## 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

#### Material label

`ISSUED` → `PRINTED` → `CONSUMED` → `CANCELLED`

Transitions:

- `ISSUED` -- Send to printer · First print --> `PRINTED`
- `PRINTED` -- Scanned into an inbound Slip (auto) --> `CONSUMED`
- `PRINTED` -- Cancel label — printed label --> `CANCELLED` (back)
- `ISSUED` -- Cancel label — unprinted label --> `CANCELLED` (back)

## Input

| # | Input | Type | Used in step |
| --- | --- | --- | --- |
| I-1 | Material receipt (GRN) · PO — Purchasing module | Source document | Pick the source document |
| I-2 | Production output — leftover material from production | Source document | Pick the source document |
| I-3 | Return / re-pack document | Source document | Pick the source document |
| I-4 | Item (package size) · Supplier · Printer · Label stock | Master data | Enter Qty to label · Qty / label; Print labels |
| I-5 | Label register — labels already issued | Data owned by this screen | Label inquiry: search labels |

## Step ↔ screen

| Step | Role | Screen |
| --- | --- | --- |
| Choose Source type · pick the source document (changing the document after quantities are entered needs confirmation and clears them) | Warehouse Staff (Warehouse Officer / Receiving Clerk) | Material Label Issue · Web |
| Choose Remainder rule (default Last label carries remainder) · enter Qty to label · Qty / label per line; Fully labelled lines have their quantity fields disabled | Warehouse Staff | Material 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) | Material Label Issue |
| Save as draft · Generate labels · Generate & print | Warehouse Staff | Material Label Issue · Web |
| Re-check Outstanding + generate ISSUED labels + write cumulative Labelled back to the source line — one transaction; if Outstanding is exceeded or anything fails, no label is created | System (auto) | Material Label Issue |
| Print labels (Printer · Copies · Label stock · Start at position) → label PRINTED, Prints + 1 | Warehouse Staff | Material Label Issue · Web |
| Label scanned into an inbound Slip → label CONSUMED | System (auto) | Inbound |
| Label inquiry · First print (one / several ISSUED labels, no Reprint reason needed) → label PRINTED, Prints + 1 | Warehouse Staff | Material Label Issue · Web |
| Label inquiry · Reprint (one / several PRINTED / CANCELLED / CONSUMED labels, one shared Reprint reason mandatory) — same label no., status unchanged, Prints + 1; the audit trail is written per label only when the print succeeds | Warehouse Staff | Material Label Issue · Web |
| Label inquiry · Cancel label (reason + physical-destruction confirmation mandatory; if the source document is reversed, cancel with reason Receipt reversed) — not an approval step: the Cancel label button is shown to Manager · QA only | Warehouse Manager · QA (Warehouse Supervisor / QA) | Material Label Issue · Web |

## Output

| # | Output | Produced when |
| --- | --- | --- |
| O-1 | Draft (Save as draft), no labels generated yet | Save as draft chosen |
| O-2 | Source 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 goods | Printed successfully |
| O-6 | Label = `CONSUMED`, can no longer be cancelled | Label scanned into an inbound Slip |
| O-7 | Reprint failed — Prints and audit unchanged | Printer could not print during Reprint |
| O-8 | Label reprinted, same label no. | Reprint succeeded |
| O-9 | Labels stay `ISSUED` (print failed), print count unchanged | Printer could not print on the first print |
| O-10 | Label = `PRINTED` (first print) applied to the goods | Print tem `ISSUED` succeeds |
| O-11 | Cancel blocked — label `CONSUMED` / `CANCELLED` unchanged | Label already scanned into stock, or already cancelled |
