Process Chains

Process Chains:-
---------------
* T-code to create PC - RSPC.
* Different Processes Connected like a chain we call it as PC.
* What ever we can do with event chains we can do the same with the help of process chains, But it will more Graphical and easy to monitor the Process Chains.
* Process / Variant
* Process :- Any Activity what we can perform in SAP BW.
ex:-
1) Deleting Index of Info Cube.
2) Create Index of Info Cube.
3) Roll Up.
4) Initial Fill.
5) Compression.
6) Info Spoke.
7) Load Data.
8) Attribute Change Run.
9) Reporting Agent Setting.
10) Deleting Data in the Cube.
11) ODS Data Activation.
12) PSA Deletion.

* Variant :- It is the object On which the process has to pe perormed.

* 2 types of Process Chains:-
------------------------------
1) Direct Chain :- It is a PC which can be scheduled directly.
2) Meta Chain :- It is a PC within another PC.

* Every PC must start with the Start Process.
* We can Deploy Parallism by using Process Chains.
* How to Create a Simple PC?
-----------------------------
Case Study:-
----------
P1 - > Delete the Index of the Cube ( ZY_PC)
p2 - > Load the Data to which cube ZY_PC
p3 - > Create the Index of the Cube ( ZY_PC)
p4 - > Rollup the req. to Aggregates (ZY_PC)
p5 - > Compression in ZY_PC.

Scenario:-
-----------
1) Loading it to cube

Process chains

loading data to ods
activation of ods
data loading from ods to ic
compression
indexes-----------activities---regular basys--------all these activities we r doing manuallly---remote user-----background as well


precocess chians is a seaquence of activites----designed in a proper way


data must be loaded ods
activate ods

delte the indexes from infocube
Data loading to icube


3 views----design view---to design ur process chains
checking view----to check the design of pchains
log view-----to monitor ur processes in the process chains----


services supported by process chains
1.general services
2.data loading services
3.data target administartion services
4.other bw services


variant----------------set of parameter to execute a job in the background
file sys--excel-----application server---(al11)

file---background-----application server



ss----------ods------icube



Process    variant

1.start process   start variant---when/how
2.delete the indexes on icube  on which icube
3.load data to ods   info package(background)
4.activate ods   which ods
5.ods to info cube data loading  ods
6.create the indexs---------------------------------icube
7.role up----------------------------------------------icube
8.compression   icube
9---db stat    icube


ss----------r3 sys
ods----------zods_ka
icube--zic-pc
isource------zis_nak
info package-------------ZIP_SD_NAK

RSPC-----TO DESIGN THE CHAIN

TO MONITRO THE PROCESS CHAINS------RSPCM



PLACING THE FILE IN APPLICATION SERVER-----------------TO SCHEDULE IT IN BACKGROUND//PCHAINS---PERFORAMCE ALSO IMPROVED
