## Properties

| Property | Value |
|---|---|
| Caption | Date Compr. Register |
| DataClassification | CustomerContent |

## 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 |
|---|---|---|---|---|
| 1 | No. | Integer | Specifies the number of the involved entry or record, according to the specified number series. |  |
| 2 | Creation Date | Date | Specifies the date that the date compression took place. |  |
| 3 | Table Caption | Text[250] | Specifies the name of the table that was compressed. | FlowField: lookup(AllObjWithCaption."Object Caption" where("Object Type" = const(Table), "Object ID" = field("Table ID"))); not editable |
| 4 | Period Length | Option | Specifies the time interval of entries combined into one for the period defined in the Starting Date and Ending Date fields in the batch job. | OptionCaption: Day,Week,Month,Quarter,Year,Period |
| 5 | Ending Date | Date | Specifies the last date in the period for which entries were compressed. |  |
| 6 | No. of New Records | Integer | Specifies the number of new entries that were created by the date compression. |  |
| 7 | No. Records Deleted | Integer | Specifies the number of entries that were deleted during the date compression. |  |
| 8 | User ID | Code[50] | Specifies the ID of the user who posted the entry, to be used, for example, in the change log. | TableRelation User."User Name"; DataClassification EndUserIdentifiableInformation |
| 9 | Filter | Text[250] | Specifies the filters that were placed on the date compression. |  |
| 10 | Starting Date | Date | Specifies the first date in the period for which entries were compressed. |  |
| 11 | Table ID | Integer | Specifies the number of the table that was compressed. | TableRelation AllObjWithCaption."Object ID" where("Object Type" = const(Table)) |
| 12 | Register No. | Integer | Specifies the number of the register that was created by the date compression and that contains the compressed entries. | TableRelation [Table 240 "Resource Register"](../table/240.md), [Table 45 "G/L Register"](../table/45.md), [Table 46 "Item Register"](../table/46.md) (if ("Table ID" = const(17)) "G/L Register" else if ("Table ID" = const(21)) "G/L Register" else if ("Table ID" = const(25)) "G/L Register" else if ("Table ID" = const(254)) "G/L Register" else if ("Table ID" = const(32)) "Item Register" else if ("Table ID" = const(203)) "Resource Register" else if (...) |
| 13 | Source Code | Code[10] | Specifies the source code that specifies where the entry was created. | TableRelation [Table 230 "Source Code"](../table/230.md) (Source Code) |
| 14 | Retain Field Contents | Text[80] | Specifies a list of the fields whose contents the user chose to retain in the date compression. |  |
| 15 | Retain Totals | Text[80] | Specifies a list of the quantity fields that the user chose to retain when they ran the date compression batch job. |  |

## 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 703 "Find Record Management"](../codeunit/703.md) (1 call: `GetLastEntryNo → GetLastEntryIntFieldValue`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC29

## 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: "table", object_name: "Date Compr. Register")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
