Dataflow overview

Summary

The dataflow can be divided in 3 main steps:

1. check that no other run are in progress (a) and then extract data from BW to PCM SQL database 
   1. Extract master data in full mode to csv files through openhub (b)
   2. Load FIAR and CAMS data into specific DSO build for PCM project (DBFIAR20 and DBFIAR21),then extract to csv through openhub
   3. launch ksh script (c) to execute treatment on PCM SQL database side (through OS Command (d))
2. treatment on PCM SQL database side
3. load data from PCM SQL database  to BW
   1. when OS command is finished (meaning that treatment are finished), load the status table (e)
   2. if code in status table is 0, load PCM data into 2 specific DSO, DPFIAR10 and DPFIAR11, else regenerate file or put process chain in error

Functional and Technical rules on Workbench + Reporting

Rules & Explanations

The whole process can be summarized has follow:

• Extraction of BW data (master and transactional data) in flat files (csv with "|" separator)
• copy and loading of these file into a SQL database
• Calculation of predictive information on SQL side to produce two table which define Priority per Amount & Priority per Payer
• Loading of these data in BW to be used on standard reporting

Program (a)

(created in SE38)

2 program to update the TVARVC variable Z_BW_PCM_PC_STATUS

The purpose of these program is to avoid launching process chain twice if previous run is still active.

If the process chain is already running, the process chain will fail requiring deeper analysis (normal duration should be less than one hour - only init run should exceed this duration)

Openhub (b)

7 openhub have been created for master data and 2 for transactional data

All master data openhub are loaded in full mode. All extract data from master data except the TCURR one which is connected to a datasource.

All transactional data openhub are loaded in delta mode. (remark delta is not possible with multiprovider).

All openhub use a "|" separator because some field already contain ";" in the value and openhub doesn't encapsulate data.

All openhub use logical file name defined through FILE transaction. All files are stored in the following folder

KSH script (c)

KSH script have been build by D3S/adagio team.

They are stored in the following folder

pacm-ping.ksh is the initial test for the PCM project (not used anymore).

pacm-reset_db.ksh allow to reset SQL database from BW.

pacm-run.ksh is the script which launch treatment on SQL database side. It generate a log in the following folder: /exploit/TA/tmp/${STAMP}_log_run_$server.log

This scripts awaits two parameter:

• server 
  • WDCPAAP21.eua.solvay.com (in WBP, see OS command for more detail)
  • WDCPAAT21.eua.solvay.com (in WBQ / WBD)
• and user
  • PA_SVC_PRD (in WBP, see OS command for more detail)
  • PA_SVC_TST(in WBQ / WBD)

OS Command (d)

(created in SM49)

The ZPCM_RUN launch a .bat file which load extracted file in the D3S SQL database. It's included in process chain through the following variant:

This variant has been modified directly in WBP to launch treatment on the SQL production server

The ZPCM_RESET_DB reset the database. It's not included in process chain

Status table (e)

The status table is loaded in DSO DPFIAR12

C_COMMAND should be used to run the "ZPCM_RUN" or the "ZPCM_RESET" depending on the value sent by SQL database. This functionality is not used and by default the process chain always launch the RUN. If the RESET is required, then it needs to be launched manually.

C_CODSTAT can take 3 different value which are checked in the process chain:

• 0: "normal" process
• 1: problem with file generated, the process chain will try to generate file again (only once)
• 2: other error, the process chain will fail and deeper analysis is required

These value are checked in the process chain through "Enhanced decision"
