Introduction 

Some GoGreen and Food Purchase interfaces support advanced Data offset validation logic for Hourly and Daily imports. 

Unlike standard Data offset validation, where PMI checks for data on a single expected day, these interfaces validate data across a configured date range. PMI only requires data to exist for at least one day within the configured range for the interface to be considered successfully updated. 

This logic helps support integrations where data may not be received every day, while still ensuring PMI can identify interfaces with missing or outdated operational data. 

Availability 

This validation logic only applies to: 

    • Hourly interfaces 
    • Daily interfaces 

It does not apply to Monthly interfaces. 

Supported interface types 

30-day range validation 

The following interface types use a 30-day validation range: 

    • GoGreen_GreenSleep 
    • GuestFeedbackScore 
    • GuestFeedbackCount 
    • GoGreen_Waste 
    • GoGreen_Chemical 

If PMI finds data for at least one day within the configured 30-day range, the interface status is displayed as Updated in PMI. 

If no data is found within the range, the interface status is displayed as Not updated in PMI due to missing data. 

7-day range validation 

The following interface types use a 7-day validation range: 

    • FoodPurchase 
    • GoGreen_Linen 

If PMI finds data for at least one day within the configured 7-day range, the interface status is displayed as Updated in PMI. 

If no data is found within the range, the interface status is displayed as Not updated in PMI due to missing data. 

How the range is calculated 

The Data offset defines the last date in the validation range. 

PMI then calculates the configured range backwards from that date. 

Example: GoGreen_Linen interface 

Configuration: 

    • Interface type: GoGreen_Linen 
    • Validation range: 7 days 
    • Data offset: -30 

Scenario: 

    • Today is 9 June 
    • Data offset -30 means PMI expects the last day of the range to be 10 May 

Because GoGreen_Linen uses a 7-day range, PMI checks for data between: 

    • 4 May 
    • 10 May 

If PMI finds data for at least one day within this period, the interface status is displayed as Updated in PMI. 

If no data exists within this range, the interface status is displayed as Not updated in PMI. 

Operational impact 

This validation logic helps reduce false warnings for interfaces where data may: 

    • arrive irregularly 
    • only be updated periodically 
    • not contain data for every calendar day 

Instead of validating a single expected day, PMI validates whether sufficient operational data exists within the configured historical range.
