GET PARAMETER

Quick Reference

Syntax

GET PARAMETER ID pid FIELD dobj.

Effect

This statement sets the content of the data object dobj to the content of the SPA/GPA parameter specified in pid in the user memory. The ID pid must be a flat character-like field that contains no more than 20 characters and does not consist solely of blanks. The field is case-sensitive. The binary content of the SPA/GPA parameter is passed to dobj without being converted. The following can be specified for dobj:

The statement GET PARAMETER does not access the user memory directly. Instead, it accesses a local mapping of the SPA/GPA parameter in the program memory, which is loaded when rolled in and saved in the user memory when rolled out (see SPA/GPA Parameters and ABAP Programs). If the SPA/GPA parameter specified in pid does not yet exist in the user memory for the current user, the data object dobj is initialized and sy-subrc is set to 4.

A program can only read those SPA/GPA parameters for which there is a name in the table TPARA. If it is known statically that an ID pid is not in the database table TPARA, the extended program check reports an error.

System Fields

sy-subrc Meaning
0 The SPA/GPA parameter specified in pid exists for the current user in the user memory and its value was passed to the target field.
4 The SPA/GPA parameter specified in pid does not exist for the current user in the user memory.

Notes

Example

In this example, the current value of the SPA/GPA parameter RID is read from the user memory to the data object prog. In the dynpros in ABAP Workbench, this parameter is associated with the input fields for a program name. When an ABAP Workbench tool in which an ABAP program is processed, is first called, the parameter is created in the event PAI and assigned the name of the program specified there. If, in the same user session, no dynpro is processed that sets the parameter RID and no corresponding SET PARAMETER statement was executed beforehand, RID is not found in the user memory.
