Active connections

keivan — Mon, 28 Nov 2022 16:31:06 GMT

Hi all,

I would like to calculate the number of active connections.
My dataset is compose in this way:

Calendar Table (Date, Year, Month, etc.)
Connections Table (connection_id, etc.)
Consents Table (consent_id, connection_id, valid_until, etc.)

When a client create a connection (connection_id 1111) he provide a consent (consent_id 2222) this consent has an expiration date (for example 25/08/2022). When this consent expire the client can renew the consent for its connection.
If the client renew the consent, a new consent_id will be generate (consent_id 3333) but the connection_id would NOT change (connection_id 1111).

In order to calculate if an active connection is active, I have to check if the valid_until of its newest consent is < TODAY or not.
Consent_id are integer and are progressive numbers.

Sorry to bother you, but I don't know how to make BI perform this calculation.
Thanks,

Hi keivan ,

If you want to get active connection id, you can create a measure to filter your id list.

Measure = VAR _LASTDATE = CALCULATE ( MAX ( Consents[valid_until] ), FILTER ( Consents, Consents[connection_id] = MAX ( Connections[connection_id] ) ) ) RETURN IF ( _LASTDATE >= TODAY (), 1, 0 )

Add this measure into visual level filter and set it to show items when value =1.

Result is as below.

According to your statement, I think your requirement is based on your data model. Please share a sample file with me and show me a screenshot with the result you want.

Thanks Rico,

It almost works.
I paste below the formula. If I remove the Return to the formula calculates correctly among the various consent the last one and report the expiration date. ( I share the screenshot).

However keeping

RETURN

IF ( _LASTDATE >= TODAY (), 1, 0 )

It reurns always 0

Active Connections =

VAR _LASTDATE =

CALCULATE (

MAX (consents[consent_valid_until] ),

FILTER (

Consents,

consents[connection_business_id] = MAX ( Connections[connection_business_id] )

)

RETURN

IF ( _LASTDATE >= TODAY (), 1, 0 )

Correct the calculation of expiration date
