Generating Indiex for dynamically added table rows  in HRFORMS

Hi ,
We are developing Payslip  in HRFORMS by copying standard form.
We have got one business scenario which requires a table rows needs to generated dynamically to populate the retro values in the form.
We could able to generate the table rows dynamically by below command in HRFORMs scripts.
Table1.Row.InstanceManager.addInstance(1) but it is not generating with correct index.
Please help in adding table rows dynamically at specified index.
Regards,
akula

You can do that with 2 differents ways :
by creating a colomn key which is the concatenation of the key for each lin
by using field groups
I think you have to use the second one.
[sample by help|http://help.sap.com/saphelp_nw70/helpdata/en/ce/b518b6513611d194a50000e8353423/frameset.htm]
In this case you can put dynamiquely what are you wanted in your keys.

    Hi,
    If you really want to have a dynamic table, then you will have to find a way to generate a whole new table, and then copy the data from the old table to the new one. There is no way to modify a type during runtime in ABAP.
    Here an example how to generate a dynamic table based on another internal table, hope this will help you.

    Hi,
    Thanks for your reply.
    Ya. I'm adding rows in a table dynamically which is grouped in a subform which is flowable and the buttons are placed in the same subform. At the end of the row I'm having the hidden fields.
    So what I want is without focusing the tab on hidden field I want to traverse the first field of the next dynamic row. For that I have used the access property as protected on hidden field, but its not working properly.
    Please help me on this ASAP.

    Hi
    How to make the cell of a tablerow editable based on flag in backing list object bound to row? I can't decide the editable property while creating table columns. So i can't use setCellFactory() during creation. However setCellFactory() makes all cells in table column editable.How to make non-editable table row cell editable and vice-versa based on flag?

    hi
    good
    if you want to create two different view for a same table than you cant give the same name for the same view,otherwise it would allow you to create the view.Try out with different view name as well as the function group name,i hope this ll work.

  • To create a deep structure for dynamic internal table.

    Hello
    My ALV has fields which are defined dynamically during execution.
    so, i did it in the following way,

    in the output internal table <t_dyntable> to meet our requirement.
    My issue is about declaring one such field of type 'h' in this dynamically created internal table ''<t_dyntable>".
    I tried in the following way by adding one such field to fieldcatalog :
    *Field for Styling
      ADD 1 TO v_counter.
      wa_fieldcatalog-fieldname   = 'TS_STYLEROW'.
      wa_fieldcatalog-tabname     = 'TS_STYLE'.
      wa_fieldcatalog-col_pos     = v_counter.
      wa_fieldcatalog-no_out      = 'X'.
      wa_fieldcatalog-inttype     = 'h'.      " I even mentioned this
      APPEND wa_fieldcatalog TO ts_fieldcatalog.
      CLEAR  wa_fieldcatalog.
    But this is creating a field of type 'C' in the table <t_dyntable> instead of what i was expecting
    Guyz and respected,
    Please advice me with the solution or ur ideas....
    Note : The overall requirement is create a deep structure for dynamically generated internal table.

  • Validation for transient VO/table rows

    Hi,
    I have 2 pages:
    1. First page is an entry page with an editable table like this (It's backed by a transient VO which I initialize with some blank lines.) and a submit button:
    Part Type (dropdown)          Part num (text box)          Quantity (text box)     
    2. Second page is a read only table that shows results from the same transient VO with additional info.
    Part Type          Part num          quantity     price
    When hitting the submit button on the first page, I'd like to run a custom validator that validates each row in the entry page table.
    Since it's a transient VO and has no entity object, I didn't know how to do it in the model. The validation should use the part type and part code values and call a database API to do tha validation, and then display the message from the API in the part code text box.
    I got it to (sort of) work using a validator method in a backing bean.
    This is how I implemented the part validation (on first page).
         - Make part type autosubmit = true.
         - Make the editable table bind to the backing bean - it basically has a getTable1() and setTable1 method.
         - Add validator to Part num column.
         - In the validator code in the backing bean, use
              it3_validator(FacesContext facesContext,
                                  UIComponent uIComponent, Object object)
                 FacesCtrlHierNodeBinding q = (FacesCtrlHierNodeBinding)this.getTable1().getRowData();
                 Row currentRow  = q.getRow();
              OperationBinding method = getBindings().getOperationBinding("validateItem");  //call database api in AM
                     method.getParamsMap().put("item_number_in",(String)object);
                 method.getParamsMap().put("item_type_in",(String)currentRow.getAttribute("PartType"));
              map = (HashMap)method.execute();
                 if (map.get("valid_item")!= null && map.get("valid_item").toString().compareToIgnoreCase("Y") != 0)
                          String msgS = (String)map.get("error_msg");
                          FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR, msgS, msgS);
                          facesContext.addMessage(uIComponent.getClientId(facesContext), message);
                          ((RichInputText)uIComponent).setValid(false);                        
         It works, but once a part no in a row becomes invalid it doesn't recognize changes in the part type in that row. How can I set it so that when I change part type, the validation recognizes that I've change the part type? So if I enter a correct part num but wrong pary type, and then change part type to correct value, it should not throw error message again.
    Should I even be doing this in the backing bean? Is there some way I can just implement it in the model so I don't have to worry about getting row level info from getTable1?
    I'd posted on this before, but the solution I tried didn't really work at all (the implementing-custom-generic-plsql uses entity object to execute the db api)
    Re: Validation using a DB function
    I'm using JDev 11.1.1.2.0
    thanks,
    Kalp

