BCS与BW主数据及层级结构同步

Manual Data Synchronization

Use

Applications that use the Financials Basis services, store their data in application-specific, local (partially dynamically generated) tables and in InfoObjects of SAP Business Information Warehouse (SAP BW). To prevent inconsistencies, the data must be identical in both storage locations. The necessary synchronization of the datasets normally takes place automatically by specialized services of the Master Data Framework.

The automatic data synchronization is successful only if the following prerequisites have been fulfilled:

• You have defined a leading fiscal year variant (in the Implementation Guide for Strategic Enterprise Management/Business Analytics under  Financials Basis Master Data Framework Periodicity Specify Leading Fiscal Year Variant for Whole Client  ).

• You have activated automatic data synchronization with SAP BW in your application.

   Example

  In SEM-BCS you activate automatic synchronization in the Tools view of the Consolidation Workbench under  Transport System Settings Replication in SAP BW  .

However, in certain constellations, the datasets can differ. These constellations are usually incorrect statuses that are caused by errors in Customizing, operator's errors, or errors in system communication. You implement the function described here to restore the consistency of data at both storage locations.

Integration

You can use the data synchronization for the following applications:

• Accounting Engine

• Bank Analyzer

• Master Data Framework

• Strategic Enterprise Management – Business Consolidation (SEM-BCS): Data basis and source data basis

• Strategic Enterprise Management ­– Business Planning and Simulation (SEM-BPS)

Features

You can perform manual data synchronization for master data and for hierarchies:

Synchronization of Master Data

The following programs are available:

• UGMD_BATCH_SYNC : This program replicates local data (master data and hierarchies) in SAP BW according to your selection settings. You can choose between two synchronization procedures:

  • Add-only synchronization : Only data is transferred to SAP BW that exists there in another form than in the local system or does not exist at all. Any other data within the selection in SAP BW remains unchanged.

  • Full synchronization : The data contained in the selection is deleted in SAP BW. The program then writes the data of the local system into SAP BW.

    You can save frequently-used selections as layouts and schedule the program as a one-time background job or as a regularly repeated background job.

• UGMDSYNC : This program replicates local data (master data, texts, and attributes, but no hierarchies) in SAP BW. You can also transfer BW data into the local system. For each selected object the program shows you the differences between the local version and the version in SAP BW.

  Your chosen selection settings are only used as a preselection for the quantity of data to be synchronized. You determine interactively which data you actually want to replicate from this quantity.

Both programs collect system messages generated during processing in a message log that you can analyze once processing has been completed.

Synchronization of Hierarchies

The following programs are available:

• UGMD_BATCH_SYNC : See above under "Synchronization of Master Data“.

• UGMDSY20 : This program replicates local hierarchies in SAP BW, however, only hierarchies of a combination of version and period that you have selected are taken into account. The field selection is limited to fields that are defined for a hierarchy.

  Your chosen selection settings are only used as a preselection for the quantity of data to be synchronized. You determine interactively which data you actually want to replicate from this quantity.

   Caution

  This program is not easy to use and therefore error-prone. We recommend that you do not use this program. Use UGMD_BATCH_SYNC instead.

Both programs collect system messages generated during processing in a message log that you can analyze once processing has been completed.
