There could be a number of reasons as to why your Aged Creditors is not matching your control account:
Have any journals been posted directly to the control account?
Use the transaction enquiry to search for transactions in the control account not from the purchase ledger.
Have your Analysis codes been set up correctly to use the Purchase Control Account? If they are not correctly debiting or crediting the Purchase Control account then this will cause differences.
Compare the transactions in the control accounts with the purchase ledger for the same period to identify any differences in value.
Are you comparing the 'Aged Creditors as at Date' report to the 'Aged Creditors as at Period' Report? These reports will potentially show different information due to Transactions dates not necessarily reflecting the period and years they have been posted to.
Are the Purchase Ledger and the Nominal Ledger in the same year? if the Purchase ledger has been moved forward then you may need to run the 'Aged Creditors as at Period' Report in Last year 12 to compare it against the Nominal in Current year 12.
