I have a form with 3 datasources – CustPackingSlipJour, PurchLine, WHSLoadTable.

I have placed a display method on CustPackingSlipJour form DataSource, but I need access to one field on PurchLine.

All I can access is the CustPackingSlipJour which is passed as a parameter _custPackingSlipJour, as standard.

How can I retreve value from the second DataSource PurchLine?

Answer is simple…You can then use _custPackingSlipJour.joinChild() to retrieve the linked PurchLine, here is an example :

[DataSource]

class CustPackingSlipJour

{



public display real deltaAmount(CustPackingSlipJour _custPackingSlipJour)

{

  real ret;

  PurchLine purchLineLcl;


//This will retreve PurchLine DataSource

  purchLineLcl.data(_custPackingSlipJour.joinChild());



//Here you can use the buffer
  ret = purchLineLcl.LineAmount - _custPackingSlipJour.OTS010_OrPrice;



            return ret;

}

    

}
