Object Locked by User (same as mine)

Hi,

I have a Z program which changes the Payment Plan of a customer and produces an interim invoice.

While executing it, at a certain point, it gives an error message " POD (Point of delivery) XXXXX locked by User <same as mine>".

I checked and found no other sessions which was locking the object.

May be this is due to some part of the code in the Z Program but funnily i am not even concerned with the POD factor in the program.

Can anyone give me a startup to the remedy by letting me know if really the POD has been locked.

Do I have an option of checking on the locked objects under my user-name while debugging the program so that i can zero in on the area causing the lock.

Please suggest.

Thanks,

Arindam.
