Change credit and contact details on the right record, with evidence

**Objective:** Apply `{changes}` to the customer `{customer-name}`.

Pass `{company}` as the company argument on every call. If `{company}` is empty, leave the company argument out so the connector's default company is used.

**Step 1: Resolve the customer**

Call `business-central-get-customer` with name.contains set to `{customer-name}`. If several match, list them and stop. Keep customer-number.

**Step 2: Evidence for credit changes**

If `{changes}` touches credit-limit or blocked, first gather: balance, balance-due, current credit-limit; `business-central-get-posted-sales-invoice` with sell-to-customer-number and remaining-amount.min 0.01 for overdue amounts; `business-central-get-detailed-customer-ledger` with document-type Payment and posting-date.from 180 days ago for recent payments; `business-central-get-sales-transaction` with document-type Order for open orders a block would stop.

**Step 3: Contacts**

If `{changes}` concerns a person at the customer, call `business-central-get-contact` with company-name set to the customer name and find the person. That change goes to `business-central-update-contact` with the contact number, not to the customer.

**Step 4: Preview and confirm**

Show a before-and-after table for each field, plus the credit evidence when relevant. Ask for confirmation.

**Step 5: Apply**

After confirmation call `business-central-update-customer` once with number set to the customer number and only the fields that change, and `business-central-update-contact` once per contact changed.

**Step 6: Confirm the result**

Re-read with `business-central-get-customer` and show the new values.

**Rules & Guidelines:**

* Do not call any create or update tool until the user has confirmed the exact values shown in the preview.
* Blocking a customer with open orders stops those orders from shipping; say so in the preview.

**Validation:**

* If `{changes}` is unclear, ask before reading anything else.
