How to make rows editable of a dynamic ALV

Hi All,
I'm displaying a dynamic internal table on an ALV.
The probelm is that some of the rows of that ALV should be editable.
I checked some of the forums, where I got a clue that I have to update this LVC_S_STYL structure for this requirement.
I populated this structure also. But still that ALV is coming as non-editable.
Kindly help me out in resolving this issue.
Thanks and Regards,
Abhijeet

How to make Rows editable in ALV

Hello,
I show some Records in my ALV and Column PersonalNumber is noneditable.
and I have created Append Row Button. If I click on this Button, then new added PersonalNumber should
be editable and old PersonalNumbers should be noneditable. How can we realize that?
otherwise; How can we make some editable and some noneditable in ALV?
Thanks!
with my Best Regards

DATA: LR_COLUMN_SETTINGS TYPE REF TO IF_SALV_WD_COLUMN_SETTINGS,
LR_INPUT_FIELD TYPE REF TO CL_SALV_WD_UIE_INPUT_FIELD.
LR_COLUMN_SETTINGS ?= L_VALUE.
LR_COLUMN = LR_COLUMN_SETTINGS->GET_COLUMN( 'Your Field' ).
CREATE OBJECT LR_INPUT_FIELD EXPORTING VALUE_FIELDNAME = 'Your Field'.
LR_COLUMN->SET_CELL_EDITOR( LR_INPUT_FIELD ).
If any doubts let me know.

Hi,
the tree component has changed compared to 10.1.3. You no longer have a tableSelectmany component that renders as checkboxes. Instead you use the ctrl key and select the table rows

How to make field editable in Tcode WPED

Hi,

For Inbound IDOCS coming from POS to SAP System, IDOCs which are in unprocessed category in WPER Tcode.
Now problem is in Tcode WPED there is a transaction date field which is now non editable in ECC6.0
I want to make it modifiable.
Earlier in ECC5.0 It was editable.
So how to make that field modifiable.
Regards,
Divya

Thanks Chenna
But that field is sometimes coming editable and sometimes not.....may be it depends on some condition.....but I want to make it editable always whenever an Inbound IDOC is in "To be processed" status in WPER tcode.
Iam going in that screen where field is coming uneditable is:
Tcode WPER -
> Inbound IDOC processing---> to be processed idocs---> double clicking on Idoc Number (comes on WPED screen with non-editable fields in overview table).
If I'm double clicking on that transaction date field it goes to the screen whcih shows Sales Audit Editor: Item list of aggregate sales.
Suggest me how to make it editable.

How to make row number in local member dynamic

I have create multiple local member and the formula I the local member is such as
=SUM(row11+row14+row16)
then I add another couple of row before row 11, now the formula should be:
=SUM(row13+row16+row18)
anybody know is there a way how to make the formula in the local member dynamic, which means that if I add rows of drop rows, the formula in local member will automatically change?

Hi Jian,
You can create local my by "Activate Local Member Recognition", but make sure "Use Position in axis" should be unchecked.
Also make sure you have added all required Local members before any insertion of rows.
Hope this should work.
Thanks,

Hello
The ALV tree control is not intended for making values editable (e.g. see
[How to make ALV tree columns editable|http://sap.ittoolbox.com/groups/technical-functional/sap-abap/how-to-make-alv-tree-columns-editable-2052414])
However, if you need an editable tree control then you have to use a different class (e.g. CL_ITEM_TREE_MODEL or CL_COLUMN_TREE_MODEL) but you will not have the ALV functionality of the ALV tree control.

How to make create, edit, display form in a page fragment ?

Hello everyone,
I have a problem when I want to make create, edit,display in a page.
Ok let's say we have created two pages,
In page A we have 3 buttons, CreateEmp, EditEmp and DisplayEmp button and one text field as a parameter field to edit and display (let say employeeId).
In page B we have form employee to create new employee, edit employee and display and a button AddMoreEmp (to add more employee without back to page A)
in this case if button EditEmp is pressed in page A, so button AddMoreEmp in page B will be enabled
if button DisplayEmp in page A is pressed , so button AddMoreEmp in page B will be disabled.
Thanks in advance,
samantha

I think what you are looking for is a comb field. It acts like a regular field but puts the vertical lines in between each character. You can turn the comb on in the object palette and indicate how many chars will appear in the field (so that it knows how many lines to draw).
