Power Apps Maker Portal vs Classic Solution Explorer - Feature Capability Comparison

With the introduction of Power Platform, we can now do table configuration for Dynamics 365/CDS in two places – within the good ol' “Classic” Solution Explorer"(«OrgName».crm.dynamics.com/tools/solution/edit.aspx) and now within the new Power Apps Maker Portal (https://make.powerapps.com).

The Classic solution explorer has always been the place where we customise the system since the old Dynamics CRM days, and all system customisers with Dynamics background uses this up to this day. The Power Apps maker portal is where the Power Apps maker customises the Common Data Service, the model-driven apps and other Power Platform components. Since there are a lot of shared components between Power Apps and Dynamics 365, maker portal has been my preferred way to customise the system, especially with the introduction of the new WYSIWYG model-driven form designer and the new view designer for model-driven apps. I start my customisation from maker portal and only when I hit a roadblock due to the feature gap, that I click on the “Switch to classic” button to open up the Classic solution explorer and continue the task which I cannot do yet / not available yet in the maker portal.

But I still find a lot of the consultants within my circle who are reluctant to use the maker portal because of the feature gaps, and unawareness of the new features that are available in the maker portal. If the system customiser has that knowledge, the system customiser can pick up the right tool for the job – as the saying goes, “a tool is only as good as the hands that wield it”– so picking up the right tool for the right job will save you a lot of time and make your work a lot easier and faster to complete.

There is an official Microsoft documentation of feature capability comparison between Power Automate and classic workflow but I could not find one for the feature-capability comparison between Power Apps maker portal vs Classic solution explorer. So, I decided to start one up by myself and maintain it until there is such documentation available from Microsoft which will help the makers and system customisers to transition to the Power Apps maker portal.

This table summarises the comparison between Power Apps maker portal (referred to as “Modern”) and Classic solution explorer (referred to as “Classic”) capabilities.
The list is categorised into the following 5 different tables based on the nature of the capability.

1. Solution Designer
2. App/Sitemap Designer
3. Table Designer
4. Column Designer
5. Form Designer
6. View Designer

Note: Features which are available in both designers and are redundant/(almost) deprecated features (like "Enable Business Process Flow for Entity", "Phone Express", "Reading pane in Dynamics 365 for Outlook", etc.) are not included in this list.

Table Designer

Capability	Modern	Classic	Comparison	Remarks
Create a table faster	Yes	No	When using the Modern Table Designer to create a table, the table will be provisioned in the background and the UI allows you to continue to make any additional customisations. This allows you to create a table faster in comparison to the Classic table designer which freezes the screen for a few seconds and does not allow you to continue with your work until the table creation is completed. Ref: https://powerapps.microsoft.com/en-us/blog/creating-new-entities-is-faster-than-ever/	New Feature

Set Auditing Settings	Yes	Yes	Not available in the maker portal, only in the solution explorer at this stage.	Feature Parity
Add Table Subcomponents	Yes	Yes	Now, we can add subcomponents within the modern table designer without going out to the table list. In the modern table designer, the subcomponents can only be added by selecting the table within the solution. In order to add subcomponents, open the solution, select one particular table that you want to add subcomponents and the "Add subcomponents" button will appear at the top menu as in the screenshot below. However, it cannot be done from the table subcomponents list view (e.g. columns, forms, views, etc.) as in solution explorer after opening the table.	Feature Parity
Include table metadata for existing table in the solution	No	Yes	In the maker portal, "Include table metadata" checkbox is only available when the table is added into the solution and not available to be selected for the existing table in the solution.	Feature Gap
Select Table Subcomponents	Yes	Yes	Now, the modern table designer can show relevant information when the subcomponents are selected for the existing table. In the modern table designer, only 4 columns, the Display Name, Name, Column Type, and Managed externally are shown in subcomponents selection of any type. This causes some difficulties in choosing: - Relationships because it is harder to identify the type of relationship (1:N, N:1 or N:N), Display Name of the Other Table  - Business Rules because the Scope and State (Activated, Deactivated) is not available - Views because the View Type is not available - Forms because the Form Type is not available and there can be the forms with the same name (x3 Information forms with different types)	Feature Parity
Include columns for Add Existing Table	Yes	Yes	"Search columns" textbox is now working in the column selection for Add Existing Table in the modern table designer.