    Thank you Timo that helps me understand the validation behavior..
    I added this in the AM and it'scalling the validation:
            Row[] rows = vo.getAllRowsInRange();
            for (Row row : rows)
                row.validate();
            }and I added more code to the validation:
        @Override
        public void validate(){
            System.out.println("Validate in transient vo");
            System.out.println("getPartType from rowimpl:"+getPartType());
            System.out.println("getPartCode from rowimpl:"+getPartCode());       
            HashMap map = new HashMap();
            map = validateItem(getPartCode().toString(),getPartType().toString());
            if (map.get("valid_item")!= null && map.get("valid_item").toString().compareToIgnoreCase("Y") != 0)
                throw new JboException(map.get("error_msg").toString());
            super.validate();
        }   The message then appears as a popup which shows the error message for the first invalid row and also doesnt stop the navigation to next page.
    So I changed to:
       @Override
        public void validate(){
            System.out.println("Validate in transient vo");
            System.out.println("getPartType from rowimpl:"+getPartType());
            System.out.println("getPartCode from rowimpl:"+getPartCode());       
            HashMap map = new HashMap();
            map = validateItem(getPartCode().toString(),getPartType().toString());
            if (map.get("valid_item")!= null && map.get("valid_item").toString().compareToIgnoreCase("Y") != 0)
                FacesContext fctx = FacesContext.getCurrentInstance();
                String msgS = (String)map.get("error_msg");
                FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR, msgS, msgS);
                fctx.addMessage(null, message);
            super.validate();
        }   This is better, but still I don't know how to tie the error message to a UI component. This shows the list of validation messages in the popup but I want to tie the corresponding error message to the part code for the invalid row in the editable table UI.
    I want it to have the same look/feel/behavior as when I add something like a Compare validator on an attribute in the VO. If I add a validator like Compare to 10, then the message is tied to the specific cell
    in the UI table and it stops navigation.
    How can I mimic this "seeded" type of behavior?
    Thanks for your help on this!
    thanks,

    I want to pivot data werks and to display in webdynpro alv.
    Thnx:

    You can use the RTTI to build up a dynamic structure in memory:
    Something like this - where both the data and its structure and meta data all come from an external source (which happens to be MDM in this case):

  • At end of field,  for dynamic internal table entries ?

    Dear All,
    I've data in my dynamic internal table.
    But, to understand in a better way I created a test program with static entries.

    APPEND itab.
    CLEAR itab.
    itab-name = 'AAAD'.

    APPEND itab.
    CLEAR itab.
    itab-name = 'BBBA'.
    itab-year = '2007'.
    APPEND itab.
    CLEAR itab.

    Now for the above program the Output is :
    Name     Year          Count
    ********** 2005          5
    ********** 2006          6
    ********** 2007          4
    ********** 2008          4
    " Forget about the asterisk values as it's an example !
    The above output is correct, But in my real case the table structure is not like the above .
    The order of the field are in reverse.
    i.e. The internal table is like this :
    Case 2 -->
    DATA: BEGIN OF itab OCCURS 0,
            name TYPE char10,
            year TYPE char4,
          END OF itab.
    DATA: BEGIN OF itab2 OCCURS 0 ,
            name TYPE char10,
            year TYPE char4,
            count TYPE i,
          END OF itab2.
    In this case if I'm using at end of year the output is coming wrong.
    Even on change of is also not working.
    Request you guys to help me out so that I can achieve the same output as of case 1 with the table declaration as of CASE 2.

    Here, <FS_1> is the field symbol of table type and it holds all my data. and LT_FIELDCATALOG2  is the structure of my fieldcatalog
    Thanks and Regards,

    Hi Avinash,
    Either use parameter
    I_STRUCTURE_NAME = W_TABNAME
    or
    IT_FIELDCATALOG = LT_FIELDCATALOG2
    Both are not required.
    At the end of ur program simply use a write statement like below. Your program will work.
    IF SY-SUBRC 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    Write /.      <----
    Thanks,

  • Dynamically adding a row in a table in JSF

    Hi All,
    I am searching for a control in JSF using which I can dynamically add more than one row in a table. Currently I am handling this in javasript where I have to click on the "Add Row" button to add one more row at the bottom of the table. I want to get rid of javascript.
    If anyone knows about such control then please help me.
