Adding a new Column in Sim Datawarehouse Delivery screen

Question

Hi All,
I need to add one new column 'comments' in Sim Datawarehouse delivery Screen(navigation:Shipping/Receiving->Warehouse Delivery ->select ASN->Select Container) .That column should be mapped with comment_desc colun in rk_shipment_items table
1.created a 'comments' class in src\oracle\retail\sim\shared ,
2.created a 'CommentsDisplayer' in src\oracle\retail\sim\shared\swing\displayer.modified
WarehouseDeliveryCartonDetailPanel.java as-
public List<SimTableAttribute> getAttributes() {
List<SimTableAttribute> attributes = new ArrayList();
attributes.add(new SimTableAttribute("Comments", "comments",true));
          new CommentsDisplayer()));
3.In WarehouseDeliveryLineItemWrapper added the get and set methods for 'comments'
public String getComments() {
return lineItem == null ? null : ((SimpleShipmentLineItem)lineItem).getComments();
public void doSetComment(String quantity) throws BusinessException {
if (lineItem != null) {
     ((SimpleShipmentLineItem)lineItem).doSetComment(quantity);
     //lineItem.setQuantityDamagedBasedOnUOM(quantity);
Now that column is coming on screen and mapped properly with the database column comment_desc
.But that column is coming as disabled on the screen.What else should be done to make that enable?

Answer 1

You first need to add a new column to the definition of the internal table that is passed to the ALV function.  You'll then need to loop through the table and update the new total column.  For example,
LOOP AT itab.
  itab-total = itab-cost + itab-discount.
  MODIFY itab TRANSPORTING total.
ENDLOOP.
You'll need to determine whether discount should be added or subtracted from cost.
The only other change would be to update the field catalog.  There is likely a subroutine in your program that populates the field catalog table with the expected columns in the internal table.  Use the existing code as an example and add another record to the catalog for your total column.
