Hi, 

Err: This attribute cannot be removed because it is currently used in other settings (Product/Part Synchronization rule or Maturity Graph transition rule or POWER'BY xCAD), Please remove those rules before proceeding.

When I try to delete an attribute I created with Attribute Management, I get the attached error. I removed the rule with the relevant attribute in Maturity Graph. In the same way, I canceled the attribute mapping with Catia V5 from CAD Collaboration(POWER'BY xCAD). After all these operations, I did “Update Index Model” and “Reload Cache” from the “Configuration Deployment” section, but I did not understand the “Product / Part Synchronization rule” mentioned in the warning. Where is this rule, if any? Otherwise how can I get rid of this error. I must delete the related attribute. Thank you in advance for your help.
