clsTaskBusinessRules¶

clsTaskBusinessRules implements the shared task validation rules invoked by the BOF rules engine during save. It is the one component in this library that reaches directly into the data layer (ValidSourceCategory) rather than delegating to a code-table business object — a coupling flagged in source as a MUSTDO.

Purpose¶

Validate that a task's source system / category code combination is registered in TASK_CATEGORY_CODE (BR-005, SQL-005).
Enforce that a task's date is current or future, except for batch-created tasks (BR-006, BR-007).
Surface a non-blocking warning when AssignTaskDate has auto-shifted a due date (BR-008).

Context¶

Namespace: SAIF.Business.Tasks
Assembly/package: SAIF.Business.Tasks (embedded in the LegalMaintenance web deployment)

Public members¶

Member	Signature	Purpose
`ValidSourceCategory`	`Shared Function ValidSourceCategory(target As Object, e As clsRuleArgs) As Boolean`	Runs a scalar `COUNT(*)` against `TASK_CATEGORY_CODE` to confirm the source/category pairing is valid (BR-005, SQL-005); a zero count fails at `RuleCheckLevel.LevelThree` unless the descendant's `OverrideRules` converts the result.
`CheckDate`	`Shared Function CheckDate(target As Object, e As clsRuleArgs) As Boolean`	Validates the task date is current or future, skipping the check for batch-created tasks (BR-006, BR-007).
`CheckDateModified`	`Shared Function CheckDateModified(target As Object, e As clsRuleArgs) As Boolean`	Raises a non-blocking `RuleType.Warning` message when the task date was auto-shifted by `AssignTaskDate` (BR-008).

Behavioral notes¶

All three rule functions are decorated with <RuleData(...)>, the BOF rules-engine registration attribute.
ValidSourceCategory issues its own ad-hoc query directly against the target task's DPI rather than delegating to clsTaskCategoryCode/clsTaskCategoryCodeCollection — flagged in source as a MUSTDO to replace with a code-table call*.

Constraints and usage notes¶

All three functions match the BOF rule delegate signature (target As Object, e As clsRuleArgs) As Boolean and are registered via clsTask.AddBusinessRules.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
