Maintain Update
Rules
Update rules help you to define updating in
detail.
The definition of the update rules depends on
the information structure and update group.
Update rules consist, for example, of the
source field, the event which triggers the update, requirements and
formulas.
Once you have defined the update rules, the
corresponding update programs are automatically generated.
In this IMG activity, you can create, change
and display update rules.
Note
Once you have defined the update rules, you
then need to activate the update in a separate step.
The creation of update rules, the generation of
the update programs, and the eventual activation of the update have been
divided up into separate steps for security reasons.
Activities
1. In the "Info
structure" field, specify the name of the info structure for which you would
like to maintain the update rules.
2. Allocate an
update group to the information structure in order to establish an
application-specific reference.
3. If you wish
to create updating for the information structure with reference to an existing
update for an information structure, enter the name of the information
structure in the field Copy from -> info
structure and the name of the update group to which you are
referring in the Copy from -> update group
field.
4. Press
Enter.
You are now in the
update rules maintenance screen.
The maintenance
screen lists all of the key figures in the information structure for which you
can define update rules.
If no update rules
have been defined by the time that updating is created, then all available
information from the information structure definition will be
proposed.
5. In order to
reach the detail screen of the updating definition, place the cursor on the
key figure you require and select the Edit -> Rules for key
figures function.
6. Define the
individual update rules.
7. When you
have defined all of the update rules for the key figure, select the
Copy function.
The update rules
that you have defined will be copied and displayed in the maintenance
screen.
8. Procede in
the same way for the other key figures.
9. In addition
to the update rules for the key figures, define the update rules for the
characteristics.
Place the cursor on
the desired key figure and select the Edit -> Rules for
characteristics function.
You are now in the
detail screen for maintaining the update rules for the
characteristics.
Note
You must define the
update rules of the characteristics for each key figure so that the key
figures can be updated when different events occur.
The update rules for
the characteristics can be different for each key figure.
10. Define the
individual update rules.
11. When you
have defined the update rules for all key figures and characteristics, save
these update rules.
12. Generate
the update from the update rules.
Before the
generation, all of the update rules are checked for consistency. Possible
inconsistencies are documented in a log and generating is
canceled.
You can also start
the check independently by selecting Updating ->
Check.
If no errors occur
during the check, the update is generated.
A log is issued
after generation is completed.
Additional
information
You can also make use of the following
additional functions when defining update rules:
If you would like to
exclude key figures from the update (for example, when using a specific update
group), place the cursor on the correspondingkey figure and select
Edit -> Delete rule .
The update rules are
then deleted for the key figure and the corresponding characteristics that you
selected.
The "restore"
function is closely connected to the delete function.
If you delete the
update rules for a key figure by mistake, you can reactivate this key figure
by selecting it from the list of key figures that have not been
used.
To do this, select
Edit -> Restore -> Key figures.
A dialog box appears
which lists all of the key figures that you have defined in the information
structure but which you have not used in your update definition.
Select the key
figures which you have not yet included in your update.
Press Enter
to copy the selected key figures.
This, however, does
not restore all of the update rules that you might have defined.
Only the source
field information that was already specified in the information structure
definition is copied.
You need to use this
function if you would would like to define more than one update for one key
figure.
The best way to
explain this function is to use an example.
Example
You want to update
the open order quantity.
The open order
quantity is defined as the order quantity that has not yet been
delivered.
Customer order
processing updates the "open order quantity" field.
When a delivery is
entered, the open order quantity should be reduced.
When defining
updating for this process, you need to define two update rules for the key
figure "open order quantity".
The first update
rule describes the upate for the event "sales order". Here, the key figure is
updated from special source information in the document (MCVBAP-OAUME) that is
provided specifically for this purpose.
The second update
rule describes the reduction of the open order quantity by the delivered
quantity for the event "delivery".
Here, you need to
copy the first update rule and change the event and the and the source
information.
The quantity
delivered is also made available for updating in a special field
(MCLIPS-APOAUME).
Since the open order
quantity is reduced by the delivered quantity, the information is then shown
as a negative value.
The open order
quantity that is established by the first update rule is then reduced by the
second update rule.
Note
This is a special
case, where the delivered quantity is automatically displayed as a negative
value to reduce the open order quantity.
If you would like to
express differences in different ways, where the second update is supposed to
reduce the value of the previously updated value, for instance, use a formula
to invert the process.
