General presentation

Objective of the application

This application extract the forecasts from the application APO. The data is loaded and aggregated in BW and made accessible through a multiprovider which regroups data from three application. APO, Dynasys and Logility. In time, application Logility will be terminated and the data coming from APO should be integrated in Dynasys.

Tool Leader + IT leader of the application: Celia Gonzales

Functional and Technical rules on Workbench + Reporting

Rules & Explanations

1 : Cleaning of incoming data before propagation datastore objects

C_MATNR2: adjust the format of the material number to the right number of digit, adding/removing zeros in the process.

0LOGSYS : Determination of system source

C_SHIPTID & C_SOLDID (only for Special Chemical): Removing of source system extension and adjustment of the format 

2 : Determination of previous period for C_FCSTMTH when loading the snapshots

It's usually the previous month. It can however be fixed to a specific value through the use of filters in masterdata C_GLBFILT

3 : Loading of attributes from MD for all DSOs

  • BFC Global Business Unit (CPFCTR1_2) is retrieved from the corresponding attribute of Material Plant (C_MATPNT2).

C_MATPNT2 is determined through the coupling of material and plant and is used for business assignments (ERP or BFC). It contains multiple attributes mainly loaded through either the standard attributes from datasource 0mat_plant and the MD C_SUBACT2 (a mix of Profit center (WP1) and Business area (PF1, PI1 and RHO systems)).

  • Customer Group - Enterprise (C_CUSTGRP) is retrieved from the corresponding attribute of Customer - Enterprise Axis (C_CUSTENT).
  • Company code (C_COMPCODE) is retrieved from the corresponding attribute of Main Shipping Plant (C_MPPLANT).
  • Sales Office (C_SAL_OFF) and Sales Document type (C_DOCTYP2) have been initialised with value APO.

4 : Loading of attributes from MD for loading coming from RCS (Every DSO except the two for Special Chemicals)

  • Division (0DIVISION) is retrieved from the corresponding attribute of Material (C_MATNR2).
  • Sub-Activity (0G_CWWE01), also known as Iecra, is retrieved from the corresponding attribute of Technical GBR Deter CDSA Payer (C_CDSA).

C_CDSA contains the distribution channel coupled with division. The IECRA can also be found in C_MATPNT2, but it's value is wrong.

5 : Loading of attributes from MD for loading coming from SOLVAY (Only the DSO for Special Chemicals)

  • Material Group (C_MAT_GRP) is retrieved from the corresponding attribute of Material (C_MATNR2).
  • Ship-To-Country (C_SHTCTRY) is retrieved from the corresponding attribute of Ship-To-Party (Core) (C_SHIPTID).
  • Sub-Activity (0G_CWWE01) is retrieved from the corresponding attribute of Material Plant (C_MATPNT2).

IECRA is specified in this dataflow as an information but is not reliable. IECRA is not an organizational structure used in Solvay.

  • Commercial Product/Material Group (C_PROD) is retrieved from the corresponding attribute of Material (C_MATNR2).

Commercial Product for RCS and Material Group for Solvay

6 : Keyfigures in summation when loading the business datastore objects

Data in APO can't really be aggregated in a DSO as every characteristic is key (like in an infocube). This means that the semantic keys which were determined for the propagation level is not absolute. Since the DSO are in write optimized, there is no loss of data thanks to the techical keys. It is necessary however to load the key figures in sommation at business level.

7 : Determination of Concerned Period (C_FLGMTH) for dynamic dataflow

We are always loading data for current month M

8 : Determination of Concerned Period (C_FLGMTH) for snapshot dataflow

The month view is determined depending on the difference between the period 0CALMONTH of the forecast and the considered period C_FCSTMTH (date of the photo).

IF 0CALMONTH = C_FCSTMTH THEN C_FLGMTH = 'M'

ELSE IF 0CALMONTH > C_FCSTMTH THEN C_FLGMTH = 'M-2, M-3,...' (There is no M-1)

ELSE C_FLGMTH = 'N/A'

Examples:

Calendar Year/Month

08.201607.2017N/A

9 : Determination of GH quantity and bias for snapshot dataflow

For each snapshot loaded in a business datastore object, we rework the entire datastore object. We update the Gross History quantity for past snapshots using the latest GH quantity depending on the keys of the DSO.

There is 3 bias which are calculated:

  • The bias for the final forecast is calculated through the following:  ABS ( FF Quantity - GH quantity).
  • The bias for the sales team forecast is calculated through the following:  ABS ( STF Quantity - GH quantity).
  • The bias of the statistical forecast is calculated through the following:  ABS ( STATF Quantity - GH quantity).

Dependencies with other applications

This dataflow is using the same multiprovider than the dataflow for dynasys. Therefore when modifying multiprovider MVDYN11, beware of the impacts.

The loading of the snapshot part is done on the same day than dynasys.

Data loadings

Info providers and objects loaded

There is a high volume of data for the snapshot dataflow, which is why a clean-up was established during the loading in the PC. We keep only 36 months of history. The deletion process is done on every layer.

As the snapshot and dynamic dataflow use the same source, a decision tree was used to stop one loading if the other is already on-going.

36 Months of history

DSO Backup

The DSO DBAPO012 is available if necessary to backup the data of a dso on business layer. This is used especially when there is a need to change the structure of a core DSO.
