SAP Note 322989 - Late block: Number of blocking attempts
Note Language: English Version: 3 Validity: Valid Since 19.10.2000
Summary
Symptom
During the parallel update of goods movements for the same materials, lock
situations occur even if the late block (Transaction OMJI) is activated.
The system generates error message M7023 (plant data blocked by other user)
is issued.
Additional key words
OMJI, lock, late block, M3023.
Cause and prerequisites
"Late block" does not mean "No block". It is required for sending exclusive
blocks. This is carried out online for a short time and then only when
entering the hot phase of the update preparation so that several movements
can be entered at the same time.
This creates situations where a process requests this block, however the
exclusive block is held by another process which is currently in update.
In this case, the waiting process tries several times to request the block
by itself. When a certain number of attempts have been made, it then
abandons this and generates the error message.
Solution
You have the option of varying the number of attempts. As of Release 4.6,
it is possible to do this directly in Transaction OMJI.
In earlier releases, you have to modify the source code. Note 72440 can be
used for identifying the source code points.
The modification requires that you change the number '10' in the lines in
each case
DO 10 TIMES.
This number specifies the number of blocking attempts which are carried out
at intervals of one second.
A small number of attempts causes the error message to be displayed
earlier. A large number increases the number of blocking attempts, however,
it causes the end user to have to watch the hourglass for a long time
before the system nevertheless finally generates the error message again,
as it has not succeeded in accessing the block, despite the long waiting
period.
