Hi guys,

I'm trying to make use of class called "TaxRegulation"

TaxRegulationDetail taxRegulationDetail = TaxRegulation::newTaxRegulation(salesTotals.tax());

TmpTaxRegulation    tmpTaxRegulationDetail = taxRegulationDetail.tmpTaxRegulationDetail();

but currently hit error like this :

The error as in the picture is hit on the 1sts line, may I know how to resolve this ?

The intention is to get TaxRegulation data based on sales line.

Thanks,

Here you have created the class object but you are calling a different class. It should be like,

ClassName classObj = ClassName::method name(param1);

Similarly for second line also. But can you tell us why you are calling another class here?

Hi Bharani,

Yes, sorry, I realized this just now, then I'm changing it to this :

TaxRegulation taxRegulation = TaxRegulation::newTaxRegulation(salesTotals.tax()); TaxRegulationDetail taxRegulationDetail = taxRegulation as TaxRegulationDetail; TmpTaxRegulation tmpTaxRegulationDetail = taxRegulationDetail.tmpTaxRegulationDetail();

But it looks it is not the correct way either, since I then have error on the 3rd line

Can you help me to understand the error and how to use it correctly ?

The TaxRegulationDetail is an extend class of TaxRegulation.

Thanks,

Your code seems to be correct. This error comes when the object does not have any value. Can you check if salesTotals have a buffer and also in the tax regulation?

Hi,

The SalesTotal have a buffer as well as TaxRegulation.

As in this screenshot :

But I think the "taxRegulationDetail" is not correct/working as it is still null.

I tried to take a look at class TaxRegulationDetail, and the remarks says it "manages tax adjustments at the invoice line detail level", does it means this class only handle data at Invoice level ?

As my process, Sales Order, is not invoiced yet.

For the class TaxRegulation itself actually also have method "taxRegulationDetail" but it is set to Null ->

How to get data per Sales Line exactly ?

Thanks,

This is solved. After learning the class TaxRegulation already can handle the selection for TaxRegulationDetail based on AR - Parameters, Ledger & sales tax -> Enable tax adjustment in detailed mode.

When it is selected, TaxRegulation will be cast as TaxRegulationDetail.

Thanks,
