Sending changes of FI documents with WfXML

[Gordan]

Hello all,=20
 
We are receiving invoices from our vendors electronically in our SAP =
system
via SAP Business Connector.=20
We would like to send info to vendor that inbound document is changed.=20
Change of document is done through custom transaction (modification of =
FB02)
and after that with report (automatic payment).=20
Only standard fields are changed (BSEG-ZLSPR manually, BSEG-AUGBL and
BSEG-AUGDT with report).=20
 
Will it be appropriate to use Workflow to monitor changes of FI =
documents
and send WfXML documents to SAP BC?=20
What do I need to customize for that option?=20
 
TIA,
 
Gordan
