When making a batch of payments to a number of suppliers in Sage for Education there is a posting to the Cash Book for EACH supplier. In other versions of Sage200 these are grouped such that there is a single posting to the cash book related to the whole batch (with individual debits to the supplier accounts). Grouping the cash posting makes bank reconciliation easier as there will only be one bank entry for the BACS batch, rather than a bank entry for each supplier.
Please could you provide more details, step by step and any anonymised screenshots would be appreciated.
