Hi

In Oracle R12 2 5 Ebs Account Payables

Please can you assist with the below. Once an
invoice has been matched or coded> validated> and accounted. If there is
an error with the header level data (wrong date or inv number entered). The
invoice distribution lines are reversed (accounting goes to partial) and the
invoice date,  number & amount etc can then be modified.

However I have two below examples where this is not
happening. The invoice date and number fields are greyed out.
