Warning
Helix documentation is moving from docs.bmc.com to docs.helixops.ai
Key pages will redirect to the new domain on May 26, 2026. However, some legacy documentation links will not be redirected.
In-product help links might not work after migration as we transition and update them within the product.
For any queries, reach out to IX-Support@helixops.ai.
Reserved field ranges
AR System has special ranges of field IDs. Numbers 1-99 are reserved for core fields. Numbers 100-536868911 are reserved for registered fields. The following table lists reserved field ranges that forms and applications use in AR System.
Warning
Important
In the Best Practice Customization mode, a warning is displayed when you create or copy fields in the BMC reserved range on an overlay form. This warning states that creating or copying fields might cause a failure in future application upgrades, if the created field conflicts with a similar field introduced during an upgrade. However, this warning is not displayed when you create or copy fields in the BMC reserved range on a custom form. In the Base Development mode, a warning is displayed when you create fields using the field ranges that are outside the BMC reserved range on a base or overlaid form.
