Tables

This section shows how to use the ReadTable class.
A recurrent task when working with SAP and .NET applications is to read directly from tables of the SAP system. The ReadTable class enables access to that data.

Note

The RFC_READ_TABLE function module for table extractions is not suitable for mass data extraction, see Restrictions.

Restrictions

When extracting tables from older SAP releases you may encounter several restrictions when using the SAP standard function module (RFC_READ_TABLE):

  • The overall length 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.

Warning

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.
