I was trying to look for some GL IV balances that did not match the IV HITB balances when I first looked for any records in the GL20000 table that did not exist in the SEE30303 table. I found none. However, when I looked in the SEE30303 table for records that did not exist in the GL20000 table I found thousands. So obviously it is common for records to be written to the SEE30303 table but no corresponding records get written to the GL20000 table. Under what circumstances does this occur?
