Locking mechanism for web dynpro ALV list

Hi Experts,

I want to provide locking mechanism to my ALV list...

Currently my application is having a ALV list.

Consider there are 10 records in the ALV list.

If the user selects 1,3 and 5 records in the ALV list some columns of that record will be in edit mode. At this point of time user will edit the records and save it.

When a user editing another user should not have an access to these records if the second user want to edit locking mechanism should come into the picture.

I am done with the editing certain columns and i am not aware of the best locking approach?

    Hi Venkat,

    If you have an action that sets the columns to editable when the user selects the rows, in that same action you can call the appropriate ENQUEUE_* function module to lock the objects behind the selected rows.

    You'll need to identify what the appropriate ENQUEUE_* function is based on what table(s) you will update upon save of the changes. One way to identify the appropriate lock object is to do a where-used on the table(s) that will be updated and look for Lock Objects.

    Remember to call the corresponding DEQUEUE_* function module to release the locks after saving.
