# No Series Validation Patterns - AL Code Examples

This sample demonstrates implementing comprehensive validation patterns for number sequence integrity in Business Central.

## Basic Validation Framework

```al
// Core validation interface for no series
interface INoSeriesValidator
{
    procedure ValidateFormat(SeriesCode: Code[20]; NumberValue: Code[20]): Boolean;
    procedure ValidateSequence(SeriesCode: Code[20]): Boolean;
    procedure ValidateIntegrity(SeriesCode: Code[20]): Boolean;
    procedure GetValidationErrors(): List of [Text];
}
```

## Usage Example

```al
// Example of using validation patterns
codeunit 50903 "Validation Usage Example"
{
    procedure DemonstrateValidation()
    var
        Validator: Codeunit "No Series Validator";
        BatchValidator: Codeunit "Batch No Series Validation";
        ValidationReport: Text;
        SeriesCode: Code[20];
        TestNumber: Code[20];
        ValidationErrors: List of [Text];

    begin

            foreach ErrorText in ValidationErrors do

        end;

        // Validate sequence integrity
        if Validator.ValidateSequence(SeriesCode) then
            Message('Sequence validation passed')
        else begin
            ValidationErrors := Validator.GetValidationErrors();
            foreach ErrorText in ValidationErrors do
                Message('Sequence error: %1', ErrorText);
        end;

        // Run batch validation
        ValidationReport := BatchValidator.GenerateValidationReport();
        Message('Validation Report:\n%1', ValidationReport);

        // Fix common issues
        FixedCount := BatchValidator.FixCommonIssues();
        Message('Fixed %1 series issues automatically', FixedCount);
