A standard report providing information in this way is not available in Dimensions.
However, there are ways of reporting on the transactions that may help you with this:
Use the Creditors/Suppliers Allocation Report or
Extract Purchase Ledger transactions using AOI.
Creditors/Suppliers Allocation Report
This report shows you which payments have been allocated to which invoices and when.
With the Ribbon style menu, click Creditors, Allocation and select Cash Allocation.
With the Classic/Module menu style, from the navigation bar, click Purchase Ledger, Allocations, Allocate.
Click the Printer icon on the Allocations Allocate window
Select the destination output for the report.
Click Reporting Period and select the period you want to run the report for.
Click Print (green tick)
Using AOI
If you use AOI, you could use the AOI ACCESS tab option and select the Purchase Ledger Transactions template to extract in to Excel the relevant supplier transactions including details of the allocations.
A further alternative, if this is something you need to do on a regular basis, is to consider commissioning a bespoke report. If you wish to pursue this, then please contact your Access Account Manager who will be pleased to discuss your requirements.
