Hi,
I have a dialog program callable by a transaction. In this program there are
many tab strips with a database table for each tab strip. You can see, change
and delete the data of the database tables on each tab strip.
Now it should be possible, that only one user can change and delete data at
the same time. So I have thought about writing a value in the memory and read
it every time at the beginning of the program.
If one user is starting the program and there isn´t an entry in the memory, the
memory should be set now. If another user is starting the program now, there
should be an entry in the memory, that I can protect the tables for changing and
deleting.
I tried it like that:
DATA: user TYPE sy-uname.
IMPORT user FROM MEMORY ID 'user'.
IF user IS INITIAL.
user = sy-uname.
EXPORT user TO MEMORY ID 'user'.
CLEAR user.
ENDIF.
It is working, if You call the transaction at once. The username is stored in the
memory.
But when I now start the transaction in another mode the same time, I´m not
getting any entry for the field 'user' in the memory.
Any ideas? Or do You have any better ways how to protect the data?
Thank You very much!
