There are several restrictions when using the SAP standard:
- 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 “floating point”.
If these restrictions hinder your work, please use this setp-by-step guide to install the Z-function in your SAP system.
To install the standard function module Z_XTRACT_IS_TABLE, please refer to Table Restrictions. After installation check setting “Use Custom Function” to enable the Z-function module.
Alternatively, you can also use the following function modules delivered by SAP, if available on your SAP system:
- /SAPDS/RFC_READ_TABLE, /SAPDS/RFC_READ_TABLE2, /BODS/RFC_READ_TABLE, /BODS/RFC_READ_TABLE2
