Overview
Conflict Rules allow you to implement your business rules for reservations, by allowing you restrict your reservations based on rules.
You can create easy rules and more complex rules, using below described operators and functions. You can use fields on the reservation and fields of the related dimension record if you link your rule to a dimension.
...
By combining operators, functions, and variables, you can create simple or advanced rules to handle conflicts based on specific criteria, such as resource availability, overlapping reservations, and more.
Getting started
As it’s in beta, you first need to install our latest version 5.6 or later Install the latest version
Navigate to GoMeddo settings, and enable the setting to enable this new way of conflict checking
...
After doing so, all conflict checking configured on the dimension itself, are disabled and only the rules will be used from now on.
Creating and editing rules
Go to the "Booking Restriction Rule" tab and click on "New Rule” or select an existing rule from the list.

| Note |

Important is that when the result is true, the reservation will be blocked. This is why we call the rules “Conflict Rules”. |

Operators
We will support the following logical operators:
Operation | Description |
|---|---|
== | Checks if two values are equal. Returns true if they are, false otherwise. |
!= | Checks if two values are not equal. Returns true if they are not, false otherwise. |
> | Checks if the left value is greater than the right value. Returns true if it is, false otherwise. |
>= | Checks if the left value is greater than or equal to the right value. Returns true if it is, false otherwise. |
< | Checks if the left value is less than the right value. Returns true if it is, false otherwise. |
<= | Checks if the left value is less than or equal to the right value. Returns true if it is, false otherwise. |
CONTAINS | Checks if a text value contains a specified substring. Returns true if it does, false otherwise. |
LIKE | Performs a pattern matching comparison between a text value and a specified pattern. Returns true if the pattern matches, false otherwise. |
NOT | Negates the Boolean value of an expression. Returns true if the expression is false, false if it is true. |
ISBLANK | Checks if a field or expression is blank (empty) or null. Returns true if it is blank, false otherwise. |
Functions
Rules serve different functions, with some of them returning numerical values that you can use in your formula.
...
COUNT(FILTER(records AS record, record.number_field__c > 5)) > 0-> returns TRUE if at least one record has a value higher than 5
Rule linked to dimension
When you link your rule to a dimension, two special variables will become available for use in the formula.
overlapping_reservations
overlapping reservations with the reservation being checkedCOUNT(overlappingReservations) > 0
This rule would make sure that no overlapping reservation are allowedmatchingAvailablilities
Allowing you to use the availability or unavailability of the related dimension in your formula.COUNT(matchingAvailabilities) == 0
Reservation not allowed when there is no availability or if there are unavailabilities.
Use custom permission in a rule
You can also reference and check the permissions of the running user in your rule.
By adding: $Permission.Custom_Permission_NameCOUNT(overlapping_reservations) > 0 and $Permission.B25__ALLOW_DOUBLE_BOOKING == false
Examples rules:

Basic rules
Reservation not allowed when title matches invalid.
...
COUNT(matchingAvailabilities) == 0
More advanced rules
Reservation not allowed when overlapping with other reservations, not taking into account reservation with status “Canceled” AND status “Temporary”
...
COUNT(overlapping_reservations) > 0 and $Permission.B25__ALLOW_DOUBLE_BOOKING == false
Not supported in this beta:
Overlapping reservation containing reservations from other resources.
