I am not sure what you said is totally correct. If you are using Cash Manger then you are probably not using Bank Recon but, rather, doing your bank recon in Cash Manager.
When using Cash Manager, a table called CashSumD is maintained whenever cash related transactions are posted. This table keeps track of daily balances. So, if you change a cash related transaction date then this table needs to be rebuilt by running the CA Integrity Check process.
