WS aka Web Scripts (Attended RPA for SAP) / Determining User Count based on SAP Role
« on: February 01, 2024, 03:54:47 PM »
User Count and Details based on specific user role

For role based customization using Liquid UI, Liquid UI needs to be enabled for a pre-determined role
Example: Z_LIQUIDUI

Use Transaction SE16
Table: AGR_USERS
Role: Z_LIQUIDUI  (in this example)
Click 'Execute'

This will give all the users who has Z_LIQUIDUI role assigned.

This can be used to determine the user count for Liquid UI usage.

WS aka Web Scripts (Attended RPA for SAP) / RFC CALL: /GUIXT/SELECT
« on: January 17, 2024, 03:52:03 PM »
This article describes the details on how to call /GUIXT/SELECT , RFC enabled function module in SAP using Liquid UI

Calling /GUIXT/SELECT Function Module

Things to pay attention to:

1. FUNCTION NAME SHOULD BE UPPERCASE IN CALL STATEMENT
2. PARAMETER NAMES SHOULD BE UPPERCASE IN CALL STATEMENT
3. WIDTH FOR OUTPUT IS 2X THE TOTAL CHAR COUNT (DOUBLE BYTE UNICODE)
4. IF TABLE OUTPUT IS CHAR (EXAMPLE: CHAR8000), THEN PASS DEFINED STRUCTURE TO RETRIEVE DATA. 
5. STRUCTURE DETAILS TO BE DETERMINED BASED ON WHAT THE OUTPUT IS DERIVED FROM
(EXAMPLE: TABLE, CHECK SE11 FOR TABLE STRUCTURE)
6. THE STRUCTURE NEEDS TO BE DEFINED TILL THE LAST FIELD DATA THAT NEEDS TO BE RETRIEVED

// Sample script: Easy Access Screen


// SAPLSMTR_NAVIGATION.E0100.sjs

del("X[IMAGE_CONTAINER]");

pushbutton([1,1],"RFC Test","?",{"size":[1,20], "process":fnTestRFC});

function fnTestRFC() {
   var r = [];

   var z_KNA_DETAILS_E = {
      name:'CHAR8000_D',
      components:[
            { name:'MANDT',      length:3,      decimalpl:0,    type:'C' },                                 //Order Number
            { name:'KUNNR',      length:10,      decimalpl:0,    type:'C' },                                 //Order Type
            { name:'LAND1',      length:3,      decimalpl:0,    type:'C' },                                 //Maintenance Planning Plant
            { name:'NAME1',      length:35,      decimalpl:0,    type:'C' }                                 //Business Area
      ]
   }

   //set("V[z_flds]","MANDT,KUNNR,LAND1,NAME1");
   set("V[z_flds]","KUNNR,NAME1");

   println("Calling RFC.......");

   var rfcResult = call("/GUIXT/SELECT",{"in.TABLE":"KNA1","in.FIELDS":"&V[z_flds]", "in.CONDITION":"ORT01 = 'HEIDELBERG'", "table.RESULTTABLE(width:16000,type:z_KNA_DETAILS_E)":"r","verbose":true});

   println("rfcResult.rc:"+rfcResult.rfc_rc+":");
   println("rfcResult.key:"+rfcResult.key+":");
   println("rfcResult.exception:"+rfcResult.exception+":");
   println("Total Records:"+r.length+":");

   for(i=0;i<r.length;i++) {
      println("i:"+i+":"+r["KUNNR"]+":"+r["NAME1"]+":");
   }
}

WS aka Web Scripts (Attended RPA for SAP) / Liquid UI Software and Script Deployment
« on: February 03, 2022, 09:52:11 AM »
Requirements:
Managing software installation and scripts for user's across multiple locations

Pre-Requisites:
Liquid UI Desktop (Local user software deployment), or Liquid UI Server (Central Software Deployment)

Scenario 1: 
The scripts are common across all locations from where user is required to access the solution.
[One set of scripts for all locations]

Preferred Solution:
- Deploy software centrally using Liquid UI Server
- One Configuration file for all users across location
- Depending on the number of users, install single Liquid UI Server or multiple Liquid UI Servers and load balance them using a 3rd party hardware load balancer.
  Refer to Server Sizing Requirements: https://www.guixt.com/knowledge_base/content/18/310/en/32-server-sizing-requirements.html
- Deploy the scripts either locally on the Liquid UI Server or SAP Web Repository
  Refer to Script Deployment Options: http://www.guixt.com/forum/index.php/topic,317.msg321.html#msg321
- Set up SAPGUI Connection to Liquid UI Server for all users.  ** No Need to Activate GuiXT" on end user's machine

Scenario 2: 
The scripts are different for individual locations from where user is required to access the solution.
[Multiple et of scripts for all locations]

Preferred Solution:
- Deploy software centrally using Liquid UI Server for each location
- Separate Liquid UI Configuration file or each location identifying the script location
- Depending on the number of users at each location, install single Liquid UI Server or multiple Liquid UI Servers and load balance them using a 3rd party hardware load balancer.
  Refer to Server Sizing Requirements: https://www.guixt.com/knowledge_base/content/18/310/en/32-server-sizing-requirements.html
- Deploy the scripts either locally on the Liquid UI Server or SAP Web Repository
  Refer to Script Deployment Options: http://www.guixt.com/forum/index.php/topic,317.msg321.html#msg321
- Set up separate SAPGUI Connection to Liquid UI Server for users specific to their location .  ** No Need to Activate GuiXT" on end user's machine
  This will require different SAPGUI connection details based on where the user is located.

