Discovery models for software is not createdIssue Discovery models for software are not created or not mappedFacts OOB, When a software record is added to the cmdb_sam_sw_install table, the discovery model is created or linked by the business rule "Create a Software Normalization." This rule considers the software record's primary key.The primary key is the mandatory attribute for the software installations and software usage.The primary key is created in two ways: either by the discovery source or by a business rule "Build Primary Key" which runs before "Create a Software Normalization". This script takes into consideration the value of property "com.snc.samp.exclude_device_flag" which is set to "u_exclude_from_sam". This value is set on the corresponding CI record the software is on. Build Primary Key: https://<instance>.service-now.com/nav_to.do?uri=sys_script.do?sys_id=efd6bb4d37101000deeabfc8bcbe5d44 Create a Software Normalization: https://<instance>.service-now.com/nav_to.do?uri=sys_script.do?sys_id=9ec2b34d37101000deeabfc8bcbe5d43 ReleaseAll releasesCause Go to the system property com.snc.samp.exclude_device_flag and verify if this property is available or not; if this property is available, verify if there is a value to the property. https://<instance>.service-now.com/nav_to.do?uri=sys_properties.do?sys_id=79e091db93b22300d40d14f1b47ffb51 While investigating, it has been observed the above property has a value "exclude_sam". So, any software installation record with this value will be excluded When this value, "exclude_sam," is true, no primary key is created, and "Create a Software Normalization" does not run. As a result, the discovery model is not associated. Resolution The field "exclude_sam" is a custom field. the purpose of this field shpuld be verified, source of update and make necessary changes in the property com.snc.samp.exclude_device_flag.The system property "com.snc.samp.exclude_device_flag" should be OOB and an empty value. Then, the Discovery models should be created for the Software.
