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:
TAANA_AV or alternatively
Starting from the table analysis (transaction TAANA), choose
to go to the change mode for analysis variants for the table analysis.
Choose
and enter the name of the table for which you want to create an analysis variant.Enter the name of the analysis variant that is in your namespace.
Choose Fields. The system offers you all table fields for selection.
The system first displays the fields contained in the ABAP Dictionary (DDIC). Then it displays the virtual fields defined in the table analysis.
An analysis variant should contain as few field as possible (three to four fields). You should only choose fields with a low selectivity, meaning with few characteristic values. Fields having high selectivity, for example document numbers, mean that the results list for a table analysis is unduly long, which both reduces its usefulness and also takes up too much space in the database.
Select the relevant fields or create virtual fields if necessary. For more information, see Virtual Fields.
Save the analysis variant.
The new analysis variant is displayed on the left-hand side of the screen.
