Institutions that integrate with the financial system based on ERP number will have POs that are about to be sent to the vendor waiting in review until the ERP approves them and sends an ERP number.
This is done using the Import PO Approval job: the job receives an input file of POs that were exported to the ERP. for each PO the ERP might approve it – and include the ERP number, or reject it – and include the reject reason. Approved POs will automatically continue in the workflow.
The file of POs can be divided however the institution wants, for example one file per order or one file per vendor. It is also possible to have one file of approvals and one file of rejections. It does not matter what the file names are called, as long they are in the correct structure and have suffix “.xml”.
