多开物料帐的解决方法－转

如果在做物料关帐时不小心多做了一两个月的话，可以用TCODE：MMPI初始化过帐期间。如果在做MMPI时系统提示"在初始化之前依照注释
487381的指示"的错误的话，可以用TCODE：SU01中维护用户参数，加参数：MMPI_READ_NOTE，值：YYYYMMDD(如：
20070223)，保存后，再运行MMPI就可以了。
  参见NOTES：487381如下：
Summary
Symptom
For period closing with initialization, the system displays a message
saying that period closing cannot be started.
Before you start period closing with initialization, you must be aware
of the consequences of period closing with initialization.This note
describes the possible data inconsistencies that might occur if you
carry out the initialization in a productive system.The resulting
inconsistencies are not to be traced back to a system error but they
are a result of the period closing program with initialization.
Hence, these inconsistencies can only be corrected within the remote
consulting purchased separately since normally you no longer need to
start the period closing program with initialization in a release >
Rel. 4. 5.

Reason and Prerequisites
The prerequisite up to Release 4.6C is the implementation of Note
369637.
Solution
In order to be able to have the period closing program running, you
must reserve parameter ID MMPI_READ_NOTE with the current date in the
user parameters with the current date in form YYYYMMDD (Y = year, M =
month, D = day).
If you already need this additional security beforehand, implement the
attached correction instructions and create SET/GET parameter
MMPI_READ_NOTE.The SET/GET parameter belongs to development class MG
and should have the following short text:
'Follow the instructions in Note 487381 before initialization '.
In addition, change message MM(016):
'Follow the instructions in Note 487381 before initialization'.
The SAP system works with the period concept of stocks.In the system,
postings are updated precisely to the period.The inventory balances of
the current and of the previous period are relevant to posting.As of
Release 4.5, the history concept of the inventory balances has been
introduced as an enhancement.
Bear in mind that the initialization of a posting period has the
following effects concerning the period stocks:
The initialization of the posting period to a previous or to any
posting period may lead to the loss of the information of the
inventory balances of the previous periods.The book value of the
current posting period is taken as the basis also for values of the
previous period in this case.
          If you want to continue working with this new posting
period, in addition you should execute report Z_DEL_HIST_ENTRIES
attached so that history entries greater or equal to the new posting
period will be deleted.
If you have to briefly reset the posting period by one period (for
example, postings must still be posted in a certain period) just to
make a correction (and for a small number of postings), you should
initialize the posting period back again to the old value so that the
values of the previous period will not be lost (you should forbid
postings when carrying out corrections).
          However, afterwards the values of the previous period or
the history records (as of Release 4.5) of the materials posted in
this case are inaccurate.
          You should NOT execute report Z_DEL_HIST_ENTRIES in this
case.
However, if the posting period is generally reset again to a previous
posting period and if postings were made during this time, all
information on the inventory balance of the previous periods is lost.
          As of Release 4.5a, you should use the cited correction
report Z_DEL_HIST_ENTRIES in order to delete history records that are
more current than the current posting period.Otherwise, it can result
in deviations (inconsistencies) for the update of the history
records.
Important! If there are open physical inventory documents that have
status 'counted' or for which indicator 'Freeze inventory balance' has
been set, you should reject these if they refer to a previous period
or have been created in the former previous period.The inventory
difference to be posted can be determined from the current book value
of the previous period and the book quantity frozen in the physical
inventory document (ISEG-BUCHM) and does not match the inventory
balance of the previous period that is currently valid.
