How Can We Help?
A production line is the path a unit is built on. Each line is set up under
Administration and Setup → OJ Setup → PRODUCTION → Production Line: the list of lines is on
the left; pick one and press Edit (or New) to change the form on the right, then Save. Only
Description is required. For the vocabulary (lines, stations, parent lines) see
Stations & production lines.
What, where, who, when, why
| What | One form per production line: identity, how batching loads its carts (Cart Size, slots, levelling), which shifts it works, how it routes (parent, feeder, sequence), glass behaviour and shipping flags. |
| Where | Administration and Setup → OJ Setup → PRODUCTION → Production Line. The stations themselves live on the Production Stations screen, and the order you visit them in on Line-Station Routing. |
| Who | Whoever sets up production. The shop floor only meets this line as a name in pickers, batch carts and station views. |
| When | Before the first batch on the line; when cart sizes, shifts or sorting change; when a glass or feeder line is added; when a line is retired (Active). |
| Why it matters | Batching, cart/slot numbering and glass pairing all read these fields, and the forward scheduler books capacity per line using its shifts and parent links. A wrong Cart Size or an unticked shift shows up as mis-loaded carts or orders that never find a date. |
Active hides the lineThis screen lists active lines
only. If you untick Active and save, the line disappears from this screen (and from every line
picker) and cannot be switched back on here — ask your OpenJanela administrator. Delete removes the
line permanently.

Identity
| Field | What it does |
|---|---|
| ID | Given by the system when you save a new line. |
| Description | The line’s name in every line picker, batch and report. |
| Code | Stored; no effect found in the current version. |
| Active | Inactive lines are left out of every line list (see the warning above). |
Cart & Slots — how batching loads carts
When a batch is created, the units of each line are sorted (see Sort By), split into carts and given
a cart number and slot number. Each cart becomes one part of the batch.
| Field | What it does |
|---|---|
| Cart Size | How many units one cart holds. Number of carts = units ÷ Cart Size, rounded up. Always set it above 0 on a line that receives units. |
| Level (in the Shifts group) | Balances the carts. Off: carts are filled to Cart Size (25 units, size 12 → 12, 12, 1). On: the units are spread evenly over the same number of carts (→ 9, 9, 7). |
| Min Slot # | 0 = slots are numbered 1, 2, 3… in every cart. Above 0 = slots are numbered on from Min Slot # + 1 and keep counting across all of this line’s carts in the batch. |
| Max Slot # | Stored, but no upper limit is applied in the current version. |
| Assign Own Cart Slot | On by default; leave it on for normal lines. On a non-glass line with it off, the cart and slot numbers are worked out but not saved to the units. For glass lines see Glass below. |
| Building #, Warehouse, Ship Building | Stored; no effect found in the current version. |
Shifts — scheduling capacity
Shift 1, Shift 2, Shift 3 say which shifts this line works. When an order is
scheduled, each working day is tried shift by shift (1, then 2, then 3) for room at the line’s bottleneck
stations. A shift only counts on dates covered by one of its windows on the
Shift screen, which also gives its capacity %.
Tick a shift and give it a windowScheduling keeps looking
day by day until it finds room. A line with no ticked shift, or with ticked shifts that have no Shift
window covering the dates, never finds room.
day by day until it finds room. A line with no ticked shift, or with ticked shifts that have no Shift
window covering the dates, never finds room.
Routing
| Field | What it does |
|---|---|
| Sequence | When an order uses several lines, scheduling handles the lines in this order. |
| Feeder | A feeder line makes parts for another line. Its units are scheduled to finish LT to Next Line working days earlier than the order’s production finish date. The Create Batch screen lists feeder lines together with virtual sub-lines and glass lines, apart from the main lines. |
| LT to Next Line | Working days a feeder line finishes ahead (see Feeder). On a sub-line, the parent line’s Feeder and LT to Next Line are used instead of its own. |
| Transfer LT | Stored; no effect found in the current version. |
| Parent Line | Makes this line a sub-line of another (a line cannot be its own parent). The sub-line inherits the reports assigned to the parent’s stations, scheduling books its capacity together with the parent, and its Feeder/LT to Next Line come from the parent. None = a main line. |
| Has Sub-Lines | Changes how batching makes carts: instead of one set of carts for the line, the units are grouped by the station they go to, and each station’s own Cart Size, Batch Sequence, Min Slot # and Buffer are used (see Production Stations). Carts are always balanced on this path. |
Glass
| Field | What it does |
|---|---|
| Is Glass Line | Marks a glass / sealed-unit line. In batching, glass units on a glass line with Assign Own Cart Slot off take the same cart and slot as the unit they belong to; with it on they get their own carts and are only paired to their unit (same box number). Glass lines are left out of the Production Control Board’s line selector. |
| Glass Cart Size | Used by the glass machine pattern lists: a new glass cart starts when the slot count passes the largest Glass Cart Size among the batch’s lines. |
| Force Glass PL / Glass PL | When Force Glass PL is on and a Glass PL is picked, glass whose unit is built on this line is moved to the Glass PL line when the item’s bill of materials is built. |
Flags
| Field | What it does |
|---|---|
| Virtual | Not a physical line. Virtual lines with a parent are listed with the sub-lines on the Create Batch screen; the Production Control Board shows them combined into their parent. |
| Generate Shipping | A number, not a tick box. 0 = off. 1 = when the order is scheduled, this line’s units are recorded as inspected and waiting in the ship warehouse, and their stock is issued as shipped (when the series also has 1). 2 = when the batch is released, shipping records are created for this line’s units (a series set to 2 instead marks the whole item ready to ship). See Direct-to-shipping orders. |
| Min Days to Manufacture | Minimum production days; see Stations & production lines. |
| Sort By | Unit order before carts are filled: 0 = order, item, unit number; 1 = width (narrowest first), then order and item. Other values leave the units unsorted. |
Targets
Daily Target (units) and Remake Target (%) drive the target line and the Remakes KPI of the
Production Control Board. 0 = no target.
Worked example — a vinyl weld line with a glass feeder
| Field | Value | Why |
|---|---|---|
| Description / Active | “Weld Line 1” / on | Name shown in batch and PCB pickers; unticking Active hides the line everywhere. |
| Cart Size / Level | 12 / on | A 25-unit batch spreads over 3 carts as 9, 9, 7 instead of 12, 12, 1 — even workload per cart. |
| Sort By | 1 | Welding narrowest-first: units are sorted by width before carts are filled. |
| Shift 1 / Shift 2 | ticked / ticked | Two-shift line. Both shifts also need windows on the Shift screen, or scheduling finds no capacity. |
| Glass line “SU Line” | Feeder off, Is Glass Line on, Glass Cart Size 20, Assign Own Cart Slot off |
Sealed units take the same cart and slot as the window they belong to, and the pattern lists cut a new glass cart every 20 slots. |
| Generate Shipping | 0 | Units ship through the normal shipping flow, not direct-to-shipping. |
