How can I see the field "Status" of a Document flow by each item?

I am using VBUP, but it brings me the general status, I want to see the status for each item in the document flow.
"VBUP"."GBSTA" -> Overall status
"VBUP"."LFSTA" -> Delivery status
“VBUP”.”LFGSA” -> Overall deliv.status
I want to be able to see the status for each line, for example, the Delivery lines I want to know what status they have, but in Completed, Open, Being processed
From what I see the possible states in VBUP are A, B and C, but if we look at the status in the document flow, there are many more states than letters. Like Completed, Open, Canceled, Cleared, etc.
When I see which table the Status field comes from, I see that it comes from the DOCUMENT_FLOW_ALV_STRUC structure and the STATUS field. But I can't find how to see that STATUS field when consulting the VBUP.
Thanks you for your help
