BCT-CO delta DataSources: Technical background information

Symptom

This note provides technical background information on the extraction of transaction data from the CO

via the 0CO_OM_CCA_9, 0CO_OM_WBS_6, 0CO_OM_OPA_6, 0CO_OM_ABC_7, 0CO_OM_NWA_2,

0CO_OM_NAE_2 and 0CO_OM_NTW_2 DataSources.

This information provides customers and SAP service employees with more effective solutions and a

better understanding of the problems.

Having a better understanding of the problems reduces the time required to process them.

Other terms

The following commitment line item DataSources are based on the same technology:

0CO_OM_CCA_10, 0CO_OM_WBS_7, 0CO_OM_OPA_7, 0CO_OM_NTW_3,

0CO_OM_NWA_3, 0CO_OM_NAE_3

For information on the availability and delta capability of these DataSources, see note 543386.

Reason and Prerequisites

This is due to some technical background information that was missing.

Solution

1. For information on CO delta extractors, refer to the following area in the BW documentation:

Business Content/Financials/Controlling/Subapplication/InfoSources.

In particular, refer to the link to the "delta extraction" area from the documentation of the

relevant InfoSource.

2. All CO delta-extractors select data from the CO line item table for COEP actual data via the COVP view.

The time stamp (TIMESTMP field) is used in the line items as a criterion for the delta process. To

allow efficient access via this field, you must manually activate index 4 for the COEP table on the

database - as described in the documentation. An inactive index is delivered on the database in the R/3

standard system.

The history of the extraction runs and the time intervals that have already been extracted are

updated in the BWOM2_TIMEST table (BWOM2_V_TIMEST view).

A distinction is made between the following runs via the UPDMODE field:

(F) Full

(D) Delta and

(S) Simulation

For technical reasons, the system only extracts up to the upper limit of the last delta run that has

already been extracted when you repeat the initial run.The following delta run then delivers all data

considered during the safety interval.

The CO delta extraction only selects (by default) line items that have been posted in a 120

minute safety interval before the extraction run is started (this is to ensure that the update is not still

running for the extracted time interval).

By adding a new entry to the BWOM2_SAFETY table (BWOM2_V_SAFETY view) for the

DataSource, the safety time interval can be defined on another minutes value for test purposes, but we

would strongly advise against implementing a change for the production operation (for more

information, see note 553561).

The line item selection is performed in the BWOMR_OM_READ_COVP_DATA function module

(via the COVP view).
