Safety instructions

In the unlikely event of a loss of cabin pressure …

Re-execute KEHW with “force initial load” option

  • This will drop the tables on HANA side
  • Everything is regenerated
  • Fresh data load happens

…however, you need time

We recommend customers continue to maintain and build u traditional summarization levels for 3-6 months after CO-PA accelerator adoption. This will allow to set the accelerator inactive anytime falling back to the situation before.

Reconciliation program

The number of records in CE1 & CE2 table are automatically reconciled with each replication run You can manually start the reconciliation with program RKE_HDB_RECONCILIATION The program allows to transfer entries missing in HANA (not vice versa) and offers different details of log display.

General considerations

Over time, we expect SLT or other HANA replication mechanisms to become the predominant tool.

The data provisioning via CO-PA program is meant to be the easy –to implement, low TCI solution as it builds on the connection required for read access. It also provides built-in support & status handling for the DO-PA scenario.

Using SLT, there is no dedicated mechanism for transferring the object table (CE4). Changes are simply replicated when they happen.

SAP ERP RDS for profitability analysis with SAP HANA – allocations

Basics

CO-PA accelerator will speed up the selection of CO-PA data during the allocation process

  • Selecting reference data for assessments from CO-OM into CO-PA
    • g. you want to allocate overhead cost from cost centers to customers proportionally to sales quantity
    • Selection of sales quantity per customer will be accelerated
  • Selecting data and reference data for top-down allocations inside CO-PA
    • g. you want to disaggregate marketing costs from ——– groups to single customers proportionally to sales quantity
    • Selection of sales quantity per costume will be accelerated
    • Selection of Data w/o customer assignments 9to be disaggregated) will be accelerated

CO-PA accelerator will not speed up

  • Allocations inside CO-OM
  • Selection of data from CO-OM for allocation into CO-PA
  • Processing & posting of allocation data

Efficient access to data by any criterion E.g. all data without product attribute which needs to be allocated to productsRead access for any field can be difficult to support by indices

Principle of acceleration

The acceleration effect originates from the efficient aggregation of amounts along any dimension. Here: revenues by division required for determining percentages for allocation.

Example for assessment with variable reference data

Assessments from cost centers into CO-PA will only be accelerated if receiver tracing factor (reference data) is variable.

Top-down allocations

Example: allocate overhead marketing cost to products according to billing quantity per product

SAP ERP RDS for profitability analysis with SAP HANA – Allocations

Top-down allocation analysis

Via the log of top-down allocations, you can find out now much time is spent on selection of source and reference dat.

e.g. in this example, 54.780 subtotals have been derived form several millions line items as reference for the allocation in 28 secs

Read runtime analys is You may use the log for CO-PA read interface to analyze selection behavior of allocations.

Considerations for maximizing performance Look for allocations where

  • Runtime of selection is high
  • Selection of reference data is aggregating
    • Reference data “sales per customer group” will yield better performance than “sales per customer”
  • Reference data is variable selection

Consider different allocation rules

  • g. you may today allocate data from cost content into desired level in CO-PA in one step
  • Due to the CO-PA accelerator, it may be more efficient to assess data from Cost Centers into CO-PA on a higher level and then ran a top-down allocation inside CO-PA

Acceptance and performance Test in CO-PA

Steps:

  • Prepare for testing
  • Check your CO-PA Reporting accelerated by SAP HANA
  • Finally accept the provided solution

As SAP HANA will accelerate your CO-PA Reporting, it is important to know how this works. The following slides will describe the main facts.

SAP ERP rapid-deployment solution for profitability analysis with SAP HANA – ERP Reporting

Basics

CO-PA accelerator will speed up the selection of CO-PA data for reporting

  • Existing ERP reports will continue to work without visible change to the user including calculations, layout, authorizations.
  • For optimum performance, use certain options (see next slides)
  • With CO-PA accelerator, the application will read from ——– HANA line items instead of usual summarization levels / totals table.
    • You can specific in customizing transaction KEHC—————– to control in detail which reports should read form HANA and which should stay in traditional mode
  • You may use from-based or ad-hoc reports.
  • ERP Drilldown reports (on totals / ——–) will only offer characteristics of totals table independent of technical access to line items in HAN.
  • ERP Line item reports (KE24) will be redirected to HANA as well. However, some performance-relevant options (“read upon each navigation step”) are not available for line item reporting.
  • For full flexibility in line item reporting, consider reporting directly out of HANA.

Important settings

Make sure to use the aggregation in HANA and not in the application server when navigating in the report (option “read upon each navigation step”).

The settings for summarization data will be ignored if CO-PA accelerator is active.

Characteristics are identical to normal system to allow fallback

The available characteristics in defining reports are restricted to the ones available in totals table –although the technical read access is on line items with CO-PA accelerator.

Rationale:

  • Zero disruption for customer
  • Possibility to run identical report with and w/o CO-PA accelerator.
  • SAP ERP rapid-deployment solution for profitability analysis with SAP HANA – ERP Reporting
  • Defining reports on line item characteristics
  • Standard reporting will only allow characteristics of totals table. Line item reports will give you access to item characteristics and thus all HANA fields.\

Next Steps:

  • Identify the most important reports for your business
  • Identify the long running and low performing transactions
  • Start the reports without SAP HANA acceleration
  • Note the runtimes
  • Enable SAP HANA acceleration
  • Start the reports and transactions again and check the performance
  • Finish testing
