What is table analysis variant in data archiving? what is use of Tcode TAANA_VF?

 To analyse table for database archiving is prerequest of Database analysis and to do so we use Tcode TAANA. In TAANA after selecting a table we need to provide a Variant to be able to execute a table analysis (transaction TAANA) you always need an analysis variant. A variant belongs to exactly one table and describes which fields should be analyzed.

There are two kinds of analysis variants:

  • Analysis variants that you create in transaction TAANA_AV. The definitions of these variants are saved on the database and are available for future table analyses.
  • Ad hoc analysis variants, which you create when you schedule a table analysis (transaction TAANA). The definition of this type of variant is not saved on the database and is, therefore, only available for the table analysis you currently scheduled.

Activities related to Analysis Variants

  • Creating an Analysis Variant
  • Creating Virtual Fields
  • Displaying Analysis Variants
  • Deleting Analysis Variants
  • Creating an Analysis Variant

             To perform a table analysis, you always need an analysis variant. This relates to only one table and describes which fields are to be analyzed. The system saves the analysis variant to the database; it can then be used for future table analyses.

With the transaction:

  1. TAANA_AV or alternatively
  2. Starting from the table analysis (transaction TAANA), choose Environment  Analysis Variant.
  3. to go to the change mode for analysis variants for the table analysis.
  4. Choose Edit New Entries and enter the name of the table for which you want to create an analysis variant.
  5. Enter the name of the analysis variant that is in your namespace.
  6. Choose Fields. The system offers you all table fields for selection.
  7. Select the relevant fields or create virtual fields if necessary. For more information, see Virtual Fields.
  8. Save the analysis variant.
  • Creating Virtual Fields

Procedure

1. The following alternative access options are available:

Enter the transaction TAANA_VF.

Enter transaction TAANA and choose Environment  Virtual Fields.

Enter transaction TAANA_AV and choose Environment  Virtual Fields.

2. Choose Edit  New Entries and enter the name of the table for which you want to create virtual fields.

3. Enter a name for the new field. Make sure it is within your namespace.

4. Enter the data for the value determination and technical attributes of the field.

5. Save your entries.

  • Displaying an Analysis Variant

    In transaction TAANA_AV, you can find on the left-hand side of the screen a list of all the analysis variants created, sorted by table names. To display an analysis variant, double-click on it. The analysis variant is then displayed on the right side of the screen.

  • Deleting an Analysis Variant

    To delete an analysis variant, display the variant you want to delete on the right side of the screen. Choose Edit  Delete.

Data Archiving importance in SAP S4HANA System

  #HANA #S4HANA #SAPBASIS

Data archiving in SAP S/4HANA is an essential practice that helps organizations manage data volumes, enhance system performance, 

ensure compliance with legal regulations, and optimize operational efficiency. This report delves into the importance of data archiving 

in SAP S/4HANA systems and outlines the country-specific rules regarding archiving practices.

 

Importance of Data Archiving in SAP S/4HANA

 Data archiving in SAP S/4HANA offers significant advantages, including resource optimization and improved system functionality. Firstly, as organizations accumulate vast amounts of data, the archiving process allows them to remove obsolete or inactive data from the operational database. This leads to a substantial reduction in storage costs, especially since HANA memory can be quite expensive.

 Additionally, by keeping the operational database lean, data archiving enhances system performance and response times. A lightened database improves overall agility, making data retrieval and processing quicker and more efficient. Furthermore, effective archiving also bolsters an organization’s cyber resilience by facilitating faster data recovery in the case of data breaches or cyberattacks.

 Compliance is another essential aspect of data archiving. Organizations are often required to comply with various legal regulations regarding data retention, which dictate how long specific data must be stored. Data archiving enables businesses to retain necessary records while safely removing unnecessary or outdated information. This not only ensures regulatory adherence but also mitigates penalties associated with non-compliance.

 Benefits of Archiving in S/4HANA Migration

 Implementing data archiving strategies is crucial during the migration to SAP S/4HANA. Archive management can dramatically reduce the complexity and duration of migration tasks, as less data results in shortened migration windows. Efficient archiving allows organizations to focus on migrating critical data, thereby expediting the overall process and reducing risk.

Moreover, data archiving aids in preserving historical data, which is crucial for legal compliance, audits, and reporting. Archived data remains accessible, allowing authorized personnel to retrieve and analyze it effortlessly when required.

 Conclusion

Overall, data archiving in SAP S/4HANA systems is indispensable for optimizing operational efficiency and ensuring compliance with diverse legal regulations.
