[ZT] Important points of creating planning book

34 Views

From one SAP site:

Some hints on the design and usage of macros for background processing:

u2022 Create a separate planning book for each macro background job. The planning book should

contain only key figures used by the macro itself, and only macros executed as activities by

the mass-processing job. Use a different planning book whenever different key figures are

needed by two macros, and a different data view whenever the time periods are different.

u2022 Remove all unused macros from planning books associated with mass processing jobs, as

they are loaded in an unorganized manner which can be performance-intensive. Unused

macros are not helpful to your business process.

u2022 Only those macros that are called by an activity are executed in background. These activities

are: Start, End, Level change. Default macros are not executed automatically, as they are in

dialog. When defining a job, you must therefore first establish which start and default macros

have to be executed and in which sequence, so that your own self-defined macro can work

correctly. Macros for background should not involve actions like setting colors, hiding fields,

display icons, or sending popup windows that are frequently included in default macros for

online use.

u2022 The planning book used for background macros should have only the functionality it uses, i.e.

application demand planning and no other functionality.

u2022 For performance reasons, run macros for a delta period rather than the entire horizon

wherever possible. Under most circumstances, historical data is not changed, other than

adding new periods, one time bucket profile at a time. Rather than performing the full

calculation over a long historical period, run a macro to do this once, and then design a new

macro that only performs the calculation for the u201Cdeltau201D period, or the period that has just

entered the historical horizon.

u2022 If you want to speed up the processing in the APO releases 3.0A, 3.10 and SCM 4.0, you can

create several background jobs with roughly equal numbers of characteristic combinations

and run them in parallel. Make sure that no individual characteristic combination belongs to

more than one selection variant, as this can cause lock issues. For optimum performance the

selections for parallel processing should be roughly of the same size.

u2022 From release mySAP SCM 4.1 you can use parallel processing profiles for running macros,

e.g. for the adjustment of historical data. You can navigate from transaction /SAPAPO/MC8E

directly to the maintenance of parallel processing profiles or start transaction

/SAPAPO/SDP_PAR for direct access. After defining block size and number of maximum

parallel processes you have to assign the parallel processing profile to the selection variant.

The next time you run this selection as background job it will automatically run with parallel

processing.

u2022 If you need to run two macros on the same key figures with the same level of aggregation, put

both into one planning book and execute them as two actions within the same background

activity (defined with transaction /SAPAPO/MC8T, see below). You thus save the time needed

for loading the data for a second time.
