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.
For the high performance mass data extraction from SAP tables we have developed the new custom function Z_XTRACT_IS_TABLE_COMPRESSION.
To install the new function module Z_XTRACT_IS_TABLE_COMPRESSION, please refer to Custom function module for table compression.
We recommend to use this function module, which is the successor of the custom function Z_XTRACT_IS_TABLE.
