yyyyMM" format. However, to ensure it validates properly, it’s important to check for proper syntax and compatibility with your environment.
Here is the breakdown for better understanding:
1. **CurrentDate()**: This function returns the current date.
2. **DayNumberOfMonth(CurrentDate())**: This part retrieves the day of the month for the current date.
3. **RelativeDate(CurrentDate(); -1 * DayNumberOfMonth(CurrentDate()))**: This creates a date that subtracts the number of days in the current month from the current date to arrive at the last day of the previous month.
4. **FormatDate(...; "yyyyMM")**: Finally, this formats the resulting date into a "yyyyMM" string format.
Here’s the refined statement to validate in SAP Datasphere:
```plaintext
FormatDate(RelativeDate(CurrentDate(), -DayNumberOfMonth(CurrentDate())), "yyyyMM")
```
Make sure to:
- Remove any spacing issues.
- Check whether the date functions and formatting options are supported as described in your version of SAP Datasphere.
- Validate the overall architecture and use case, ensuring that these functions work as intended in your model.
If you run this code in your SAP Datasphere instance, it should give you the desired output of the previous month in the "yyyyMM" format.
