As a Member User, you need to be aware of the many possibilities that Crystal offers as well as of some limitations that you might encounter.
A deep knowledge of Crystal allows you to make the most of the experience!
Let's see an overview of the limitations in the Advisor's capabilities for Crystal Web, Mobile, and Teams, broken down by Area and Feature, and summarized.
You will also be redirected to the specific Feature page to find out more details!
Stay Tuned!
We are constantly working to improve our product: check out the section of this documentation to learn about most recent fixes and enhancements!
If a Filter has single alphanumeric characters as values, the detection in conversation of such values is not guaranteed; however these values are supported if filtering the Topic via the capability in the Topic Card instead
Please find out more details in the !
If the requested Entities are not present in at least one Configured Topic, Crystal cannot generate new Topics
When you ask for Entities coming from different Tables, you can involve up to of a maximum of 40 Tables from the chosen Data Source - as this is the current limit for Tables configuration in Crystal
If the requested Entities are spread across multiple Data Sources, they cannot be used to generate a new Topic
When the Entities used for Topic generation are Custom Entities, bear the following limitations in mind:
if a Custom Entity is defined by Columns from Table A, you can request Virtual Topics with Entities different from A only if there are Configured Topics that have the necessary joins
if the Custom Entity is defined by Columns from both tables A and B, you can request Virtual Topics with Entities from both A and B
Topics of type Description or Comparison - Single column pos. neg. cannot be auto-generated
When asking for a Topic of type List, the auto-generated Table Visualization will contain as many Columns as the Entities specified in the question: this means that, if only one Entity is specified, the table will have only one Column and, if you need more Columns, you must specify all the Entities
for example: "Show me a list of customer IDs" and "Show me a list of customer IDs and relative names and ages"
When asking for a Topic of type Ranking, you need to specify the Entity by which you want to order by
for example: "Show me the ranking of sales agents by closed contracts"
Auto-generated Topics won’t be involved in other Crystal capabilities related to Topics, which will be available for Configured Topics only:
, for both Anomaly Detection and Threshold Monitoring (but you can still set an Anomaly Detection via Topic Card)
At the moment, the Objective Inference capability is only available for two Objectives: Composition and Highlight
For all the other cases, you still need to specify the desired Objective in order to obtain the corresponding Visualization
When the Objective is not specified, Crystal will assume that you are asking for a Composition: therefore, a breakdown will be returned by default (if the underlying data allow it)
Filter and Topic Suggestions are based on User permissions
Sometimes it is possibile that the selected Topics contain no data
Suggestions don't change if you delete a word
For Crystal Mobile, the suggestion of Filter Values is limited to a maximum number of values to be shown, regardless of the total number of Filter Values
Autocomplete only considers Configured Topics
Suggestion is limited to a single word at a time
Crystal cannot recognize untrained word sequences
Predictions don't consider User permissions
Autocomplete only considers Configured Topics
The display of Suggestions depends on the presence of a Topic open in Advisor
The display of Suggestions needs a minimum number of Configured Topics
If the minimum needed conditions are not met, it is possibile that Suggestions are random
Suggestions are based only on Configured Topics
This section collects only Configured Topics
Right now, only available for the Top Contributor, Average and Variability and Extreme Values Insights
Dependency on a extended Data Model
Can’t be performed if a Topic only has categorical columns
Can’t be performed if a Topic has at least one Custom Column
If you don't have the permissions for certain underlying data, you will receive a partial analysis with that data hidden
There may be a constraint regarding the number of rows the Feature can handle, though it is estimated to be around hundreds of thousands, chosen from the most recent rows in the considered Data Model of the analyzed insight
Insight Analysis is only available on Configured Topics
Maximum 20 Alerts can be set in total, across Alert type
At the moment, it's not possible to edit Alerts once set
For Auto-generated Topics, Alerts can be set via the Topic Card only, not in conversation
Maximum 10 Anomaly Detection Alerts can be set in total
Anomaly Detections can be requested on one Topic at a time only
Be careful on modifying or deleting a Topic where an Anomaly Detection is active
Auto-generated Topic don't support the capability of setting an Anomaly Detection via conversation (use the Topic Card instead)
Can be activated by Conversation and not via Topic Card
Threshold Monitoring Alert is counted as an Anomaly Detection
Threshold Monitoring can be requested on one Topic at a time only
Be careful on modifying or deleting a Topic where an Threshold Monitoring is active
Auto-generated Topic don't support the capability of setting a Threshold Monitoring via conversation (use the Topic Card instead)
Can be activated via Topic Card and not by Conversation
Maximum 10 Topic Scheduling Alerts can be set in total
Topic Scheduling can be requested on one Topic at a time only
Be careful on modifying or deleting a Topic where an Topic Scheduling is active
Available only for Overtime Single Line Topics
Each Topic must meet some conditions of minimal data points presence
In monthly or daily Topics, the statistical model omits the initial and final data points
You can create up to 20 Data Stories
You can save up to 20 Topics in a Data Story
Dynamic Time Filters with the following patterns don't update properly when saved in a Data Story:
Fixed Start Date + Open End Date:
"From [month] to today"
"From [month] to yesterday"
Specific Open Date Ranges:
"From yesterday to today"
"Until today"
"From yesterday"
The actual number of language choices you have (up until 5) depends on your Project's specific configuration