Instead, the list contains some additional components which are not in the solution explorer such as the Type - Standard/Custom, Required and Searchable.	Different Behaviour
Display Primary and Related Table in Relationship Definition	Yes	Yes	The visual presentation of the relationship is better in the modern table designer to identify which side is Primary (One) table and which one is Related (Many) table, which one is the current table and in which table the lookup column will be created.	Improved Feature
Pre-populate Relationship Name for new Relationship	Yes	Yes	Just as in creating a new lookup column, different table designers pre-populate the relationship name differently when the new relationship is created.

Column Designer

Capability	Modern	Classic	Comparison	Remarks
Create/Update columns, key, and relationships in Batch	Yes	No	Unlike the Classic table designer, the Modern table designer does not immediately create/update the columns. This allows the user to quickly create/update multiple columns without waiting in-between and all changes can be pushed to the server in batch in the end. With the Modern table designer, the data type of the column can be quickly changed by deleting the column and re-creating it with the same name. Modern table designer pros and cons: Pros: Ability to discard all changes by not saving the table Cons: Risk of losing all pending changes if the user forget to save the table Ref: https://docs.microsoft.com/en-us/powerapps/maker/common-data-service/create-edit-field-portal#save-new-field	New Feature

View Designer

Capability	Modern	Classic	Comparison	Remarks
Add columns using the plus button in the canvas	Yes	No	In the modern view designer, the columns can easily be added using the "+ View column" button in the canvas or by selecting columns in the left-hand column drawer. Ref: https://powerapps.microsoft.com/en-us/blog/introducing-the-new-view-designer-for-model-driven-apps/	New Feature
Reorder columns and resize columns using drag-and-drop	Yes	No	With drag-and-drop capabilities in the modern view designer, the columns can easily be reordered and resized to the perfect width. Ref: https://powerapps.microsoft.com/en-us/blog/introducing-the-new-view-designer-for-model-driven-apps/	New Feature
Visualise the view with live preview data	Yes	No	With the live preview in the modern view designer, the makers no longer have to save and publish to determine if the column widths are right. Ref: https://powerapps.microsoft.com/en-us/blog/introducing-the-new-view-designer-for-model-driven-apps/	New Feature
Search and filter in the columns list	Yes	No	The columns list in modern view designer supports incremental search as well as the ability to filter and see only custom columns, making the task of finding and adding columns to the view fast and easy. No more browser search (Ctrl + F) as in classic view designer to find the column in a long list.	New Feature
Save and publish the view in one click	Yes	No	In the modern view designer, save and publish is also a single combined action helping reduce the clicks for one of the most common actions.	New Feature
Undo changes to the view	Yes	No	Changes in the modern view designer are instantly reflected in the view preview and can also be reverted using the Undo button in the command bar.	New Feature
Create a new column	Yes	No	In the modern view designer, a new column can be created as in the modern form designer.	New Feature
Sort by more than 2 columns	Yes	No	The modern view designer allows sorting more than two columns which was not possible previously via the user interface in the classic view designer.	New Feature
Add filters and sorting inline	Yes	No	The modern view designer allows to add filters and sorting inline by clicking on the arrow beside each column.	New Feature
Edit filters using the advanced expression builder	Yes	Yes	For more complex filter, the advanced expression builder can be used to filter on columns which are not in the view. For example, Accounts that do not have any related child Contact rows need to be shown. This can be achieved in Advanced Find with “Does not contain data” filter added in version 9.0. But system view with such filter criteria couldn't be created previously due to the limitation of classic view designer. But in advanced expression builder of the modern view designer, the makers have the ability to add any types of available clauses from the Advanced Find to the system views.	Improved Feature
Configure Custom Controls for the View	No	Yes	Configuring the Custom Controls for the View (e.g. Editable Grid, Calendar View) is not available in the maker portal, only in the solution explorer at this stage.	Feature Gap
Add system columns	Yes	Yes	The maker needs to change the column filter to "All" to add system columns (such as Created By, Created On, Modified By, Modified On, Owner, Status, Status Reason) and those columns are not available in the Default column list of the modern view designer.	Different Behaviour

I will update the list as and when I find more updates to the Power Apps maker portal in the future.

Please leave a comment if you find any missing functionality or any frustrating behaviour with the Power Apps maker portal which is not in the list above and I will include those in the list.
