Services and Operation Groups

A customer does not ask for "an oil change, a filter change, a brake inspection and a fluid top-up". They ask for the 10,000-kilometre service, and they want one price for it. The service — خدمة in the Arabic menu, Operation in the English one — is how the workshop sells a bundle like that.

A service is a named package of tasks, with a decision attached: does the customer see the tasks priced one by one, or does the package carry a single price and the tasks come along silently?

Two words for the same thing

The English menu says Operation; the Arabic menu and every Arabic label say خدمة, a service. They are the same file. Throughout this documentation "service" and "operation group" both mean this record — never a running job.

Both Files Are Catalogue Masters

It is worth being blunt about the relationship, because the two words sound like different stages of the same thing and they are not.

• A task is the atom: one repair step, with a standard duration, a labour rate and a bill of materials.
• A service is a bundle of tasks with a price policy on top.

Neither one is the work being done. Both are things you set up once and reuse. The performed work is a line on a job order and a clocked line on the shop-floor time sheet — never a task record and never a service record.

The Screen

Basic Information

Field	Arabic label	What it does
Code, Group, Name1, Name2	الكود، المجموعة، الاسم العربي، الاسم الإنجليزي	Identity. Name1 Arabic, Name2 English.
Item Brand	الماركة	The marque this service belongs to. It also governs the model price table — see below.
Item Model	الموديل	The model this service belongs to.
Pricing strategy	سياسه التسعير	Per Line (لكل سطر) or Total ( الإجمالي). The fork this whole page is about.
Service Item	صنف الخدمة	The item invoiced for the package.
Total	إجمالي السعر	The package price, used when the strategy is Total.
Manufacturer Suggested Retail Total Price	إجمالي سعر المورد	The manufacturer's package price, used instead when the installation runs the MSRP pricing strategy.
Tax Plan	سياسة الضريبة	The tax treatment carried with the service.

The Tasks Grid

Column	Arabic label	What it holds
Task	المهمة	The member task. Required on every row — a service with an empty task column cannot be saved.
Total Hours	المدة	The hours this task contributes to the package.
Hour Price	سعر الساعة	The rate for those hours.
Manufacturer Suggested Retail Hour Price	سعر ساعة المورد	The manufacturer's rate.
Total	إجمالي السعر	Hours × rate.
Manufacturer Suggested Retail Total Price	إجمالي سعر المورد	The same, at the manufacturer's rate.

The Model Price Table

Below the tasks grid sits a button, Collect Models (تجميع الموديلات), and a grid headed price for all models (أسعار الخدمة لكل الموديلات).

Column	Arabic label	What it holds
Item Brand	الماركة	The marque.
Item Model	الموديل	The model this price applies to.
Total	إجمالي السعر	The package price for that model.
Manufacturer Suggested Retail Total Price	إجمالي سعر المورد	The manufacturer's package price for that model.
Recur Every KM	تكرر كل / كم	How often this service comes round on that model.

Pressing Collect Models saves typing: it reads the marque in the header and fills the grid with one row for every model that marque owns. At Al-Sahra, with BRD-NAWA in the header, one press produces rows for the Saif 1.6, the Rimal 2.4 and the Nakhla — and you then type a price against each.

Two rules govern the grid at save time. A row whose brand is not the header's brand is refused when you commit. And after a successful commit, each row's brand is filled in from its model, so rows produced by the button keep themselves tidy.

The brand column does not select anything

When the system looks for the price of this service on a particular car, it matches on the model alone. The Item Brand column in the model price table is displayed, is validated against the header, and is then ignored by the lookup.

Consequence: two rows for the same model with different brands are indistinguishable to the matcher, and the first one always wins. Keep one row per model.

Actions on this screen

• Collect Models (تجميع الموديلات) — save the service first. The button replaces the model price table with one row per model of the header's Item Brand, each with the brand filled and no price; rows you had already typed are discarded, so press it before you enter prices, not after.

Per Line or Total — the Fork That Matters

The Pricing strategy field decides which level of the record carries the money, and it does so by zeroing the other one. This is not a display preference; the numbers are actually cleared when you save.

Per Line — each task row is priced in its own right: hours × hour price. The header's Total is forced to zero. Use this when the customer should see the components: "oil change 120, brake pads 180, alignment 60".

Total — the header's Total is the price of the package, and every task row's price is forced to zero. Use this when you sell "the 10,000 km service" for one figure and do not want the parts of it argued over. With this strategy, the price the job order actually takes is the row of the model price table that matches the vehicle's model, and whether it reads the ordinary Total column or the manufacturer's column depends on the installation-wide Service Price Strategy setting.

Switching strategy destroys the other side's prices

Because the losing side is zeroed on save, changing an existing service from Per Line to Total wipes the per-task prices, and changing it back does not bring them back. Decide the strategy when you create the service, and if you must change it, expect to retype prices.

How a Service Reaches a Job Order

There is exactly one grid for work on a job order, and both files feed it. A service goes in as a header row; the tasks it contains go in underneath it as child rows. A task that is not part of any package goes in on its own, with no parent.

So Al-Sahra's job order could equally have looked like this — a service row with four children and one free-standing task:

▸ SRV-10K   Ten-thousand kilometre service   ← the service, a header row
    TSK-OIL   Engine oil and filter change   ← its tasks, child rows
    TSK-BRK   Front brake pad replacement
    TSK-ALN   Wheel alignment
  TSK-AC     A/C compressor replacement      ← a task on its own

Four rules are enforced when you save the document:

If you do this	The document refuses with
Put a service and a task on the same row	Task and operation not allowed at the same line
Enter a service with no child rows under it	Operation must have sub-rows
Put a service on a row that is itself a child	It is slave line and must not have operations
Repeat the same task twice in one job order	The task {0} cannot be repeated for the same job order

That last rule is worth remembering when you build packages: if two of your services share a task, they cannot both go on the same job order.

The pricing fork follows the rows onto the document. A service's header row has its hours, hour price and count zeroed — a package header is not billed by the hour. Its child rows are priced only if the parent service is Per Line; if the parent is Total, the children are zeroed too and the package price stands alone — and which payer carries that price is then settled by the payer split on the document.

Building a Service

1. Build the tasks first. A service is nothing without them, and every row must name one.
2. Create the service, name it the way a customer would ask for it, and set the marque in the header.
3. Choose the Pricing strategy now, before anyone uses the record.
4. Add the member tasks. Under Per Line, give each its hours and rate; under Total, put the package price in the header and leave the rows alone.
5. If you price the package differently by model, press Collect Models and fill in the Total column row by row — one row per model, no duplicates.
6. Add a Recur Every KM on the model rows if the package is a scheduled service that comes round with mileage.
