Hi,
Sorry to ask for it but where did you get the document? I can’t find it online. Would you mind sharing it?
Do you have BigFix Inventory or ILMT? New BigFix/BFI components will be reported as HCL publisher. How ever they still should be assigned to IBM BigFix product to calculate the RVU metrics.
For the 3rd point, if you have ILMT then Bigfix components can be assigned to ILMT establishment product. If your BigFix is used for other products such as Patch etc then the BigFix Platform Agent should be either bundled or shared with other BigFix product to calculate proper license usage
