Suggested update:

    char              AppName[OS_MAX_API_NAME] = {""};
    CFE_SB_BufferD_t *BufDscPtr;
    CFE_SB_Buffer_t * BufPtr;
    CFE_Status_t      Status;

    AppId     = CFE_ES_APPID_UNDEFINED;
    BufDscPtr = NULL;
    BufPtr    = NULL;

    Status = CFE_ES_GetAppID(&AppId);

    if (MsgSize > CFE_MISSION_SB_MAX_SB_MSG_SIZE)
    {
        CFE_ES_GetAppName(AppName, AppId, sizeof(AppName));
        CFE_ES_WriteToSysLog("%s %s: Failed, requested size %ld larger than allowed %d\n",
                             AppName, __func__, MsgSize, CFE_MISSION_SB_MAX_SB_MSG_SIZE);
        return NULL;
    }
