Aggregates Function
The following aggregation functions are available for column contents:

  • None: No aggregation
  • AVG: Average
  • COUNT: Number
  • MAX: Maximum
  • MIN: Minimum
  • SUM: Total

Use Conversion Routine (Conv.)
Defines whether the conversion routines stored in the Data Dictionary are used for the respective fields. Typical examples are the language key (for example, D in the database, but DE after conversion) or the project number (for example, T000012738GT in the database, T/12738/GT after conversion). After the conversion, the value is always displayed as it would appear in a transaction in the SAP GUI. This option is only supported with function module Z_THEO_READ_TABLE.

Load live preview
The Load live preview button allows a real-time preview of the extraction data without executing the extraction.
You can also preview the data with aggregation functions.

Count rows
Returns the number of rows/data records of an extraction, taking into account the WHERE and HAVING Clauses stored.

Refresh metadata
A new lookup is performed on the selected table(s). Existing mappings and field selections are retained, which is not the case when the table is added again.
It may be necessary to renew the metadata, for example, if a table has been adjusted on the SAP side, another source system has been connected, or the source system has been updated. In such cases, data inconsistencies can occur that are resolved by this function.
