Intercompany AR Invoicing - Error monitoring

We are having challenges monitoring Intercompany AR invoicing errors.

INCIAR: Create Intercompany AR Invoices

If the program runs into errors (the most common one we encounter is related to transfer price), it generates a message in the log file. So we are having to scroll through lots of log file text to identify issues.

I am wondering if there is a better way to monitor it? Are these errors stored in any table (perhaps in MTL_MATERIAL_TRANSACTIONS which is the source of these transactions)?

If there is at least a flag in a table somewhere that keeps track of all the errors or unprocessed intercompany invoice transactions, we will be able to write an alert to monitor those errors.
