How to find the odata errors in SAP S/4HANA

by

Loading

Check OData Error Logs in /IWFND/ERROR_LOG

The primary location for checking OData service errors is the transaction /IWFND/ERROR_LOG.

  • Steps:
    1. Execute the transaction /IWFND/ERROR_LOG in the SAP GUI.
    2. Use filters such as User, Date/Time, or Service to narrow down the results.
    3. Check the error details for further analysis.
  • Error Analysis:
    • Analyze the error codes and messages.
    • Inspect the stack trace for technical details.
    • Often includes information about missing authorizations, incorrect URIs, or payload issues.

Advanced Variant Configuration screen does not open in classic SAPGUI transactions

by

The Advanced Variant Configuration screen does not open in classic SAPGUI transactions (e.g. Sales Order processing) and shows an error page or an empty screen or an error message that some requests were not successful in case the S/4HANA embedded Fiori deployment option is used, which means S/4HANA backend and Fiori frontend server system are the same.

Another issue is that a logon page comes up in SAPGUI for Windows when opening the Advanced Variant Configuration screen in case the S/4HANA embedded Fiori deployment option is used.

The reason for the issue in the Advanced Variant Configuration screen is that an origin URL parameter is added to the OData requests sent to the SAP Gateway system, which is prohibited by SAP Gateway in the Co-Deployment scenario.

The logon page issue happens because in SAPGUI for Windows, the SSO logon cannot be established the same way as when accessing the system via Fiori Launchpad and embedded SAPGUI for HTML; instead, a ticket-based logon using special capabilities of the SAPGUI HTML Viewer control is used.

Advance Variant Configuration(AVC) & VCH_HL_AFL_CHECK

⚡Advance Variant Configuration(AVC) &VCH_HL_AFL_CHECK⚡

🎯  As we know the AVC has to be installed after the S4 Hana has been installed. This can be part of your upgrade or even for new installation

🎯 It is always important to evaluate if all the Technical Pre-Requisites are completed correctly

🎯 This is completely as Technical task for validation but still it is good for the Functional consultants also to be aware of this Pre-Requisites.

🎯 SAP has provided a standard report -VCH_HL_AFL_CHECK which will help you to execute and confirm the same.

🎯 There are parameters which are more technical but the important part is you should be getting a  message -“Procedure Called Successfully” in Green Highlighted color. This confirms that the technical pre-requisites are installed correctly.

Material and Class Linkage Details-1

by

In case if you are looking for solution of extracting the assignment of the Class data in SAP Using Standard Transaction, then below will be helpufl

Option 1:  Use the Standard Code  – CL6B – Object List 

This gives you List of Classes and the objects ( materials) assigned to it

Option 2:  Use the Standard Code  – CL6BN – Object List 

This gives you List of Classes and the objects ( materials) assigned to it in ALV Format.

 

 

The only challenge is in case if you need analzyse, the output when we save in exce l is not user friendly as it comes in a nested structure.

To avoid this we should try to extract the data from the SAP tables, will post as a separate thread.

Sales order Creation with Variant Configuration

by
The creation of sales order with variant configuration characteristics will be a little tricky one.
we have to use the below  Function module(FM) –
For Creation : SD_SALESDOCUMENT_CREATE
For Changes: SD_SALESDOCUMENT_CHANGE
 
one of the advantage of using this FM is that this will support all document types like Sales order, Scheduling agreements, Customer independent Requirements.

In the following section we will see the usage of this FM to create a simple Customer Independent requirement (MD81) with the variant configuration values passed on to the same.The below are the fM structure you need to work with

 

ORDER_HEADER_IN
ORDER_ITEMS_IN
SALES_SCHEDULES_IN
SALES_CFGS_REF

Variant Configuration – ALE Message Types

by

If you are working in a Variant configuration environment, then one of the best practices to transfer the VC – Master data between the Clients / Box is to use the ALE Methods.

The below list of message types can be a quick reference for Inward / Outward.

Outward:
MATMAS – Material master
BOMMAT -BOMs: Material BOM
CHRMAS -Class system: Characteristics master
CLFMAS -Class system: Classification master
CLSMAS -Class system: Classes master
CNPMAS -Configuration profile
DEPNET -DEPNET
ECMMAS-Engineering Change Management
KNOMAS -Global object dependencies

UPSMAS -ALE Distribution Unit (MASTER)
VFNMAS -Variant function
VTAMAS -Structure of the variant table
VTMMAS -Contents of variant table

INWARD:

MATMAS -MATM -Material Master
BOMMAT -BOMM -BOMs: Material BOM
CHRMAS -CHRM -Class system: Characteristics master
CLFMAS -CLFM -Class system: Classification master
CLSMAS -CLSM -Class system: Classes master
CNPMAS -CNPM -Configuration profile
DEPNET -DEPN -DEPNET
ECMMAS -ECMM -Engineering Change Management
KNOMAS -KNOM -Global object dependencies

UPSMAS -UPSM -ALE Distribution Unit (MASTER)
VFNMAS -VFNM -Variant function
VTAMAS -VTMAM Structure of variant table
VTMMAS -Contents of variant table

Variant Configuration – Formal Parameter not valid

by

Error Message: E28086 Formal parameter MATERIAL_XX not valid for: ZVC_XXX_YYY (Line 1)

Generally to read a value from the table we will define the C’stics from table and the C’stics from the class.

LHS = RHS

On LHS= we will be giving the Table Characteristics value

and on RHS = We will be giving the value from the Variant class.

In case if you are maintaining a DB link to the VC table, then more attention to be given to the C’stics when procedure is created.

Here you should ensure that we are giving the C’stic value from the Class and not the table. If we make any mistake then the Error E28086 bound to Happen.
