Our purchases clearing has gone awry.  We lost our purchase agent in the middle of Covid and now that we are consistently using PO again correctly, our PO clearing is way off.  We have a handle on our current open PO's and back orders, but we are way off in Purchases clearing vs. GL. Instead of going back 4 years is there a process or JE that can be done/made to correct this without negatively affecting the balance sheet? 

PLEASE HELP!
