Error while adding and deleting line items

[Former Member]

Hi all,

I have a Webdynpro application in which Im am trying to update a sales order.

I am using the bapi 'BAPI_SALESORDER_CHANGE'. In my WD application, I am executing the Bapi everytime the user clicks on 'Add' and 'Delete' buttons, after passing the relevant data to the backend. (One line item at a time)

Adding works fine until I delete a line. Once I delete a line item I get an error which says 'Item XXXXX cannot be changed' and after that 'Add' does not work. And this item POSNR displayed in the error message, is not the one I am passing through the WD code.

I am displaying the 'Posnr' values being sent to the Bapi and they are all correct. Im not sure, but seems like some kind of a "cache" problem. The posnr value that the bapi is taking is that of the previous operation.

However, if I run the application freshly, and try deleting the same line item, it gets deleted properly for the first time. Then the problem occurs from the second time onwards.

This is the method for deleting:

input.setL_Salesdocument(wdContext.nodeLi_Sales_Orders().currentLi_Sales_OrdersElement().getSd_Doc());

Bapisdh1X input_headerx = new Bapisdh1X();

input_headerx.setUpdateflag("U");

input.setL_Order_Header_Inx(input_headerx);

wdComponentAPI.getMessageManager().reportSuccess(toString());

Bapisditm item = new Bapisditm();

item.setItm_Number(wdContext.nodeLi_Order_Item().currentLi_Order_ItemElement().getPosnr().toString());

input.addLi_Order_Item_In(item);

Bapisditmx itemx = new Bapisditmx();

itemx.setItm_Number(wdContext.nodeLi_Order_Item().currentLi_Order_ItemElement().getPosnr().toString());

itemx.setUpdateflag("D");

input.addLi_Order_Item_Inx(itemx);

try

{

wdContext.currentZ_Change_Sales_Order_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

}

catch (Exception ex)

{

ex.printStackTrace();

}

and this is for Add

input.setL_Salesdocument(wdContext.nodeLi_Sales_Orders().currentLi_Sales_OrdersElement().getSd_Doc());

Bapisdh1X input_headerx = new Bapisdh1X();

input_headerx.setUpdateflag("U");

input.setL_Order_Header_Inx(input_headerx);

wdComponentAPI.getMessageManager().reportSuccess(posnr+"");

Bapisditm item = new Bapisditm();

item.setItm_Number(<b>posnr</b>+"");

item.setMaterial(wdContext.nodeLi_Order_Item().currentLi_Order_ItemElement().getMatnr());

input.addLi_Order_Item_In(item);

Bapisditmx itemx = new Bapisditmx();

itemx.setItm_Number(<b>posnr</b>+"");

itemx.setUpdateflag("I");

itemx.setMaterial(true);

input.addLi_Order_Item_Inx(itemx);

Bapischdl schdl = new Bapischdl();

schdl.setItm_Number(<b>posnr</b>+"");

schdl.setReq_Qty(wdContext.nodeLi_Order_Item().currentLi_Order_ItemElement().getKwmeng());

input.addLi_Schedule_Lines(schdl);

Bapischdlx schdlx = new Bapischdlx();

schdlx.setItm_Number(<b>posnr</b>+"");

schdlx.setReq_Qty(true);

input.addLi_Schedule_Linesx(schdlx);

try

{

wdContext.currentZ_Change_Sales_Order_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

}

catch (Exception ex)

{

ex.printStackTrace();

}

The posnr (in bold) value is being calculated manually.

Can someone tell me where I am going wrong?

Thanks and Regards,

Hi Reena,

Are you intializing the variable to null and then getting variable value from coresponding context element in each action event.

Like this:

input_headerx = null;

input_headerx = wdContext.nodeList().currentListElement().getHeaderx();

input.setL_Order_Header_Inx(input_headerx);

Hi Suresh,

Thank you for the reply.

I have not done any initialiazation. I tried your code now but without this line :

input_headerx = wdContext.nodeList().currentListElement().getHeaderx();

But got a null pointer exception.

I dont understand what the above line does. I am unable to use it with my code. I trying the following, but there is no completion available.

input_headerx = wdContext.nodeL_Order_Header_Inx.currentL_Order_Header_InxElement.get

Can you please be more specific as to which variable I need to initialize?

Thanks and Regards,

Reena

Hi Reena,

You mentioned in the above that previous value come for second action so i asked whether you intializing the variable and getting the value before going for second action.

Hi Suresh,

You were right. I had not created a new instance of my structure before moving to my second action. So it was using the values initialised in my first action.

Here is my code and it works perfectly now.

public void executesave1( )

wdContext.nodeZ_Change_Sales_Order_Input().bind(input);

input.setL_Salesdocument(wdContext.nodeLi_Sales_Orders().currentLi_Sales_OrdersElement().getSd_Doc());

// Update the Header Details - PONumber and Requested Delivery Date

Bapisdh1 input_header = new Bapisdh1();

input_header.setReq_Date_H(wdContext.currentContextElement().getReq_Del_Date());

input_header.setPurch_No_C(wdContext.currentContextElement().getPO_Number());

input.setL_Order_Header_In(input_header);

Bapisdh1X input_headerx = new Bapisdh1X();

input_headerx.setUpdateflag("U");

input_headerx.setReq_Date_H(true);

input_headerx.setPurch_No_C(true);

input.setL_Order_Header_Inx(input_headerx);

for (int i = deletelist.size()-1 ; i>=0 ; i--)

{

Bapisditm item = new Bapisditm();

item.setItm_Number(deletelist.get(i).toString());

input.addLi_Order_Item_In(item);

Bapisditmx itemx = new Bapisditmx();

itemx.setItm_Number(deletelist.get(i).toString());

itemx.setUpdateflag("D");

input.addLi_Order_Item_Inx(itemx);
