Hi,

i would suggest:

- read your column in the action of the save button, if it is inital

- if initial enable the field.

     you can do this by binding the attribute enable to a boolean in the context and change value of this boolean in the context or change it direct in the attributes of the UI element.

Hi Karthik,

when you click the save Button, the action assigned to this button is executed. In this coding you have to check if your column is filled.

If the column is not filled change attributes of the ui filed to enable it.

Sorry, maybe you cann specify the problem? Is it the coding in the action to check if column is initial or is it changing of the attributes?

Please check the document provided by Rama, it gives you a goof example on what to do.

regards

Hi Alex,

Thanks for your reply .

I have used the below sort of code inside the loop Statement of SAVE method ..Still, I could able to see the field in disable mode but not in Enable mode ...

        IF lv_attr_name = 'DAY1' OR lv_attr_name = 'DAY2' OR lv_attr_name = 'DAY3' OR lv_attr_name = 'DAY4' OR
         lv_attr_name = 'DAY5' OR lv_attr_name = 'DAY6' OR lv_attr_name = 'DAY7' .

        lo_el_timesheet->set_attribute_property(
        EXPORTING
          attribute_name = lv_attr_name
          property       = if_wd_context_element=>e_property-enabled
          value          = abap_true  ).
      ELSE.
        lo_el_timesheet->set_attribute_property(
EXPORTING
  attribute_name = lv_attr_name
  property       = if_wd_context_element=>e_property-read_only
  value          = abap_false  ).
      ENDIF.

Can u suggest an idea on it .

Hi Karthik,

Create one new attribute to control the read only(with type wdy_boolean) and bind it with the required field's read only property , post save action you can call one more method there check the initiality of the required fields , if those are initial make the fields are editable.

Hi Karthik,

i have created a table and a button in the screen , inside the table's node have created one more attribute called 'R1(type wdy_boolean)' to control the read only property and binded the same R1 with all table fields read only property.

and in the submit button click i am calling this code to enable the fields:

  DATA lo_nd_vbap TYPE REF TO if_wd_context_node.

  DATA lo_el_vbap TYPE REF TO if_wd_context_element.

  DATA ls_vbap    TYPE wd_this->element_vbap.

  DATA lt_vbap    TYPE wd_this->elements_vbap.

  lo_nd_vbap = wd_context->get_child_node( name = wd_this->wdctx_vbap ).

  lo_el_vbap = lo_nd_vbap->get_element(  ).

  lo_nd_vbap->get_static_attributes_table(

  IMPORTING

  table = lt_vbap ).

  CLEAR ls_vbap.

  LOOP AT lt_vbap INTO ls_vbap.

    MOVE ' ' TO ls_vbap-r1.

    MODIFY lt_vbap

      FROM ls_vbap

     TRANSPORTING r1.

ENDLOOP.

  lo_nd_vbap->bind_table( lt_vbap ).\

and this will enable the read only input fields into editable fields.

Hi Karthik,

Can you please check the cell variant which is created inside the table cell , if that is not required you can remove that and check.

Hi Karthik,

You need to use the READ ONLY property of context attributes in your case.

If there is empty value, set the value read_only to FALSE.

Please refer my document below , Hope it suits your requirement

In the above document, i used lock and unlock buttons, you can use logic of unlock for SAVE action as your requirement.

Rama
