Scap
I was asked to pay for it at a previous carrier but I assumed at the time it was because we were not operating new aircraft.
I needed the data for our flight planning system. I got lucky in the end as the provider of our flight planning software actually had the scap data for the same engine/airframe config from another customer so they just allowed us to use it. Legal or not? who knows?
Possibly give your software provider a call and see if they have it. Failing that you should try you company Boeing rep. Am sure they can help.
Another problem you may be facing is if you are not the actual owner of the aircraft then that might be one reason they are charging. If xyz leasing company owns it then you should give them a call and explain that this data is required and insist that they source it.
Quite strange that you would be charged for it if your company purchased the aircraft new from the factory.
Best of Luck
