Re: [Axapta-Knowledge-Village] Global table methods

[Sonny Wibawa Adi]

Hi Ahmed,
 
 
There are two type of map in axapta. The first is in Data Dictionary | Maps. The second is map class.
For this problem, you should only consider the first one. Data Dictionary | Map is a table definition for the use of mapping ussually two or more tables. For example: In SalesPurchTable Map, there is SalesPurchId field and it is used to map between SalesTable.SalesId and PurchTable.PurchId.
 
If you create a method at SalesPurchTable Map (ex: void test () {}), then you can call from SalesTable table, by using :: operator.
 
SalesTable a;
;
a.SalesPurchTable::test(); //the format is: myTable.myMap::myMethod
 
If you have a method test2 at SalesTable table, then you may call it from SalesPurchTable Map. For this example, we can modifiy SalesPurchTable.test method:
 
void test()
{
    this.test2(); //this will call table method. 
    //warning: Both mapped-table (SalesTable and PurchTable) should have test2 method.
}
 
So, for your problem, you can probably override validateWrite method on the tables and use a map for validating those tables in one place (at the map).
 
at MyMap Map:
public boolean validateWrite(){    boolean ret = false;
    //my validation
    return ret;}
 
at MyTable1 Table and MyTable2 Table:

public boolean validateWrite(){    boolean ret = this.MyMap::validateWrite();
    return ret;}

I think the xRecord system class has methods that are common to all tables but the fact that it is a system method means that you cannot modify it. The only solution I can think of is using a MAP. In this case you will have to manually map all tables to this MAP and then use the required method(s) from the MAP in the mapped tables.