Alternatively:
- User's can be assigned different role based on their location, and a usercatalog can be setup which is role specific
- The usercatalog allows specification of groups and directories based on groups
- This way solution can be deployed using Scenario 1.
- Refer to article for using usercatalog: http://www.guixt.com/forum/index.php/topic,152.msg156.html#msg156


With Liquid UI Server deployment approach 
  a. Both software and configuration can be maintained centrally, and no software files and associated configuration files needs to be
      deployed to each individual users.
  b. Scripts can stay either centrally on Liquid UI Server folder or in SAP Web Repository depending on customer's preference.
  c. Mobile ready, to leverage the solution on iOS, Android and Windows CE based devices



With Liquid UI Desktop Deployment Approach
  a. Software needs to be installed on each individual user's machine.
  b. Software configuration files needs to be installed on each individual user's machine.
  c. Software upgrade will require each user's machine to be updated.
  d. If scripts are stored using network share location, then their is additional dependency on the network share, if the share is not accessible, the Liquid UI Solution is not accessible

Note:
With both Desktop and Server Deployment, there are multiple options to deploy the scripts.

Mobile Products (Android, iOS and CE) / License Error Liquid UI for Windows CE connection to S/4 HANA environment
« on: January 13, 2022, 11:48:03 AM »
Issue:
While connecting to S/4 HANA environment using Liquid UI for Windows Mobile/CE, even though a valid license exist, a license error popup shows up on the UI

Reason:
Launching system>status from the menu bar did not launch the usual, expected system status screen.
Instead, it displayed avery restricted subset of the information under the header ?Repository Data? ?

Resolution:
For solution see SAP Note 2658772.

SAP_BASIS version 7.53 has now introduced a new authorization check on system>status.
The contents of this popup is now restricted through the authorization object S_SYS_INFO.
There was no restriction on this in the earlier versions.
In order to get back the unrestricted view, you will need to create a new role containing the above object, or add it to an existing role, with the below field values ?

ACTVT:
03 (Display)

INFO:
USER (to view the ?user data? section)
SYSTEM (to view the ?SAP system data? section)
HOST (to view the ?host data? section)
DB (to view the ?database data? section)
KERNEL (to access the kernel information)

WS aka Web Scripts (Attended RPA for SAP) / How to develop scripts when using Liquid UI Server
« on: January 12, 2022, 10:26:25 AM »
The purpose of Liquid UI Server is for central software deployment.  No software footprint on user's local machine.

The scripts are developed on developer's desktop using local SAPGUI and local software installation
This way the scripts are accessible to the developer on their own machine, and Liquid UI console window is available for the developer to debug
any issues.  This is the preferred method in a multi developer environment.

The developed scripts are then then deployed centrally using web repository, or network share.

Also when deploying the software centrally using Liquid UI Server, the production and non production environment shoule be executed on different machines
to prevent any disruptions in production environment usage

Liquid UI Server for development can also be executed in console mode as and when need,
which can provide access to the console window for additional debugging at the Server Level

Liquid UI Server aka GuiXT Server / LiquidUI SAP SSO Communication Flow (iOS and Android Clients)
« on: December 01, 2021, 11:44:54 AM »
LiquidUI - SAP NetWeaver AS ABAP SSO
Workflow for iOS and Android Clients

SAP Communication Channels


See Diagram in attached file, which shows the connection from Liquid UI iOS-Android Clients to LUI Server secured using TLS 1.3


From LUI Server to SAP ECC, connection is established as SAP's trusted server SSO, using SAP's digitally signed Logon Ticket.

On both ends of the Server the connections are secured.  One via TLS 1.3 and the other via Trusted Server Logon Ticket


Trusted Server Connection to SAP ECC is compressed, and the SAP ECC Kernel does not support further encryption.  This SAP Native protocol is not https traffic.
Synactive recommends the LUI server be placed close to the SAP ERP Server to the maximize the optimizing feature as well as to ensure security.
Furthermore, the trust relationship established between LUI Server and SAP ECC ensures that no 3rd party can access this Trusted Server Channel.
Trusted Server Connection is needed not only in the Desktop mode, but it is a necessity in the Mobile environment, where there is no Kerberos SSO.  Connection to LUI Server from the Mobile device is protected by TLS 1.3.
