Credits are the currency of ArcGIS Online, required for services such as performing analytics, storing features in the cloud, and using premium content. While most ArcGIS Online workflows do not require credits, and many credit-consuming activities have a relatively low cost, it’s important for organization administrators to understand how credits work and how to allocate and manage them. The ArcGIS Online help topic of the month provides answers to common questions about credits in ArcGIS Online. 

ArcGIS Instant Apps are the quickest, no-code way, to go from your map to an app. All Instant Apps templates can be found on the searchable Instant Apps home page. But which is the right one for you?

Multifactor authentication (MFA) is a security measure that is highly recommended to protect your accounts and sensitive information. MFA provides increased security by requesting additional verification information when members sign in.

The Analysis button is located on the Settings (light) toolbar and is used to access analysis tools and raster functions in Map Viewer. There are several reasons why you may not have access to analysis in Map Viewer, including licensing, credits, and data requirements.  

Group layers are an important and effective way to organize  map layers. The October ArcGIS Online update added the ability to save group layers as items, making these really important building blocks for reuse and sharing.

In ArcGIS Online October update, we added support to use related table information in Public Notification. Public Notification app allows users to identify a collection of properties and create structured mailing lists of owners and occupants. Think of a scenario where you want to identify a set of properties and notify the owners about an upcoming development project. You have a Parcel layer with all the parcel information except addresses and all the address information for these parcels are stored in a related table. In this scenario, you want to set up the mailing labels in a way that the information will come from the related table instead of the parcel layer itself, here is how you can set up the pop-up to use related records.

1. In your parent layer pop-up, only add related records element and nothing else 

    2. In your related table pop-up, add a text element and configure the address labels 

   3. Save the map and use it to create a Public Notification Instant App.

Key takeaways: 

• It is critical that you use the related records element because a layer can be related to multiple layers/tables and they all could be in the map. The related records element defines the relationship to be used. This allows the app to know exactly which related layer/table should be used in the label. If a layer has multiple related records elements configured, it will use the first one defined in the list.
• Public Notification app will only use the related table pop-up when the feature layer has a pop-up configured with a related records element specified as the first element in the pop-up. In the example below, the layer has 2 elements, a fields list and a related records element. However, the fields list element is first. As a result the app will use the layer's pop-up and the field list to define the label, and ignore the related table's pop-up. So make sure the related records element is the first in order for this to work.

• The app can retrieve multiple related records tied to a single feature.
• Only known limitation is, if a field is added from parent layer to related table, pop-up using arcade field expression will not be resolved. We are planning to fix this in next update.

ArcGIS Online was just updated (October 2023). Learn what's new by reading the following resources.

In ArcGIS Online, you can add and calculate new attribute field values based on existing attribute values in a hosted feature layer you own or administer. The ArcGIS Online help topic of the month for October 2023 explains how to use ArcGIS Arcade and SQL to calculate field values in ArcGIS Online. The topic also provides example syntax for performing common calculations.

Layer pop-ups are an important part of crafting the complete map information experience. Pop-ups can transform an otherwise dull list of attributes into a far more meaningful display of intuitive and engaging information for your audience. Arcade can be thought of as a collection of useful tools that can be applied to craft the very best pop-ups, leveraging functions and logic to perform calculations, geometric operations, format text, access data from other layers, and much more.
