Multiple Users need (maintenance) access to a customized table.

Question

Hi Gurus
We created a z table and maintained couple of values in it
The _attributes _ are as follows:
Delivery Class : A (Application table (master and transaction data)
Table Maintenance : Display and Maintenance allowed
ISSUE :
This table does not allow multiple access. In other words, multiple users have to enter this table and change values in this table. Is that possible?
Could you let me know how can this be done?
Thanks a lot

By default, I think SM30, and probably SE16 as well, will lock the entire table if someone is trying to change it.  So, only one person can maintain the table at a time.  This is the simplest way that it can ensure data integrity. 
If I wanted multiple users to be able to maintain a table simultaneously, I'd create a custom screen (dynpro, user dialog, whatever you want to call it) to do it, using lock objects (ENQUEUE and DEQUEUE function modules that you create for the key of your table) to lock / unlock specific rows when a user wanted to change them.  I also might use some sort of reference number generator to ensure unique keys. 
Not a terrifically complicated piece of development but you'd need to get a Abaper to do it.
