Reason and Prerequisites
Incorrect receipt values and issue values in info structure
S031.
Solution
The standard analyses of Inventory Controlling access two info
structures: S032, which contains the CURRENT stocks, and S031, in
which all the movements of the past are periodically aggregated
(usually monthly). Thus, the info structure S031 does not contain
ANY stock values for a past event. If you then start an analysis,
in which information on a stock and its value is queried in the
past, first the current stock is read from S032, and then all the
receipt values and issue values are added to or deducted from the
current stock up to the time of the date selected in the selection
of the analysis from S031. An example: The month is August 2002 and
you start a standard analysis, from which you want to determine the
stock of material XYZ in May 2002. Your current stock in August
2002 is 10 pieces. This information is obtained by the analysis
from S032. The analysis then reads the receipt values and issue
values from S031. Let us assume the following entries for material
XYZ in S031: Month-Receipt-Issue May-3 - 5 June -4 - 4 July -7 - 8
August- 0 - 0 Therefore the analysis performs the backdated stock
calculation in May as follows: Current stock = 10 pieces minus
receipt August (0) plus issue August (0) = 10 minus receipt July
(7) plus issue July (8) = 11 minus receipt June (4) plus issue June
(4) = 11 (Remark: the receipt values and issue values in May are
taken into account since the analysis always displays the stocks at
the END of the month). Hence the analysis displays a stock in May
of 11 pieces although the stock in May is not noted in any
information structure (because the stock is calculated instead of
being saved on the database). Therefore, in this instance, if you
see an incorrect stock in May 2002, this can have the following
causes: Your current stock is incorrect, and consequently the
system displays an incorrect stock value in all periods in the
past. An individual receipt value or issue value in S031 is
incorrect: Imagine you had the following incorrect entry (80
instead of 8 in the issue quantity) in S031 for July in the
aforementioned example: Month-Receipt-Issue July - 7 - 80 The
analysis performs the backdated stock calculation in May as
follows: Current stock = 10 pieces minus receipt August (0) plus
issue August (0) = 10 minus receipt July (7) plus issue July (80) =
83 minus receipt June (4) plus issue June (4) = 83
