Issue when catching the changes made in ALV

[Former Member]

I have the ff requirements.

• I have main tabs - X and Y.
• Under tab Y, I have 4 tabs - A, B, C, D.
• I have problem with tab B.
  • This tab has an ALV table with 1 editable column.
  • This column is of type char80.
  • When I change the value on that column, I expect that when I click somewhere on my screen (say I navigate to other tabs), the data will be stored in the context. Now, when I try to catch my changes in WDDOBEFOREACTION, the old value is reflected. The new value that I entered wasn't caught.
  • I also notice that when I 'enter' after making my changes in the column, that's the time that my changes got caught in the context.
  • I tried to observed the data when it passed through WDDOBEFOREACTION, WDDOAFTERACTION, WDDOMODIFYVIEW after clicking 'enter', but at those moments the changes that I made were still not caught yet in the context.
  • Are there other methods that could have possibly caught the changes?

Please advise how and where to catch the changes I made in the ALV.

Thank you so much.

Hi Kranthi,

It doesn't work.

I tried to catch the changes of the ALV table.

Instead, it reflects the changes of the tab.

DATA: L_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
L_NODE = WD_CONTEXT->GET_CHILD_NODE( 'MY_ALV' ).
L_NODE->BIND_TABLE( L_CHANGES ).

I was expecting, that it will show the changes of 'MY_ALV', but it doesn't.

The old_value and new_value reflects that tabs that I clicked, not that of the ALV.

Hi Navi,

Create an attribute in the component controller and set the data ( which you are displaying in the ALV table ) on the load of the page or when your displaying data in the table.

for eg: before navigation if you need to check, is there any changes, then you can check here. If required you can stop navigation

Thanks & Regards,

Hi Sankar,

The issue is, the changes doesn't get reflected right away.

If I change the table entries and click another tab, the changes won't isn't stored in the context.

It get's stored only if I click 'check' or hit enter.

The user need not do those extra actions in order to catch the changes.

Thanks.
