ABAP - DEVELOPER_KEY_CHECK SAP Function Module
ABAP developers may need to code ABAP in some ABAP reports where some special permissions are required.
In such cases ABAP developers are controlled using DEVELOPER_KEY_CHECK SAP function module.
ABAP programmers can see the above screen for requesting Access key from the ABAP developer.
When the Access key is entered by the ABAP developer, the DEVELOPER_KEY_CHECK function module is called and the validity of the access key is controlled.
Here is the ABAP source code for developer_key_check SAP function module.
