Hi Andre
It has been difficult to reproduce this issue. We have had a few calls with MS on this.
Sometimes the users get it as soon as they confirm an inbound load. They do use advance warehousing. I'm not sure where the PO distribution are 'falling over'. They do have multiple PO's split across invoices, and then some lines with partial receipts and partial quantities spread across multiple invoices. I do not think it is because of this as this is standard.
There is a custom job updating PO prices to match shipping files, and sometimes this would cause distribution errors (due to charges allocated to all lines I think) and other times no errors.
I got error on error posting 2 large invoices (1300+ lines and 2000+ lines), but when I split it up into multiple invoices I got no errors on posting. This makes no sense and it just shows me this error is random. I have tried to find a pattern, but no success yet.
I do think this is due to custom code as mentioned before, as I have also not seen this at any other client but this one.
Kind regards
Michelle
