SALES_DOC_FLOW
Data Description
The SALES_DOC_FLOW event can be used for extracting VBFA data to map the entire sales-document flow—from quotation and order through delivery, invoice, credit note and return—displaying each predecessor–successor link with its current status.
Potential Use Cases
This event could be used in the following scenarios:
Spotting any sales document that still lacks its expected follow-on
Flagging broken, cancelled or reversed chains for swift remediation
Alerting when a step in the sales flow breaches its SLA
Trending lead-times between document types to uncover bottlenecks
Metric Filters
Administrator->Metric Filters->More->Sales Document Flow

A filter entry is mandatory: specify the combination of Pre-Document Category, Pre-Document, Sub-Document Category, Sub-Document and Document-Flow Level you wish to capture. Each of these fields accepts the wildcard ‘*’ if you want to include every value.
SAP Navigation
Log on to the managed SAP system and run SE16 or SE16N to display table VBFA.
To view the document flow for one document, open it in the relevant transaction (for example VA03, VL03N or VF03) and click the Document Flow icon.
