Hi Smitha,

By default DT classes allow locking, with obj-browse you can’t acquire lock which eventually avoids saving the data. Use obj-open with lock and  release on commit check boxes checked by supplying keys, once you updated you can use obj-save to save the data.

Remember Obj-save is deferred operation, if you are performing this outside of flow you need to commit explicitly.

  Thank you Satish.

   On the same lines - I do not know the key of the record I need to retrieve . Fox example I need to retrieve a record where say a Flag = "Y" . There may be many records with Flag = "Y" . 

In that case , my understanding is I will need to use Obj-Browse to fetch the key. But at that time the record wont be locked . So another thread or request can update the record . Is there a way to resolve this issue? I want to retrieve a record first based on the flag (which is not the key) and then update the record. 

Thank you .

Thank you for the reply. I was able to do it right.
