Source: https://help.smartfact.ai/automation/guides/purchasing-assistance Audience: Author Type a supplier choice rule in plain English, answer the AI's question about the missing details, inspect the complete proposed rule and save it deliberately as a draft. ## Plain English to a checked draft 1. **Load the current purchasing terms** Load the current purchasing terms Load the November purchasing terms from SmartFACT Purchasing. Pennine Fasteners' box of 100 M8 bolts is now approved alongside Calder's, and no rule yet says which to try first. 2. **Choose Add supplier choice rule** Choose Add supplier choice rule Choose Add supplier choice rule under Change to describe, so the proposal covers both when the rule applies and which supplier items it uses. 3. **Type the requirement in plain English** Type the requirement in plain English Type the requirement as the team wrote it: for M8-ZP, try the approved BOLT-M8-100 item first, then PF-M8-100 if the first is unavailable. 4. **Ask for a proposal** Ask for a proposal Ask for a proposal. The AI replies with a question instead of guessing: every rule needs a name and a precedence, and the requirement gives neither. 5. **Add the details the AI asked for** Add the details the AI asked for Keep the requirement and answer the question: call the rule M8 bolts from Calder, then Pennine, and give it precedence 10. 6. **Ask for the complete proposal** Ask for the complete proposal Ask again. The AI now returns a complete supplier choice rule. Nothing is saved until you choose to save it. 7. **Read the restatement of the rule** Read the restatement of the rule Read the restatement. It says in plain words when the rule applies, when the item code is M8-ZP, and which parts it sets: the rule name and precedence, and the complete supplier choice. 8. **Inspect the proposed condition** Inspect the proposed condition Inspect the condition in the same controls Purchasing uses: the item code is exactly M8-ZP. 9. **Check what will be saved** Check what will be saved Read what the rule will save, field by field. The decision and both supplier items are shown by name. 10. **Check the rule name and precedence** Check the rule name and precedence Check the rule is called M8 bolts from Calder, then Pennine, with precedence 10. 11. **Check the supplier items and their order** Check the supplier items and their order Check the decision: use the listed supplier items in priority order, Calder's BOLT-M8-100 first and Pennine's PF-M8-100 second. When Purchasing prepares an order it uses the first one that is still active. 12. **Confirm you checked the whole proposal** Confirm you checked the whole proposal Confirm that you checked the condition and every value. Purchasing still validates the complete terms when it saves. 13. **Save the proposal as a draft** Save the proposal as a draft Save the proposal as a draft. Saving does not approve, release or run the rule, and rules never approve an order: the expected results, proof and an independent review come next. [Watch or practise this chapter](https://help.smartfact.ai/automation/demo?guide=purchasing-assistance&chapter=assisted-rule&audience=office) Only a draft was saved.
