# DynamicValidationService

**Kind:** Class

**Source:** `Pams/Web/Pams.Web/Client/app/services/configurations/dynamic-validation/dynamic-validation.service.ts` (line 86)

**Part of:** [Pams](subsystem-pams)

`DynamicValidationService` manages dynamic validation configuration data in the client application. It retrieves lookup modules, submodules, and properties, and saves or loads mandatory-field settings for a selected module.

## Methods

| Method | Signature | Returns |
|---|---|---|
| `getlookupModules` | `getlookupModules()` | `void` |
| `getlookupSubModules` | `getlookupSubModules(id: undefined)` | `void` |
| `getProperties` | `getProperties(id: undefined)` | `void` |
| `saveMandatoryFields` | `saveMandatoryFields(list: undefined)` | `void` |
| `getMandatoryFieldsByModule` | `getMandatoryFieldsByModule(moduleId: number)` | `void` |

## Usage

```ts
import { Component, OnInit } from '@angular/core';
import { DynamicValidationService } from './dynamic-validation.service';

@Component({
  selector: 'app-mandatory-fields',
  template: ''
})
export class MandatoryFieldsComponent implements OnInit {
  modules: unknown[] = [];
  mandatoryFields: unknown[] = [];

  constructor(
    private readonly dynamicValidationService: DynamicValidationService
  ) {}

  ngOnInit(): void {
    this.dynamicValidationService.getlookupModules().subscribe((modules) => {
      this.modules = modules;
    });
  }

  loadMandatoryFields(module: unknown): void {
    this.dynamicValidationService
      .getMandatoryFieldsByModule(module)
      .subscribe((fields) => {
        this.mandatoryFields = fields;
      });
  }

  saveMandatoryFields(fields: unknown): void {
    this.dynamicValidationService.saveMandatoryFields(fields).subscribe();
  }
}
```

## AI Coding Instructions

- Keep calls to `getlookupModules`, `getlookupSubModules`, and `getProperties` in the configuration workflow that selects validation targets.
- Load existing values with `getMandatoryFieldsByModule` before editing mandatory-field configuration.
- Send the payload expected by `saveMandatoryFields`; preserve the module, submodule, and property identifiers supplied by the UI.
- Handle observable success and error paths in consuming components, especially when saving validation settings.
