Updating One Field from Another. Easy Customization.

Hi Everyone.

One of the most often called customization requests is to default (or update) a Field A, based on what was entered in a Field B. And now its time for me to post a memo article on standard technique for this customization.

Lets define a scope of work:

1. When we issue an invoice to a customer.
2. And then select a Project used by this customer.
3. We have to default a Customer Ref Number field with a Project Purchase Order Number.
4. Which is, in its own case, an Attribute of a Project, and has to be retrieved from there.
5. PO Number is defined in Project Module "Attributes" screen and entered into a "Project" Maintenance screen.

Something like this:



In the video below I comment on customization done. Please find the code for the customization below.



Here is the code:

using System;
using System.Collections;
using System.Collections.Generic;
using PX.Data;
using PX.Objects.GL;
using PX.Objects.CM;
using PX.Objects.CS;
using PX.Objects.CR;
using PX.Objects.TX;
using PX.Objects.IN;
using PX.Objects.BQLConstants;
using PX.Objects.EP;
using PX.TM;
using SOInvoice PX.Objects.SO.SOInvoice;
using SOInvoiceEntry PX.Objects.SO.SOInvoiceEntry;
using PX.Objects.SO;
using PX.Objects.DR;
using PX.Objects;
using PX.Objects.AR;
using PX.Objects.PM;

namespace PX.Objects.AR
{
  [PXCustomization]
  public class Cst_ARInvoiceEntryARInvoiceEntry
  {

    #region Event Handlers
protected override void ARInvoice_ProjectID_FieldUpdated(PXCache senderPXFieldUpdatedEventArgs e)
{
  base.ARInvoice_ProjectID_FieldUpdated(sendere);
  var row (ARInvoice)e.Row;
  var ProjectID row.ProjectID;
  var CustRefNbr row.InvoiceNbr;
  string EntityType "PR";
  string Attribute "PONUMBER";
  //CustRefNbr = CustRefNbr + 1;
     
  PMProject pm PXSelect<PMProject,
             Where<PMProject.baseTypeEqual<PMProject.ProjectBaseType>And<PMProject.nonProjectEqual<False>And<PMProject.contractIDEqual<Current<ARInvoice.projectID>>And<PMProject.isTemplateNotEqual<True>>>>>>.SelectSingleBound(thisnew object [e.Row });
  
  if (pm != null)
  {
  //CustRefNbr = pm.ContractCD;

  PXResultset<CSAnswersres PXSelectJoin<CSAnswers,
       InnerJoin<CSAttributeOn<CSAttribute.attributeIDEqual<CSAnswers.attributeID>>>,
       Where<CSAnswers.entityTypeEqual<Required<CSAnswers.entityType>>,
       And<CSAnswers.attributeIDEqual<Required<CSAnswers.attributeID>>,
       And<CSAnswers.entityIDEqual<Required<CSAnswers.entityID>>>>>>.Select(thisEntityTypeAttributepm.ContractID);
  
  CSAnswers ans res;

  if (ans.Value != null)
  {
    
  //CustRefNbr = ans.Value;

  ARInvoice line sender.CreateCopy(rowas ARInvoice;
  line.InvoiceNbr ans.Value;
  sender.Update(line);
  //string msg = CustRefNbr;
  //throw new PXSetPropertyException(msg);
  //row.InvoiceNbr = CustRefNbr;
}}}


    #endregion

  }


}

All the best,
Sergey.

  1. Sergey, can you talk about accessing and modifying attribute fields in general? There is a serious lack of that information in Acumatica. For instance accessing and modifying attributes in Stock Items.

    1. Hi, thanks for asking. Just found a learning video on adding attributes. https://youtu.be/igpoOIUJ1hU But I believe you need something more comprehensive, like where they stored and how to access them?
