Bank Reconciliation

I am trying to do a bank reconciliation. I have multiple depreciable asset items purchased from one store that only shows the total of all these items on my bank statement.
These items all keep showing as an issue and won’t let me finalise the reconciliation. Manager keeps asking for statement period dates which are correct. Please help.
Also, how do I reconcile per transaction as I go, this might help?

If they were all in one transaction at the merchant, put them in one transaction with multiple line items in Manager.

As for reconciliation frequency, you can reconcile as often as you want. Just make sure you have pending/cleared status correct.
