Finance document changes IDOC FIDCCH

Hello IDOC Experts

We have implemented FIDCC2 so that IDOCs are sent when an FI document is posted. We also need to send an IDOC when finance documents are changed. We have tried to implement idoc type FIDCCH but there is no IDOC being triggered when we change a finance document. I mean documents posted directly in SAP FI eg by FB01, FB70 etc and later changed by FB02 etc

Can anyone advise if it is possible to send an IDOC for changed SAP fi documents?

Thank you.

Regards
Michael
