This topic demonstrates how you can extend the original CDS view with a view extension to provide some additional fields.
Problem:
Our customer asked us to add some fields that are in the “EBAN” table but not in the Manage Purchase Requisition Professional Fiori application(F2229).
Solution:
I created this example to show how those who need to add fields to the S/4HANA Manage Purchase Requisition Professional Fiori App can do so via the CDS extension. We used it in our S/4 Hana(On-Premise) Greenfield Implementation project and we met our customer’s need.
What will you learn?
In this example I will create “CDS Extension” for Purchase Order Professional App to add two fields in the EBAN table.
You’ll learn
- How to create custom CDS extension for Purchase Requisition Item Extensibility View-E_Purchaserequisitionitem.
- How to create custom CDS extension for standart CDS view C_PurchaseReqnHeader
- How to use E_Purchaserequisitionitem in the C_PurchaseReqnHeader .
1– First, we open our application package and C_PurchaseReqnHeader CDS view on Eclipse.
2- Go To C_PurchaseReqnHeader->T_PurchaseReqn ->I_PurchaseReqn->I_PurchaseReqn->I_Purchaserequisitionitem
In the I_Purchaserequisitionitem CDS View you can see standart extension view E_Purchaserequisitionitem.
3- This view is using the “EBAN” table. We will add the fields we want to get from the EBAN table by making a standard view extension to this view.
Right Click to E_Purchaserequisitionitem.and choose New Data Definition.
4- I add two new fields to this extension view then activate it.
Created by- ERNAM
Request Date- BADAT
5– Now we can use these fields in the main C_PurchaseReqnHeader view.
I create a extend view for C_PurchaseReqnHeader as in point 3 and activate it.
After all of these, you can see your new fields in “Manage Purchase Requisition Professional Fiori Application(F2229).”
