SCCM Not Recognizing Collection Variables? Here’s How to Fix It
Introduction
Hey there, readers! If you’re facing the pesky issue of SCCM not recognizing collection variables, you’re not alone. This article will embark on a deep dive into this problem, exploring its causes and providing foolproof solutions to get your collection variables up and running in no time. So, grab a cup of coffee or tea, sit back, and let’s dive right in!
Understanding Collection Variables in SCCM
Collection variables are the backbone of SCCM’s powerful device and user targeting capabilities. They allow you to create dynamic collections that automatically adjust their membership based on specified criteria. However, when SCCM fails to recognize these variables, it can lead to inaccurate collections and ineffective deployments.
Common Causes of SCCM Not Recognizing Collection Variables
1. Incorrect Variable Syntax
Double-check the syntax of your collection variables. They must follow a specific format, including the correct variable name, operator, and value. Any deviations from the expected format can cause SCCM to ignore the variable altogether.
2. Missing or Invalid Variable Values
Ensure that the values you are assigning to your collection variables are valid and exist in the system. Non-existent values or values that violate data type constraints will result in the variable being ignored.
3. Incorrect Collection Scope
Verify that the scope of your collection variable matches the scope of your collection. For example, if you are trying to use a user variable in a device collection, SCCM will not recognize it.
4. Collection Evaluation Issues
Sometimes, SCCM may not be evaluating collections as frequently as expected, causing a delay in recognizing updated collection variables. Adjust the collection evaluation schedule to ensure timely variable recognition.
5. Corrupt Database
In rare cases, a corrupt SCCM database can lead to issues with collection variable recognition. Consider running database integrity checks and, if necessary, performing a database repair.
Troubleshooting and Solutions
1. Verify Variable Syntax and Values
Thoroughly review the syntax and values of your collection variables. Use the SCCM documentation or online resources to ensure they meet the required format and constraints.
2. Check Collection Scope and Evaluation
Confirm that the scope of your collection variable corresponds to the type of collection you are creating. Adjust the collection evaluation schedule to ensure regular updates.
3. Reset Collection Variables
If the previous steps don’t resolve the issue, try resetting the collection variables. This will remove any existing values and allow SCCM to re-evaluate and recognize the variables.
4. Clear SCCM Cache
Clear the SCCM cache to remove any temporary data that may be interfering with variable recognition. This can be done by restarting the SMS Executive service.
5. Rebuild Collection
As a last resort, consider rebuilding the affected collection. This will create a fresh collection, eliminating any potential issues with variable recognition.
Collection Variable Reference Table
| Variable Type | Variable Name | Description |
|---|---|---|
| Device | ResourceID | Unique identifier for each device |
| User | UserID | Unique identifier for each user |
| Device | OperatingSystem | Operating system name and version |
| User | Department | User’s department |
| Device | BIOSVersion | BIOS version |
| User | Language | User’s preferred language |
Conclusion
There you have it, readers! This comprehensive guide has hopefully shed light on the issue of SCCM not recognizing collection variables. By understanding the root causes and following the troubleshooting steps outlined above, you should be able to resolve this issue and create dynamic, accurate collections that meet your organizational needs.

FAQ about SCCM Not Recognizing Collection Variables
1. Why is SCCM not recognizing my collection variables?
- Ensure that the collection variables are properly defined and deployed to the collection. Check the collection properties to verify the variables.
2. How can I troubleshoot collection variable issues?
- Check the Collection Evaluation Viewer (CEV) in the SCCM console to see if the variables are being evaluated correctly. If not, adjust the variable or collection evaluation settings.
3. Why is a collection variable not appearing in the dropdown menu?
- Make sure the variable is a member of a variable group that is assigned to the collection. Also, check if the variable type matches the required type in the dropdown menu.
4. How can I determine if a collection variable is being used?
- Check the "References" tab of the variable properties in the SCCM console. It displays all the collections and reports that use the variable.
5. Why am I getting an error when using a collection variable in a query?
- Verify that the syntax of the query is correct. Ensure that the variable name and its data type are used appropriately.
6. How do I update the values of collection variables?
- Edit the collection properties and navigate to the "Variables" tab. Modify the values as needed and save the changes.
7. What is the difference between a collection variable and a global variable?
- Collection variables are associated with specific collections and are only evaluated within those collections. Global variables are available across all collections and are evaluated globally.
8. Can I use collection variables in reports?
- Yes, collection variables can be used in reports to filter or display data based on the values of the variables.
9. How do I create a new collection variable?
- In the SCCM console, navigate to "Assets and Compliance" > "Collections" > "Variables" and select "Create Collection Variable" to define and create a new variable.
10. Why is a collection variable showing an empty value?
- Check if the variable is correctly deployed to the collection. Ensure that the devices in the collection have the latest policy settings applied and have reported their data to the SCCM server.
