Introduction

Dimensions are things that you can book, such as a room, a person or a product. Out of the box, Booker25 provides dimensions for Resources, Staff, Groups and Contacts. The first 3 are custom objects, while the last one is the Salesforce standard Contact object. This article explains what you can do with dimensions, and how you can create your own.

By using dimensions, you can:

• make sure that bookable items are Included in the Booker25 conflict checking logic. More information about conflict detection: Conflict Checking
• make sure that you only add available items to your reservations by using intelligent lookups (more on this below)
• create calendars for bookable items that will show their reservations. This means you could show a calendar on a contact record page, on which you show in turn see that contact’s reservations. More information about calendars: Calendar Differences
  

Practical example

Imagine you have a fleet of cars and drivers. Your cars are stored in a custom Car object (Car__c), while your drivers are stored in the standard Contact object. You now want to track both your cars and drivers availability. As we mentioned earlier, Booker25 provides a Contact dimension, so you're all set as far as your drivers go. But how do you track your cars? And how do you make sure it does not cost you double work to track which car is assigned to which driver at each moment in time?

Simple! You create a Cars Dimension in Booker25. That way, when you create a reservation from either the driver or the car calendar, and link the other to it as well, Booker25 will draw that reservation on both calendar and keep both in sync at all times!

Technical overview

Dimensions are a powerful way of letting Booker25 know about records on any standard or custom object that are related to Reservations in, either through a lookup or via a junction object:

The Reservation object has a lookup to the other object.

Introduction

Dimensions are things that you can book, such as a room, a person or a product. Out of the box, GoMeddo provides dimensions for Resources, Staff, Groups and Contacts. The first 3 are custom objects, while the last one is the Salesforce standard Contact object. This article explains what you can do with dimensions, and how you can create your own.

By using dimensions, you can:

• make sure that bookable items are Included in the GoMeddo conflict checking logic. More information about conflict detection: Conflict Checking

• make sure that you only add available items to your reservations by using intelligent lookups (more on this below in the Define Dimension Field section)

• create calendars for bookable items that will show their reservations. This means you can show a calendar on a contact record page for example, on which you show in turn that contact’s reservations. More information about calendars: Calendar Differences

Practical example

Imagine you have a fleet of cars and drivers. Your cars are stored in a custom Car object (Car__c), while your drivers are stored in the standard Contact object. You now want to track both your cars and drivers availability. As we mentioned earlier, GoMeddo provides a Contact dimension, so you're all set as far as your drivers go. But how do you track your cars? And how do you make sure it does not cost you double work to track which car is assigned to which driver at each moment in time?

The easy option

GoMeddo also includes a Calendar Wizard, which allows you to select any custom or standard object and creates calendar records for that dimension. See the main article here: Calendar Wizard

Technical overview

Dimensions are a powerful way of letting GoMeddo know about records on any standard or custom object that are related to Reservations in, either through a lookup or via a junction object:

Dimensions & Dimension Fields

Now let's have a look at how you configure this

Define Dimensions

First, we start by telling GoMeddo about the object that holds the bookable items. We assume the object you want to use already exists. Else, start by creating a custom object.

1. Go to the GoMeddo app

2. Click on the Dimensions tab

3. Click New

4. Fill in the following fields

The fields below are only necessary if you have Conflict Rules enabled and want to use Resource Grouping :

The fields below are only necessary if you do not have Conflict Rules enabled:

Define Dimension Fields

Next, we configure a way to link bookable items to reservations

1. On the Reservation object, create a lookup to the object that holds the bookable items. In our example, this is a lookup to the Car__c object. (We won't go into too much detail on this one, as it's basic Salesforce admin knowledge)

2. Make sure the field is part of the correct field set you will be using

3. Go back to the Dimension you created in the previous section

4. Go to the Related tab

5. Click New in the Dimension Fields section

6. The only field you currently need to fill in is Dimension Field Name, in which you fill in the API Name of the field you created in step 1 of this section

7. Click Save

The following tables goes into more detail regarding the function of the other fields:

1: Can also be a cross-object reference or a checkbox formula on Reservation. However the latter will not be set yet when working from the Reservation Form UI.
2: Required when Enforce Capacity Check is enabled.
3: Can also be a number formula, and can also be a cross-object reference.

Define Dimension Junctions

Dimensions Junctions are a way to let Booker25 know which junctions between a dimension and a reservation are important.

Create a calendar

Create calendar config

Set up Calendars & Views

Create the actual calendar

Add a Calendar to a Lightning App Page

Dimension Junctions

Dimensions Junctions are a way to let GoMeddo know which junctions between a Dimension and a Reservation are important. An example of this would be a

...

Contact list, where you link multiple

...

Contacts to a

...

Reservation.

Using dimension junctions you can:

• Make this list visible on the reservation form

• Make the

...

• Reservation visible on the

...

• dimension calendar for each

...

• dimension record in the list

...

