How to update supporting references after the create accounting has been run

Hello,

We have the following case:

1/ Create an invoice, and enter a value in a DFF at distribution level

2/ Create accounting, and the value from the DFF is stored in a supporting reference

3/ Update the DFF value at invoice distribution level

=> how to update the supporting reference in GL?

Thanks for your help.

Best regards,
