Hey All,

In this blog post, you will learn how to update Alternate Labelling for Functional Locations using SAP Data Services. SAP alternative labeling is a renumbering of functional location, changing the primary key or the definition of an additional view that displays different number schemes.


Picture 1: Example of FLOC Alternate Labelling


This functionality enables you to use a different labelling system for the same hierarchy. For example, the manufacturer company of a technical system can work with labeling system that is different from the one used by a customer.


Requirement: SAP has provided a standard FM ILOX_IFLOS_UPDATE which allows you to update Alternate Labelling for FLOCs.

Pre-requisite: FLOC's should be created in the S/4 HANA or MDG System.

Solution: The standard FM is not a remote enabled one and therefore cannot be used in SAP Data Services Designer. We can create a wrapper around the FM and create a Z function(E.g. ZILOX_IFLOS_UPDATE) as per the ABAP Development standards and then make it remote enabled. You can contact the ABAP developer in your team to create a wrapper around the Standard FM ILOX_IFLOS_UPDATE.

Step 1: Import the Z Function(ZILOX_IFLOS_UPDATE)  in SAP Applications Datastore in SAP Data Services Designer. You can now call this function in a query transform.

For the ZILOX_IFLOS_UPDATE function module, the parameters essential are

Step 2: The Functional Consultant should first test the data using Test Data directory in SE37 and update the Alternate Label for the FLOC using the Z function. If the alternate labelling is getting updated properly in SAP then it should also work in SAP Data Services Designer

  1. Import the ZILOX_IFLOS_UPDATE Function in SAP Datastore.

  2. Get the Input data for the Function in the following format

Step 3: Design the Data flow in SAP Data Services Designer

a. Design the data flow in the below manner

b. In the Query_NRDM query transform, Click on New Function Call

c. Define the Input parameters

d. Select Output parameter as EXCEPTION and AL_RFC_RETCODE. The only disadvantage in this FM is that there are no return parameters. You can ask your ABAP developer to add TPLNR as a output parameter in the FM.

e. Unnest the schema so that it can be outputted to a Target database table

f. Execute the job in Designer by pointing the SAP Datastore configuration to correct S/4 HANA Environment. If the RFC Call is successful, you should receive RFC OK in the AL_RFC_RETCODE, otherwise it will give RFC_EXCEPTION and the corresponding If the Alternate labelling exists, then it will give an exception NEW_STRNO_EXISTS.


I hope this blog is useful for the consultants who are using SAP Data Services as the ETL tool to load the Alternate labelling FLOC data to SAP Target System.
