Hi,
In that scenario you need to setup something like a Schedule job or some rule based on your Integrations to remove those software from Software Installation table and Reconciliation running next time would pick it up from there.
We had the same issue while doing an in house Integration with Puppet tool and we wrote our own script to remove the software installation record based on some criteria.
There is no other way rather than building your own removal script and make sure if your Integration or Discovered data(Table in which data is coming from some other tool is in different scope than Global) table is in some other scope than removal from Software Installation table won't happen as "Delete" access on Software Installation table is not there OOB.
In that case you need to go to the Table View of Software Installation table and mark the checkbox "Can Delete" as True as shown below. We faced this issue while doing one of the integrations related to SAM.
The above image is just an example of one of the table.Seacrh for you SAM Table and mark the Can Dleete Checkbox as true.
Hope this helps. Please mark the answer as correct/helpful based on impact.
Regards,
Shloke
