ERP transaction CKMLQS has been designed to display the multilevel valuated quantity structure for one material.

The aim of the multilevel valuated quantity structure is to provide an overview of the actual quantity structure of the multilevel processes, valuated with the actual prices from the actual costing.

I will try explain the steps, how to create BW on HANA custom datasource for mass reporting.

Activities:

  1. -Abap function module developments
  2. -Standard ERP program methods abap repair activities
  3. -BW on HANA datasource creation and modeling
  4. -Conclusion



  • Abap function module developments

Transaction code CKMLQS input screen consist of some input parameters.

Material, Plant, valuation type, Sales Document, WBS Element, Period, Year

Sample input screen,





SE38 program that runs behind CKMLQS transaction is CKML_QSTREE.

Output values of CKMLQS is a hierarchical tree structure form.





Main purpose is to report the values of CKMLQS output values below hierarchy node (for this report demand) PROGRASIF( how much energy, labor and other details consumed, quantity of amortization, quantity of waste material consumed ) for producing product during a period for mass reporting in BW on HANA side.

For the selection input values given above, the output values of hierarchy’s sub node consist of some hierarchy item values.

SE37 custom-based abap function module development,

  • Standard ERP program methods abap repair activities

I created Z custom BW datasource with function module option, and test the values on some variants on selection screening on RSA3, period and plant , control bilateral BW datasource and CKMLQS transaction.

Both side values are consistent.

When trying to load values of datasource with giving infopackage selection (period and plant ) to BW side datasource load 0 records.

When trying to load BW on HANA datasource on some infopackage selection, datasource tried to load not only table fetch or BOM explode output values , but also datasource tried to load SAPGUI screen elements ( init toolbar control, customer container creation, GUI hierarchical tree control and display events) to BW side and data load fails to 0 records.

Programs run according to one of two options,

BACKGROUND or FOREGROUND.

Triggering BW on HANA nfopackage whether manually or via scheduled process chain, BW on HANA datasource programs always run in BACKGROUND.

Inputting some selection to any ERP transaction program ( e.g: CKMLQS ) SY-BATCH is equal to SPACE and is always run in FOREGROUND.

Debug screenshot any method part of CKMLQS and run foreground,

SY-BATCH = SPACE





When executing a infopackage in BW side, adding necessary SY-BATCH control to skip some ( init toolbar control, customer container creation, GUI tree control and display events) of (call method cl_qstree_ckml) class interface sub methods results a successful data loading to BW on HANA system.

I made abap repair activities (core abap program changes) on (call method cl_qstree_ckml) class interface 3 sub methods codes as shown below.

I commented the original lines and add same code below with a extra line of sy-batch control.

When the infopackage triggered in BW on HANA side, SY-BATCH set to TRUE and skip this me->init_toolbar method for not trying to get toolbar elements to BW on HANA side.

me->init_toolbar initializes GUI Toolbar.

When the infopackage triggered in BW on HANA side, SY-BATCH set to TRUE and skip this CREATE OBJECT mr_treecontrol method for not trying to load Initialized Custom Container and ALV Tree to BW on HANA side.

With the help of giving some infopackage selection range parameters, mass loading of CKMLQS material ledger values successfully loaded to BW on HANA datasource.

  • Conclusion

I create custom-based Z function module for BW on HANA datasource backend to load data as a cumulative load, e.g: loading with plant and period value infopackage selection.

After loaded data to BW on HANA side as 0 records, i noticed that when loading data from transaction CKMLQS SAPGUI elements are also passed via program .

I add some condition controls on this standard methods for not trying to load SAPGUI elements to BW side during BW on HANA mass loading .

Code logic for methods for skipping SAPGUI elements when data loaded to BW on HANA (BACKGROUND),

IF sy-batch = ABAP_FALSE. // if program run in FOREGROUND

EXECUTE GUI METHODS.

ENDIF.

After adding controls on this methods, data are mass loaded to BW on HANA datasource successfully.

Both BW on HANA datasource and ERP tcode CKMLQS consume 3 repaired methods.

When user trigger CKMLQS transaction , ( it is a FOREGROUND activity ) methods work same as before method changed.

When BW infopackage triggered for loading data to BW side ( it is a BACKGROUND activity ) program skip the SAPGUI places for not trying to load screen elements(docking, container, screen display) to BW on HANA side.

That’s all steps.
