Reading bsp-variable data in iterator

Hi,

I'm a junior developer and currently have a problem I can't solve....

I also couldn't find a solution by searching the forums here.

The situation so far:

I have a tableview in a bsp site.

Now I have to implement a functionality to insert new data to the database using

a new empty row in the tableview and saving that after several checks.

That works so far....

but, the problem is, that this should also work for filtered tableviews...

So I catch the filtervalues via the method get_row_filter_value and insert them in the

empty row - so it's visible even if the table is filtered.

I also implemented that.

Now the issue I can't solve is that when modifying a selected row,

not every field should be editable for the user.

But a new empty row should be editable in more fields.

I use the IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START

to check for empty fields and make them editable if they are,

assuming that this is a new row that should be editable then.

But, if I have to bypass the tableview filter, and insert the filtervalue by default,

the row isn't empty any more, and the fields won't be set editable.

I wanted to use a page attribute to mark a creation_mode,

but I can't access it in the iterator??

How can I achieve to get values of variables of the bsp in the iterator??

Hope you can help me somehow and understand my issue...

thx

Hi Marcus,

Welcome to SDN!

You can use the constructor method of your iterator to pass any ABAP variable to you iterator. For example, let's assume you have a page attribute called F_CREATION in your BSP page. When creating your iterator instance, use the following:

<%
DATA: lo_iter TYPE REF TO z_your_iterator_class_name.
CREATE OBJECT lo_iter
  EXPORTING
    vi_creation = me->f_creation.
%>

In your Iterator class, create an instance attribute called m_creation, and a constructor method with importing parameter vi_creation. In this constructor, put the following code:

me->m_creation = vi_creation.

Now the iterator attribute m_creation is available in render_cell_start method, and has the same value as the BSP F_CREATION attribute when the iterator is created.

Regards,

Tanguy
