## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 27 "Confirm Management"](../codeunit/27.md) (1 call: `UpdateItemVariantAttributeFromItem → GetResponseOrDefault`)
- [Codeunit 46 "SelectionFilterManagement"](../codeunit/46.md) (1 call: `GetItemNoFilterText → AddQuotes`)

## Called by

- [Page 5734 "Item Category Attributes"](../page/5734.md) (5 calls: `ChangeDefaultValue → SearchCategoryItemsForAttribute`, `OnDeleteRecord → DeleteCategoryItemsAttributeValueMapping`, `OnDeleteRecord → SearchCategoryItemsForAttribute`, …)
- [Codeunit 2026 "Item Attr Populate"](../codeunit/2026.md) (2 calls: `GetFirstMatchingAvailableItemAttributeId → DoesValueExistInItemAttributeValues`, `SetItemCategory → InheritAttributesFromItemCategory`)
- [Codeunit 20405 "Qlty. Inspec. Gen. Rule Mgmt."](../codeunit/20405.md) (1 call: `DoesMatchItemAttributeFiltersOrNoFilter → FindItemsByAttributes`)
- [Table 2028 "MS - Image Analyzer Tags"](../table/2028.md) (1 call: `OnValidateAction → DoesValueExistInItemAttributeValues`)
- [Table 5401 "Item Variant"](../table/5401.md) (1 call: `OnInsert → InheritAttributesFromItem`)
- [Table 5722 "Item Category"](../table/5722.md) (1 call: `UpdateDeletedCategoryItems → DeleteItemAttributeValueMapping`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC28

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. 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: "codeunit", object_name: "Item Attribute Management")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
