Overview The DatosComprobacion class manages comprehensive expense verification data for travel assignments. It calculates totals for advance payments (anticipados) and accrued expenses (devengados), tracking verified receipts across multiple expense categories including per diem, fuel, tolls, and passenger fares.
namespace InapescaWeb . Entidades { public class DatosComprobacion { // Financial calculation properties using double precision private double pdTotalComprobado ; private double pdTotalViaticosAnt ; // ... 40+ numeric properties } }
Source: InapescaWeb.Entidades/DatosComprobacion.csThis entity uses double data type for all financial calculations to maintain precision in monetary computations and expense reconciliation.
Constructor and Initialization The constructor initializes all numeric properties to zero:
public DatosComprobacion () { // General totals pdTotalImporteReintegro = 0 ; pdTotalComprobadoTarjeta = 0 ; pdGranTotal = 0 ; // Category totals pdTotalComprobado = 0 ; pdTotalComprobadoViaticos = 0 ; pdTotalComprobadoCombustible = 0 ; // Advance and accrued separately pdTotalComprobadoAnt = 0 ; pdTotalComprobadoDev = 0 ; // ... all properties initialized to 0 }
General Totals Grand Total Properties Grand total of all expenses across all categories and payment types

Usage Example using InapescaWeb . Entidades ; // Create expense verification record var datos = new DatosComprobacion (); // Advance payment verification datos . DiasAnt = 5 ; datos . TotalViaticosAnt = 5000.00 ; datos . TotalCombustibleAnt = 1500.00 ; datos . TotalPasajeAnt = 2800.00 ; datos . TotalTotalAnt = 9300.00 ; // Verified expenses from advance datos . TotalComprobadoViaticosAnt = 4850.00 ; datos . TotalComprobadoCombustibleAnt = 1480.00 ; datos . TotalComprobadoPasajeAnt = 2800.00 ; datos . TotalComprobadoAnt = 9130.00 ; // Accrued expenses (additional days) datos . DiasDev = 2 ; datos . TotalViaticosDev = 2000.00 ; datos . TotalCombustibleDev = 600.00 ; datos . TotalTotalDev = 2600.00 ; // Verified accrued expenses datos . TotalComprobadoViaticosDev = 1950.00 ; datos . TotalComprobadoCombustibleDev = 580.00 ; datos . TotalComprobadoDev = 2530.00 ; // Calculate grand totals datos . TotalComprobado = datos . TotalComprobadoAnt + datos . TotalComprobadoDev ; datos . GranTotal = datos . TotalTotalAnt + datos . TotalTotalDev ; // Calculate reimbursement // (Total allocated - Total verified) double totalAllocated = datos . TotalTotalAnt + datos . TotalTotalDev ; double totalVerified = datos . TotalComprobado ; datos . TotalImporteReintegro = totalAllocated - totalVerified ; // If negative, employee should return funds // If positive, additional reimbursement to employee Console . WriteLine ( $"Total Allocated: $ { totalAllocated : N2 } " ); Console . WriteLine ( $"Total Verified: $ { totalVerified : N2 } " ); Console . WriteLine ( $"Reimbursement: $ { datos . TotalImporteReintegro : N2 } " );
Calculation Patterns Category Totals // Total verified expenses = sum of all categories TotalComprobado = TotalComprobadoViaticos + TotalComprobadoCombustible + TotalComprobadoPasaje + TotalComprobadoPeaje ;
Advance vs Accrued // Separate verification for advance and accrued TotalComprobadoAnt = TotalComprobadoViaticosAnt + TotalComprobadoCombustibleAnt + TotalComprobadoPasajeAnt + TotalComprobadoPeajeAnt ; TotalComprobadoDev = TotalComprobadoViaticosDev + TotalComprobadoCombustibleDev + TotalComprobadoPasajeDev + TotalComprobadoPeajeDev ;
Reimbursement Calculation // If verified < allocated: employee returns money // If verified > allocated: institution pays employee TotalImporteReintegro = ( TotalTotalAnt + TotalTotalDev ) - ( TotalComprobadoAnt + TotalComprobadoDev );
Business Rules Validation should be implemented in the business logic layer, not in the entity itself.
Non-Fiscal Receipt Limits if ( TotalComprobadoNoFiscal > MaxNofiscalAnt + MaxNofiscalDev ) { // Exceeds maximum allowed non-fiscal receipts // Reject or require additional fiscal invoices }
Category Verification // Verified amounts should not exceed allocated amounts if ( TotalComprobadoViaticosAnt > TotalViaticosAnt ) { // Per diem verification exceeds advance allocation // Possible data entry error }
Per Diem Rate Validation // Verify daily rate matches zone classification double dailyRate = TotalViaticosAnt / DiasAnt ; // Compare against official rate tables
CFDI Integration Mexican tax regulations require CFDI (Comprobante Fiscal Digital por Internet) for expense verification. The system processes CFDI XML files to extract and validate expense data.
