Dear,
You can read it from the config guide :
Exclusive block during goods movements
Definition
When material master data is read for the first time during a goods
movement, this indicator specifies that tables MARC (plant data) and
MBEW (accounting data) are locked exclusively until the goods movement
has been fully posted.
Another user cannot maintain the material during this time. This ensure
that the goods movement is valuated correctly and that the stock
quantities and values are updated correctly. The disadvantage is the
long period of time for which the lock is set (from the time the
material master data is first read when the goods movement is entered
through to completion of the update posting).
Late block for goods movements
Definition
Specifies that a material:
o is not always blocked exclusively, but only if data is actually to
be saved.
o is blocked exclusively as late as possible to keep the lock time t
a minimum.
The advantage is that several users can enter goods movements at the
same time because only one shared lock is set for the material when th
movement is entered.
The disadvantage is that the material master record is read several
times and, in the case of an outward stock movement, that the lock
entries of other users on the ATP server also have to be considered.
These additional accesses have a negative effect on performance.
