Hi,

Follow the below steps which will help to resolve your issue.

1)As you are doing validation on click of Upload button and checking of the date in rows are valid or not.

2)

IF ( LV_DATE is not valid).

     "show the error message & set the attribute which you have binded to the visiblity property

      of button to ABAP_FALSE(here button will be disabled)

data : lo_element type ref to if_wd_context_element.

       lo_element = wd_context->get_element( ).

      CHECK lo_element is not initial.

     lo_element->set_attribute(
     exporting
     value    = 'ABAP_FALSE'
      name  = '<ATTRIBUTE_NAME>'.

        RETURN.

ELSE.

     lo_element->set_attribute(

     exporting

     value    = 'ABAP_TRUE'

      name  = '<ATTRIBUTE_NAME>'.

    "Proceed further as per your requirement.

ENDIF.

Below is the code for your reference only.

Hope this helps you.

Hi,

Do the below logic.

1. Bind the visibility property of your Save button to a context of type WDUI_VISIBILITY and make the default value as '01'.

2. So when ever your application starts, user can't see the 'Save' button at any time.

3. Now when the data is uploaded and found that there is no error, make the 'Save' button to visible    by make the context value as '02'

    lref_context->set_attribute(

     name  =  `FIELDS_VISIBLE`

     value = '02' ).

Hope you got it:)

BR,
