# Temporary Table Operation Validation

## Pre-Operation Validation
```al
procedure ValidateTemporaryTableOperation(var TempRecord: Record "Generic Record"; OperationType: Text)
begin
    if not TempRecord.IsTemporary then
        Error('Operation "%1" requires a temporary table to ensure data safety. Current table is permanent.', OperationType);
        
    if TempRecord.IsEmpty() then
        Error('Cannot perform "%1" operation on empty temporary table.', OperationType);
end;
```

## Batch Processing Safety Check
```al
procedure ProcessTemporaryRecords(var TempSalesLine: Record "Sales Line" temporary)
var
    LineCount: Integer;
begin
    // Validate temporary status before bulk operations
    if not TempSalesLine.IsTemporary then
        Error('Batch processing requires temporary table to prevent permanent data corruption.');
        
    TempSalesLine.Reset();
    LineCount := TempSalesLine.Count();
    
    if LineCount = 0 then
        Error('No records found in temporary table for processing.');
        
    if LineCount > 10000 then
        if not Confirm('Processing %1 records may take considerable time. Continue?', false, LineCount) then
            exit;
            
    ProcessBatchRecords(TempSalesLine);
end;
```

## Complex Operation Validation
```al
procedure ExecuteComplexDataOperation(var TempCustomer: Record Customer temporary; var TempVendor: Record Vendor temporary)
begin
    // Validate both tables are temporary
    ValidateAllTablesTemporary(TempCustomer, TempVendor);
    
    // Validate data consistency
    if TempCustomer.IsEmpty() and TempVendor.IsEmpty() then
        Error('At least one temporary table must contain data for processing.');
        
    // Execute complex operation safely
    ProcessCustomerVendorRelationship(TempCustomer, TempVendor);
end;

local procedure ValidateAllTablesTemporary(var TempCustomer: Record Customer temporary; var TempVendor: Record Vendor temporary)
begin
    if not TempCustomer.IsTemporary then
        Error('Customer table must be temporary for this operation.');
        
    if not TempVendor.IsTemporary then
        Error('Vendor table must be temporary for this operation.');
end;
```

## Transaction Safety Validation
```al
procedure SafeTemporaryTableTransaction(var TempGLEntry: Record "G/L Entry" temporary)
begin
    if not TempGLEntry.IsTemporary then
        Error('Financial data operations require temporary tables to prevent accidental posting.');
        
    // Validate data integrity before processing
    ValidateFinancialData(TempGLEntry);
    
    // Process in transaction
    if TempGLEntry.FindSet() then
        repeat
            ProcessGLEntry(TempGLEntry);
        until TempGLEntry.Next() = 0;
end;

local procedure ValidateFinancialData(var TempGLEntry: Record "G/L Entry" temporary)
var
    TotalAmount: Decimal;
begin
    TempGLEntry.CalcSums(Amount);
    TotalAmount := TempGLEntry.Amount;
    
    if Abs(TotalAmount) > 1000000 then
        Error('Total amount %1 exceeds safety threshold for temporary table operations.', TotalAmount);
end;
```
