enque/delay_jitter is a SAP Parameter attribute which is used to control Offset for enqueue/wait operations information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
If lock operations are repeated, the wait time (by default, 1 second) is
reduced or increased by a random offset to avoid deadlocks due to
synchronization.
This parameter defines the maximum offset in milliseconds. The wait time
between two attempts for the lock operation is then in the period [wait
time - offset, wait time + offset]. With the default setting of 400 ms,
this is between 0.6 and 1.4 seconds.
See SAP Parameter Documentation for full SAP documentation for this profile parameter.
