Hi Madhu,
There is no workaround for this functionality.
Once it is active, you will always have PO with service bundling and this can't be deactivated again.
So if you decide to have this functionality, please activate it then.
For the new query about status, I didn't see any problem about it. This status should be inactive once follow-on doumet such as PO is created.
best regards,
Ivy
