## 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 5402 "Unit of Measure Management"](../codeunit/5402.md) (4 calls: `CalcAssemblyItem → GetQtyPerUnitOfMeasure`, `CalcAssemblyItem → GetResQtyPerUnitOfMeasure`, `DoCalcAssemblyItemPrice → GetQtyPerUnitOfMeasure`, …)
- [Codeunit 5804 "ItemCostManagement"](../codeunit/5804.md) (1 call: `CalcItem → UpdateStdCostShares`)
- [Codeunit 5836 "Cost Calculation Management"](../codeunit/5836.md) (1 call: `GetResCost → CalcDirUnitCost`)
- [Codeunit 7001 "Price Calculation Mgt."](../codeunit/7001.md) (1 call: `FindResourceCost → GetHandler`)

## Called by

- [Page 916 "Assembly Order Statistics"](../page/916.md) (1 call: `OnAfterGetRecord → CalcAsmOrderStatistics`)
- [Page 923 "Posted Asm. Order Statistics"](../page/923.md) (1 call: `OnAfterGetRecord → CalcPostedAsmOrderStatistics`)
- [Table 900 "Assembly Header"](../table/900.md) (1 call: `UpdateUnitCost → CalcOverHeadAmt`)

## Across versions

- Present in: BC26-30
- Changed (declaration) in: BC27

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: "Calculate Assembly Cost")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
