Add a characteristic in the extractor

Hello,

I need to add a new characteristic in the delta extractor 2LIS_11_VAHDR.

I don't want to reload the data (initialization) in the infoprovider and I don't want to break the "delta" loading.

Is it possible to add the characteristic in the extractor then ? Are there special things to check before adding the fiels (like to delete LBWQ or RSA7) ?

I just want the new characteristic to be filled in the future with the future orders.

Can someone help me ?

Thank you for your answers.
