SAP Cash Management provides a program FQM_UPD_FLOW_TYPE to update Flow Type in Accounting Document.
As the program will set the Flow Types based on the master data definition (like G/L account, bank account), configuration data (like Payment program) and transaction data (mostly the accounting document itself), and the customizing (IMG path is: Financial Supply Chain Management > Cash and Liquidity Management > Cash Management > Flow Types > Assign Flow Types to G/L Accounts).
However, the program won't reset the flow types in the Accounting Documents automatically.
Here comes a program which help you to reset all the Flow Types in Accounting Documents which you can reset all Flow Types if you need to.
