The executable rsd_time_tct_mreadclass_check.exe (or its internal ABAP program equivalent) validates the consistency of Time-Consistent (TCT) Master Data Read Classes inside the technical content of the Business Warehouse layer. When the routine fails, it stalls the automated initial setup or system conversion sequence. Common Root Causes
If the elapsed time is within an expected, very low threshold, the program continues normally. However, if the difference is abnormally large—often caused by a debugger "stepping" through each instruction—the program knows it is being debugged. In such a case, it will trigger its anti-tamper response, which might include terminating itself, corrupting data, or, as you’ve encountered, displaying an error message and halting execution.

: Ensure that all initial setup steps for SAP BW on S/4HANA have been completed before running the validation task list.
This is the first and most likely solution. If the rsdtimetctmreadclasscheck.exe file is stored in a shared folder between your host and virtual machine (e.g., a folder like /mnt/hgfs/ in VMware or a mapped network drive in VirtualBox), you must move it.
If the automated check fails, it usually points to an anomaly in the time-dependent master data read classes. You can fix this manually in the SAP GUI: SAP GUI -> Transaction RSD1 -> InfoObject Maintenance Go to transaction .
The error message "Error executing RSDTimeCTMReadClassCheck.exe 2021" typically occurs when the system fails to execute the RSDTimeCTMReadClassCheck.exe file, which is a legitimate executable file associated with certain software applications. This file is responsible for reading and checking class information, and its failure to execute can lead to various issues, including: When the routine fails, it stalls the automated
