AOT MAPs in Dynamicis AX with example

mapping different fields with the same EDT from different tables to each other.

Please click here for better example
For example let's that you have an a customer Table and a vendors table and
you want to fill in the fields of a new table from these tables.

If maps did not exist you would have to do this in your new table:

void initFromCustTable(CustTable _custTable)
{
this.AccountNum = _custTable.AccountNum;
this.Name = _custTable.Name;
this.country = _custTable.Country;
this.language = _custTable.Language;
}

AND

void initFromCustTable(VendTable _vendable)
{
this.AccountNum = _vendable.AccountNum;
this.Name = _vendable.Name;
this.country = _vendable.Country;
this.language = _vendable.Language;
}

BUT

if you use a map (mapping newTable, CustTable and Vendor) all you need is
this:

void initFromCustVendMap(CustVendMap _custVendMap)
{
this.AccountNum = _custVendMap.AccountNum;
this.Name = _custVendMap.Name;
this.country = _custVendMap.Country;
this.language = _custVendMap.Language;
}
ONLY once on the map and then you just call the same method with different
buffers:

this.initFromCustVendMap(YourCustTableBuffer);
this.initFromCustVendMap(YOurVendTableBuffer); // NOTE same method but
different buffer.
