BeytullahCengiz88 c72c0ad685 Add CMFRT coding standards documentation and examples 
- Introduced guidelines for "one codeunit one global function" architecture to enforce single responsibility in AL code.
- Added best practices and anti-patterns for adding parameters via overloads to maintain backward compatibility.
- Documented the importance of never deleting members in AL and always marking them as obsolete.
- Established the requirement for OnBefore and OnAfter integration events for global procedures to enhance extensibility.
- Defined naming conventions for CMFRT objects, including prefixes and object ID ranges to avoid conflicts.
- Implemented patterns for case statements to ensure all cases are handled, including the necessity of an else clause.
- Introduced the interface injection pattern to allow pluggable operations in table-level code.
- Recommended using Confirm Management for user confirmations to improve testability.
- Established a three-permission set pattern for security to ensure proper access control.
- Created a review skill for CMFRT AL standards to automate compliance checks against established guidelines.

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.
