Table

This page shows how to use the Table extraction type.
The Table extraction type can be used to extract data from SAP Tables and Views.

Supported SAP Objects

  • Transparent tables
  • Views
  • ABAP CDS Views (without parameters)
  • HANA CDS Views
  • Pool tables (joining not possible)
  • Cluster tables (joining not possible)

RFC_READ_TABLE Restrictions

Especially with older SAP releases you may encounter a few restrictions when using the SAP standard function module (RFC_READ_TABLE) for table extraction:

  • The overall width of all columns to be extracted must not exceed 512 bytes.
  • It is not possible to extract data from tables that contain one or more columns of the data type f (FLTP, floating point), DEC (decimal, e.g. for percentage) or x (RAW, LRAW).
  • Poor extraction performance with larger tables. Can cause also duplicates.
  • Depending on the SAP version there may be other restrictions.

When facing restrictions, install the Theobald Software custom function module /THEO/READ_TABLE on your SAP system.

Warning

Converting issues
Error while converting value '*.0' of row 1530, column 3.
The SAP standard module RFC_READ_TABLE for table extraction can only extract the ABAP data type DEC to a limited extent. This leads to the mentioned example error during extraction. Use the function module /THEO/READ_TABLE.

Prerequisites

Warning
