You are correct. It works for me but only after delta init. In 2lis_11_vakon you cannot trace changes before extractor initialization. Set up table gives only current state.
I need something, which gives me history of changes before 2lis_11_vakon init.
I have been using SIS table for that but do not work always right (ie. when we change currency)
Ie. New value is 150 USD old value is 100 EUR. The delta is counted as 50 USD.
