sumar campos en crytal report

[former_member930467]

Hola, buenos días.

Soy nuevo en este foro y necesito ayuda.

Lo que intento de hacer es un resumen de IVA por tipos.

Tengo estos tres campos en la base de datos

({CABECERAFACCOMPRAS.BASE1})

{CABECERAFACCOMPRAS.TIPOIVA1}

{CABECERAFACCOMPRAS.IVA1}

y esta formula en el repport

{@TIVA1}

en la formula le doy valor del tipo de IVA que quiero buscar, Ejemplo (21,00)

Creo un campo de total acumulado en el cual indico que me sume el campo ({CABECERAFACCOMPRAS.BASE1})

y en evaluar pongo esta formula

if {CABECERAFACCOMPRAS.TIPOIVA1}={@TIVA1} then Sum ({CABECERAFACCOMPRAS.BASE1})

pero no suma nada

Alguien me podria decir como hacerlo ?

The "Evaluating" part of a Running Total tells Crystal when to do the summary and needs to evaluate to either True or False. Try changing the formula to this:

{HEADERFACCOMPRAS.TIPOIVA1-lex.europa.eu = {@TIVA1}

Okay, thank you very much. This works for me

{CABECERAFACCOMPRAS.TIPOIVA1}={@TIVA1}

But I have another ploblema, when one of the fields {CABECERAFACCOMPRAS.TIPOIVA1} is null does not add anything to me.

How can I fix it?

Thank you very much for your help

How are you using the field? If it's in a formula, please post the full formula.

Thanks!

if isNull({#BASE51}) then +0 else +{#BASE51}+

if isNull({#BASE52}) then +0 else +{#BASE52}+

if isNull({#BASE53}) then +0 else +{#BASE53}

You can't chain If statements together like this - Crystal can't process them correctly. Instead, I would do something like this:

NumberVar result := 0;
if not isNull({#BASE51}) result := {#BASE51};
if not isNull({#BASE52}) then result := result + {#BASE52};
if not isNull({#BASE53}) then result := result + {#BASE53};
result

However, it looks like you're using running totals in this formula, which may cause an issue when you try to use this in the Evaluate portion of another running total. You might need to add the following to the top of the formula:

EvaluateAfter({#BASE51});
EvaluateAfter({#BASE52});
EvaluateAfter({#BASE53});

This will ensure that the running totals have been calculated prior to getting the value of this formula.

Muchas gracias por tu ayuda.

esta solucionado con esto que me dices

NumberVar result:=0;ifnot isNull({#BASE51})result:={#BASE51};ifnot isNull({#BASE52})thenresult:=result+{#BASE52};ifnot isNull({#BASE53})thenresult:=result+{#BASE53};result
