• An error is encountered when attempting to use the system field parameters "SY-DATUM" or "SY-TCODE" in the coding BadI implementation (for example) in S/4HANA Cloud Public Edition.
• The error message states: "Access to the field "SY-TCODE" / "SY-DATUM" is not permitted in the current ABAP language version."

1. Attempt to use the system field parameters "SY-TCODE" or "SY-DATUM" in the coding of a BAdI implementation or similar.
2. Encounter the error: "Access to the field "SY-DATUM" is not permitted in the current ABAP language version."

The noted ABAP system fields "SY-TCODE" or "SY-DATUM" are intentionally not available for use in coding. For details on the available system fields please see the help article here. 

This behaviour is intended. For the background on this please check through the following blog for details. 

The restricted ABAP has two targets:

• De-couple custom code from the SAP core by enforcing the exclusive use of white-listed SAP APIs
• Minimize the risk of damages to the system or the data integrity/security
