# CMFRT naming prefix

## Description

Every object, field, and procedure in a CMFRT extension must carry the `CMFRT XXX` prefix, where `XXX` is the product or customer abbreviation (for example `GD` for Geodynamics, `BA` for Batch Automation, `JO` for Jobs). The prefix applies to tables, table extensions, pages, page extensions, codeunits, interfaces, reports, enum values, and to all global and local procedures. Object and field names use the three-part form `CMFRT <ABBR> <Descriptive Name>` with spaces. Procedure names use the concatenated form `CMFRT<ABBR><ProcedureName>` with no spaces.

## Best Practice

Name every object `"CMFRT <ABBR> <Name>"` — for example `"CMFRT GD Job"` or `"CMFRT GD POI"`. Name every field `"CMFRT <ABBR> <FieldName>"` — for example `"CMFRT GD POI ID"`. Name every procedure `CMFRT<ABBR><ProcedureName>` — for example `CMFRTGDCalculatePOIDistance`. The procedure name must be self-describing: a reader must understand what the procedure does without reading its body. Local procedures follow the same rule.

See sample: `cmfrt-naming-prefix.good.al`.

## Anti Pattern

Naming objects, fields, or procedures without the CMFRT prefix — for example `procedure CalculateDiscount()` or `field(50000; "Amount"; Decimal)`. Unprefixed members collide with base application fields, break the reviewer's ability to identify extension-owned members, and violate the astena naming convention enforced across all CMFRT extensions.

See sample: `cmfrt-naming-prefix.bad.al`.
