Extends [Customer](../table/18.md).

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 8010 | Cust. Subscription Contracts | Integer | Specifies the number of Customer Subscription Contracts that have been registered for the customer. <small>via [Page extension 8000 "Contract Sales H. Sell Factbox"](../pageextension/8000.md)</small> | FlowField: count("Customer Subscription Contract" where("Sell-to Customer No." = field("No."), Active = filter(true))); not editable |
| 8011 | Subscription Headers | Integer | Specifies the number of Subscriptions that have been registered for the customer. <small>via [Page extension 8000 "Contract Sales H. Sell Factbox"](../pageextension/8000.md)</small> | FlowField: count("Subscription Header" where("End-User Customer No." = field("No."))); not editable |

## Ask your agent

Procedure bodies are not stored here (D10). For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "tableextension", object_name: "Contracts Customer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