• Make

...

• GoMeddo detect and prevent double bookings for these contacts

...

...

There is an edge case where you can get an error like this: SObject row was retrieved via SOQL without querying the requested field: B25__Reservation__c.<junctions>__r (where <junctions> is your relationship name).

...

Define Dimension Junctions

Now let's see how we can configure a Dimension Junction

1. Create a junction object with two lookups (or Master-Details): one to Reservation and one to the object that holds the bookable items.That object is Car__c in our example. (We won't go into too much detail on this one, as it's basic Salesforce admin knowledge)

2. Go back to the Dimension you created in the previous section

3. Go to the Related tab

4. Click New in the Dimension Junction section

5. Fill in the fields from the following table:

...

...

...

...

...

Defines the behavior when Reservations are saved outside of the available times for the related dimension record.

• None - Allow the Reservation to be saved
• Soft - Allow the Reservation to be saved, but show a warning to the user and enter a Conflict record in the database
• Hard - Don't allow the Reservation to be saved, and show an error message to the user

For more information, see this article about Conflict Checking, and this article about Availabilities

...

Defines the behavior when double bookings are detected for Reservations in this Dimension.

• None - Allow the Reservation to be saved
• Soft - Allow the Reservation to be saved, but show a warning to the user and enter a Conflict record in the database
• Hard - Don't allow the Reservation to be saved, and show an error message to the user

For more information, see this article about Conflict Checking.

...

1: Can also be a cross-object reference or a checkbox formula on Reservation. However the latter will not be set yet when working from the Reservation Form UI.

Create trigger hook

For every Dimension Junction you create, make sure you also create a Trigger for its object, which calls the following method: B25.DimensionJunctionTriggerHook.execute()

This makes Booker25 check permissions on the object. Make sure to replace <Dimension_Junction_API_Name> with the actual API name of your object, and <Trigger_Name> with a name that makes sense to you.

trigger <Trigger_Name> on <Dimension_Junction_API_Name> (before insert, before update, before delete, after insert, after update, after delete, after undelete) {
	B25.DimensionJunctionTriggerHook.execute();
}

Displaying Dimension Junctions on the Reservation Form

After you have configured Dimension Junctions (see Configuring Dimensions & Dimension Junctions) you might want display this Related List on the Reservation Form and allow users to add new records. To do this, you have to create a Dimension Junction Display Setting record on each Reservation Type you want to display this related list for. You can find this by going to the Reservation Type record and then to the Related tab.

The Dimension Junction Display Setting has some additional fields that allow you to control certain aspects of this related list.

Create trigger hook

For every Dimension Junction you create, make sure you also create a Trigger for its object, which calls the following method: B25.DimensionJunctionTriggerHook.execute()

This makes GoMeddo check permissions on the object. Make sure to replace <Dimension_Junction_API_Name> with the actual API name of your object, and <Trigger_Name> with a name that makes sense to you.

trigger <Trigger_Name> on <Dimension_Junction_API_Name> (before insert, before update, before delete, after insert, after update, after delete, after undelete) {
	B25.DimensionJunctionTriggerHook.execute();
}

Please be aware that a test class should be create which allows you to test this trigger. You can create a simple test class that inserts a reservation, a related object record and the dimension junction record. Here is an example that you can tweak to facilitate your use case

@IsTest
private class Test_B25_Reservation {

    @isTest private static void testDimensionJunctions() {
        B25__Reservation__c reservation = new B25__Reservation__c();
        reservation.B25__Start__c = DateTime.now();
        reservation.B25__End__c = DateTime.now().addHours(1);
        Database.insert(reservation);

        <YOUROBJECT>__c yourobject = new <YOUROBJECT>__c(); //replace this with the name of your object
        yourobject.Name ='a'; // if this is field is an auto number you dont need this.
        Database.insert(yourobject);

        Reservation_<YOUROBJECT>__c resYourobject = new Reservation_<YOUROBJECT>__c(); //replace Reservation_<YOUROBJECT>__c with the name of your dimension junction object
        resYourobject.Reservation__c = reservation.Id;
        resYourobject.<YOUROBJECT>__c = yourobject.Id; //replace this with the name of the lookup on the dimension junction
        Database.insert(resYourobject);

        System.assertEquals(1, [SELECT Id FROM B25__Reservation__c].size());
    }  
}

Display your Dimension Junctions on the Reservation Form

Additional fields information

The table below goes into more detail about each field on the Dimension Junction record.

Note: this setting is only supported on Lightning calendars.

If you get an error when saving a reservation with junction records, double check if you have implemented the trigger hook described in the final section of Configuring Dimensions & Dimension Junctions.

...

1: Can also be a cross-object reference or a checkbox formula on Reservation. However the latter will not be set yet when working from the Reservation Form UI.

General Performance Considerations

For performance reasons, it is good practice to only have the minimum number of Dimensions

, especially ones that are configured for conflict checking.
