Hi Dawn,
I believe for the purpose mentioned you could simply use report TPM13 - so called 'Subledger Cash Flows' - it provides you reporting on all flows (cash flow relevant and financial/ evaluation flows purely in GL) across all instruments in TRM, you can sort them by date, also create you preferred layouts according to your specific reporting requirements.
for more information, please refer to SAP help - Subledger Cash Flow / Position Flow List - External Accounts - SAP Library
hope it will help you.
Kind regards,
Renatas
