How to add the ledger account (ledger dimension ) in form in AX 2012(show the ledger dimension lookup in field)

A ledger account contains the main account, account structure, and each financial dimension value needed to fulfill the related account structure and account rule structures.A foreign key representing a ledger account is a 64 bit integer field that contains the data from the corresponding RecId field the DimensionAttributeValueCombination (LedgerDimension) table.

The ledger account control uses the LedgerDimensionAccountController class as its controller class.  This control handles the entry and display of ledger accounts in AX forms.

In simple scenarios the changes needed on an AX form are as follows:

1.    Verify that the table that holds the Foreign Key to the DimensionAttributeValueCombination table is a data source on the form.

2.    Drag the LedgerDimension field from the data source to the desired location on form design. This creates a SegmentedEntry control with the appropriate DataSource and ReferenceField property values. Alternatively this can be done by adding a SegmentedEntry control to the design and manually setting the DataSource and ReferenceField properties.

3.    Override the following methods on the form.  If the methods already exist just add the code to the methods.  Be sure to denote where the super () call is for the init () method.

classDeclaration():

public class FormRun extends ObjectRun

{

LedgerDimensionAccountController ledgerDimensionAccountController;

}

Init():

public void init()

{

super();

ledgerDimensionAccountController    =LedgerDimensionAccountController::construct(InventParameters_ds, fieldstr(InventParameters,LedgerDimension));

}

Overload the following methods on the SegmentedEntry control instance in the form design

jumpRef():

public void jumpRef()

{

ledgerDimensionAccountController.jumpRef();

}

validate():

public boolean validate()

{

boolean isValid;

isValid = super();

isValid = ledgerDimensionAccountController.validate() && isValid;

return isValid;

}

segmentValueChanged():

public void segmentValueChanged(SegmentValueChangedEventArgs _e)

{

super(_e);

ledgerDimensionAccountController.segmentValueChanged(_e);

}

loadSegments():

public void loadSegments()

{

super();

ledgerDimensionAccountController.parmControl(this);

// The valueof this parameter varies depending on the type of form.

// See the Additional options section for more detail.

ledgerDimensionAccountController.loadSegments();

}

loadAutoCompleteData():

public void loadAutoCompleteData(LoadAutoCompleteDataEventArgs _e)

{

super(_e);

ledgerDimensionAccountController.loadAutoCompleteData(_e)

}

After that go to datasource of form –datasource-field(ledgerdimension)

Overload the below on the data source field that backs the SegmentedEntry control

resolveReference():

public Common resolveReference(FormReferenceControl _formReferenceControl)

{

return ledgerDimensionAccountController.resolveReference();

}
