How to replicate end-routines and function modules from SAP BW4H to SAP Datasphere?

[rohan555_pj]

We have SAP ADSO created in SAP BW4H extracted from S4H. Some of the Dimensions have routines and standard function modules in end-routines and field level routines. How do we replicate this in SAP DS. Is there any migration tool or any blogs or any methods to replicate the SAP Standard function modules and custom ABAP routines in SAP DS ? 

For example, Convert date to FY Period. we have a standard FM where we can use in BW4H to convert date to FYP. How can we replicate that in SAP DS if we are building a new flow in SAP DS. Please advise.

Thanks

On DSP there is no ABAP possible.
However if you are using BW-Bridge you sill can use ABAP but there are some restrictions for the BW and ABAP functionalitys.
(Like you use lose the OLAP Enginge so the Query with the Customer Exit's ect.)

This is a good blog about the BW - Bridge:
https://community.sap.com/t5/technology-blogs-by-sap/sap-datasphere-sap-bw-bridge-overview-and-techn...
Within this blog restrictions are listed and there is an offical Note from SAP:

The DSP is "nothing more than an overlay" that supports SQL Implementations on top of the SAP HANA DB.
(Some Exceptions are there, like sending e-Mails after Task Chains, but it's not that flexibel and Powerfull like a BW is, e.g. schedule a ABAP Programm in a ProccessChain with in the Programm call REST API do your logic and at the send E-Mails to a Userlist that own's a specific Role )
I think it's best if you read the blog about the BW Bridge.
( You will get a feeling what is possible within the DSP itself by just checking what the migration tool is capable to convert ;), maybe you should think of getting a BW-Bridge to keep your BW Implemenations )

Hi @rohan555_pj,

As far as I know, there are no migration tools for the dimension routines that are on the ABAP platform. Check out this question Options of routines to implement logic in Datasphere and  @XaviPolo's answer.

Thanks,

Yep thanks for the update. We need to code manually and no shortcut unfortunately.
