Power BI - averages and calculations for forecasting (accounts)
Hi,
I'm working on a problem with Accounts Receivable Data. I have created a table in P.BI one showing Client Account No, Client name, Count of paid Invoice number, Average Days to pay, Number of outstanding invoices, Total Outstaning and Average Amount of Days Overdue for payment. The data is coming from 4 data sets with relationships created between them.
i have been asked to work out a way to show if an invoice is likley to be paid in the current month based on historical payments (my average days to pay column)
IM STUCK.
can you calculate on averages? ive tried but all just get ERROR.
Can you use PBI to forecast in this way? (IF days overdue is greater than average days to payment in the next 10 days return a'YES')???
Any help much appreciated.
Thanks
H.

RE: Power BI - averages and calculations for forecasting
Hi Helen,
Thank you for the forum question.
Yes you can calculate average but the DAX measures is all based on your relationships. I need to know more about your data model to be able to help you.
Do you have Due date and Paid date in separate tables? Are the tables related by invoice invoice numbers?
The Average function can only calculate the average of a single column. You may need and AverageX function to do it.
Kind regards

RE: Power BI - averages and calculations for forecasting
Hi Jens,
the data is coming from 4 data sets and the are linked by relationships.
1) Credit Control Chased
2) Invoices Outstanding
3) Cash Allocated - Paid invoices data
4) Clients
1 and 2 have a both direction relationship on the invoice number.
2 and 4 have a both direction relationship on the Client Number.
1 and 3 have a both direction relationship on Invoice Number.
Due date in in invoices table and Paid date is in the credit control table.
I have used...
(AVERAGEX('Credit Control',[DAYS_OVERDUE])-AVERAGEX(OA_CASH_ALLOCATED_VW,[Days to Payment]))
to get the difference between the 2 averages. I now need to return a YES if there is 10 days either side of 0 (i.e. -10 through 10)
Any ideas?
thanks

RE: Power BI - averages and calculations for forecasting
sorry, slight change to above
I have used...
(AVERAGEX('Credit Control',[DAYS_OVERDUE])-AVERAGEX(OA_CASH_ALLOCATED_VW,[Days to Payment]))
to get the difference between the 2 averages.
I now need to return a YES if there is a possibility it will be paid in current month i.e. there are more or equal days left in month to average days to payment?
I have a full date file in the model.
Hope that makes some sense?
Thanks

RE: Power BI - averages and calculations for forecasting
Hi Helen,
The If should look like this.
If(AVERAGEX('Credit Control',[DAYS_OVERDUE])-AVERAGEX(OA_CASH_ALLOCATED_VW,[Days to Payment])> DATEDIFF(today(),EOMONTH(today(),0),DAY),"No","Yes")
Let me know if it makes sense. You can get an circular error if the calculation is in the "wrong" table. Please let me know if it is not working.

RE: Power BI - averages and calculations for forecasting
Hi Jens,
Happy New Year.
sorry I am just re-visiting this as other item took priority.
I have used
Payment likely =
IF (
AVERAGEX ( 'OA_CREDIT_CONTROL_NOTES_VW', [DAYS_OVERDUE] )
- AVERAGEX ( OA_CASH_ALLOCATED_VW, [Days to Payment] )
> DATEDIFF ( TODAY (), EOMONTH ( TODAY (), 0 ), DAY ),
"No",
"Yes"
)
and I get NO for every line. I cant work out what's gone wrong, any ideas?
Thanks

RE: Power BI - averages and calculations for forecasting
Hi Helen,
Happy New Year to you too.
I will need to see your data model. Is it possible for you to send me the file?
The AverageX function probably only filter the number of days for each record in the table you have your If.
If the two tables are related and you have the If in the 'OA_CREDIT_CONTROL_NOTES_VW' table try:
IF (
AVERAGEX ( 'OA_CREDIT_CONTROL_NOTES_VW', [DAYS_OVERDUE] )
- AVERAGEX ( RelatedTable(OA_CASH_ALLOCATED_VW), [Days to Payment] )
> DATEDIFF ( TODAY (), EOMONTH ( TODAY (), 0 ), DAY ),
"No",
"Yes"
)
If you can send me the file please send it to:
