Opening Extraction Settings #
Within the window “Extract Single and Joint SAP Tables or Views” click Extraction Settings. The window “Table Settings” opens.
Table Settings #
The window “Table Settings” consists of two subsections:
- Extraction Settings
- Function Module
Extraction Settings #
Specifies the number of records retrieved per data package. Optimal values can be found by trying out. The default value is 20000 lines. A package size between 15000 and 50000 is advisable for large amounts of data. 0 means no packaging. Not using packaging can lead to an RFC timeout for large data extracts.
Recommendation: Especially when executing a table extraction as a background job (see Extract data in background job), the package size plays an important role and should be chosen with regard to the total amount of data.
Specifies the maximum number of extracted records. 0 Extracts the entire table.
Function Module #
Specifies the name of the function module used for data extraction. The field is filled automatically depending on which function modules are installed on your SAP system.
Recommendation: For better performance and restriction avoidance use the function module from Theobald Software Z_THEO_READ_TABLE. See also SAP Customizing.
Extract data in background job
If this checkbox is checked, the table extraction is executed as a background job in SAP. Extract data in background job setting is optional and is supported in combination with function module Z_THEO_READ_TABLE as of version 2.0. Activate the setting Extract data in background job for long-running extractions with a very large amounts of data that run into a timeout error (“Time limit exceeded”), when using the standard method.
Tip: the extraction jobs can be found in the SAP JobLog (SM37) under the JobName theo_read_table.
