Function Module for Tables
SAP customization for the Xtract Table component is optional. The installation of the custom function module /THEO/READ_TABLE is recommended to improve performance and to bypass restrictions of the SAP standard function module RFC_READ_TABLE.
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.
Installation of /THEO/READ_TABLE
An SAP transport request for the installation of the function module is provided in the installation directory: C:\Program Files\XtracIS\ABAP\.
Transport requests are imported into SAP by your SAP Basis team.
Note
Take a look at the README.pdf in the installation directory (e.g.,C:\Program Files\XtracIS\ABAP\README.pdf) before installing any custom function modules.
It is recommended to install the latest custom function module THEO/READ_TABLE:
| Transport Request | Compatible SAP Systems |
|---|---|
THEO_READ_TABLE_740SP05.zip | ABAP version 7.40 SP05 and higher |
THEO_READ_TABLE_710.zip | ABAP version 7.10 to 7.40 SP04 |
THEO_READ_TABLE_640.zip | ABAP versions from 6.40 until 7.03 |
THEO_READ_TABLE_46C.zip | ABAP versions from 4.6C |
When importing the transport requests on older SAP releases a syntax error may occur. Contact Theobald Support and send the dedicated error message text.
Warning
Generating Short Dumps.
Testing the function modules on an SAP system is not possible. Function modules /THEO/READ_TABLE and Z_THEO_READ_TABLE can only be called by Theobald Software products due to the callback function of the module. Avoid calling function modules /THEO/READ_TABLE and Z_THEO_READ_TABLE directly from an SAP system.
