How to ignore old encumbrance journals from purchasing

Dears,

I am beginning to start the integration between Purchasing and GL

First, I change the status for the organization in Costing information tab then "Transfer to GL" = "No", to stop receiving any old journals and hashing them

Second, The purchasing module is active but no one doing the create account and transfer to GL for receiving, I did it and now old journals created (working fine and no journals created and no transferred )

Third, Encumbrance is enabled but no one doing the transfer to GL for encumbrance journal, I did it but I found old journals created in GL encumbrance journal for these years 2014,2015,2016,2017,2018
