## How to read

- Every box on the diagram has a code `Bxx`, numbered in flow order (from the start event, following the arrows).
- "Goes to" lists every arrow leaving the box; text in square brackets is that arrow's condition label.
- "Optional branch" = a dashed arrow on the diagram: may be done or skipped.
- "Data" boxes in the Input lane are incoming data; in the Output lane they are results / end points of the flow.

## Status lifecycle

#### FG QR label (finished-goods QR label)

`ISSUED` → `PRINTED` → `SCANNED` → `CANCELLED`

Transitions:

- `ISSUED` -- Send to printer · First print --> `PRINTED`
- `PRINTED` -- QR scanned · Slip re-approved (auto) --> `SCANNED`
- `PRINTED` -- Cancel label — printed label --> `CANCELLED` (back)
- `ISSUED` -- Cancel label — unprinted label --> `CANCELLED` (back)
- `SCANNED` -- Cancel / Delete Product Income Slip (inbound reversal) --> `PRINTED` (back)

## Input

| # | Input | Type | Used in step |
| --- | --- | --- | --- |
| I-1 | Product Income Request — created from the Sales Order (Product Income flow); Work order no. is only a reference field on the header | Inbound request | Select Inbound request |
| I-2 | Subcontract inbound — Purchasing / Production | Inbound request | Select Inbound request |
| I-3 | Return / re-pack inbound | Inbound request | Select Inbound request |
| I-4 | Item (variant · carton pack) · Warehouse · Printer · Label stock | Master data | Enter Qty to label · Qty / label; Print labels |
| I-5 | Label register — QR labels generated | Data owned by this screen | Label inquiry: search labels |
| I-6 | Product Income Slip: Cancel · Delete SAVED Slip · remove label line from Slip (inbound reversal) | Event from the Product Income screen | Tem SCANNED → PRINTED |
| I-7 | Product Income Slip CANCELLED is re-approved | Event from the Product Income screen | Label still PRINTED, not re-scanned? |

## Step ↔ screen

| Step | Role | Screen |
| --- | --- | --- |
| Select Inbound type · select the Inbound request through the picker (search by Request no. · Warehouse · Request date) — only requests with Outstanding qty, a Product Income Request must be SUBMITTED; header is read-only; changing the request reloads the lines and clears entered quantities | Warehouse Staff (Packing Operator) | Product Label Issue · Web |
| Select the Remainder rule (default Last label carries remainder) · enter Qty to label · Qty / label per line (bulk: All remaining qty, Qty per label = carton pack); Fully labelled lines have their quantity fields locked | Warehouse Staff (Packing Operator) | Product Label Issue · Web |
| Line checks (CR-10: Qty to label ≤ Outstanding · Qty / label ≤ Qty to label · Block rule must divide evenly) · label count (CR-09) | System (auto) | Product Label Issue |
| Save as draft · Generate labels · Generate & print (preview the label and the QR payload `FG \| item \| V:variant \| Q:qty \| U:uom \| S:serial \| R:request`) | Warehouse Staff (Packing Operator) | Product Label Issue · Web |
| Re-check Outstanding + generate ISSUED labels (label no. and serial unique, even when several packing lines generate at once) + write cumulative Labelled back to the request line — one transaction; exceeding Outstanding or any error generates no label. The QR Qty is fixed — if wrong, cancel the label and reissue | System (auto) | Product Label Issue |
| Print labels (Printer · Copies · Label stock · Start at position) → label PRINTED, Prints + 1; apply one label per carton / pallet | Warehouse Staff (Packing Operator) | Product Label Issue · Web |
| Scan the QR of a PRINTED label at put-away | Warehouse Staff (Warehouse Officer) | Product Income · Mobile |
| Label PRINTED and serial still usable: load exactly the QR Qty into the Slip (Qty field locked, not editable) · serial used up · label PRINTED → SCANNED. Serial already used or label cancelled (including a reprinted CANCELLED label): scan rejected, no Qty loaded, logged — in the same transaction as consuming the serial | System (auto) | Product Income |
| Label inquiry · First print (one / several ISSUED labels, no Reprint reason needed) → label PRINTED, Prints + 1 | Warehouse Staff | Product Label Issue · Web |
| Label inquiry · Reprint (one or more PRINTED / SCANNED / CANCELLED labels, one shared mandatory Reprint reason) — keeps label no. + serial, status unchanged, Prints + 1, no additional postable label; the audit trail is written per label only when printing succeeds | Warehouse Staff | Product Label Issue · Web |
| Label inquiry · Cancel label (mandatory reason + confirmation that the physical label was destroyed; if the inbound request is cancelled, cancel with reason Inbound request cancelled) — not an approval step: the Cancel label button is shown only to Manager · QA; SCANNED labels are blocked, cancel the Product Income Slip first | Warehouse Manager · QA (Warehouse Supervisor / QA) | Product Label Issue · Web |
| Product Income Slip cancelled, SAVED Slip deleted or label line removed from the Slip (inbound reversal) → label SCANNED → PRINTED, serial reopened (can be re-scanned or cancelled), audit trail written | System (auto) | Product Income |
| CANCELLED Product Income Slip re-approved: label still PRINTED and not re-scanned → label PRINTED → SCANNED, serial used up; label already scanned into another Slip or cancelled → re-approve blocked | System (auto) | Product Income |

## Output

| # | Output | Produced when |
| --- | --- | --- |
| O-1 | Draft (Save as draft), no labels generated yet | Save as draft chosen |
| O-2 | Request line: cumulative Labelled → Outstanding for the next pass | Labels generated successfully |
| O-3 | Label = `ISSUED` not yet printed, print later from Label inquiry | Generate labels chosen (no immediate print) |
| O-4 | Labels stay `ISSUED`, print count unchanged | Printer could not print |
| O-5 | Label = `PRINTED` applied to the carton / pallet | Printed successfully |
| O-6 | Scan rejected — duplicate serial / cancelled label, no Qty loaded, logged | A QR is scanned whose serial is already used, or the label is no longer PRINTED |
| O-7 | Label = `SCANNED` — to cancel, reverse the inbound first | First QR scan in Product Income |
| O-8 | Reprint failed — Prints and audit unchanged | Printer could not print during Reprint |
| O-9 | Label reprinted with the same label no. + serial, no new label | Reprint succeeded |
| O-10 | Labels stay `ISSUED` (print failed), print count unchanged | Printer could not print on the first print |
| O-11 | Label = `PRINTED` (first print) applied to the carton / pallet | Print tem `ISSUED` succeeds |
| O-12 | Cancel blocked — label `SCANNED` (reverse the inbound first) / `CANCELLED` unchanged | Label already scanned into stock, or already cancelled |
| O-13 | Keep label — label status unchanged | Canceller chose Keep label |
| O-14 | Label = `CANCELLED`; request line Outstanding goes back up | Cancel label with reason + physical-destruction confirmation |
| O-15 | Label = `PRINTED` — can be re-scanned or cancelled | The label's Product Income Slip is cancelled / deleted, or the label line is removed from the Slip |
| O-16 | Re-approve blocked — label already scanned into another Slip / cancelled | Re-approving a CANCELLED Slip when the label is no longer PRINTED |
| O-17 | Label = `SCANNED` again with the re-approved Slip | Re-approving a CANCELLED Slip while the label is still PRINTED |
