Can not extend lagacy sap ui5 app in VSCode ?

[nadimmabrouk]

Hello Experts;

I'm trying to extend sapui5 standar App "Approve Purchase Orders - F0402 " in VScode for an ECC system . But the following error is show up 

My question is: if I switch to BAS, will I face the same issue again? Does BAS guarantee the same functionality as SAP Web IDE for extending legacy SAP apps as before?

Regards

Nadim

Hi Nadim,

Extending a legacy SAP Fiori application is supported in SAP Business Application Studio, with most of the functionality that is available in SAP Web IDE Full-Stack. It is also possible to migrate an SAPUI5 extension project from SAP Web IDE into Business Application Studio dev space and continue working with it.

You can find the official documentation with all the specific details here: 

• https://help.sap.com/docs/bas/developing-sap-fiori-app-in-sap-business-application-studio/adaptation...
• https://help.sap.com/docs/bas/developing-sap-fiori-app-in-sap-business-application-studio/migration

Note that for legacy applications that are supported for extension via an Adaptation project, this one will be created (and not an SAPUI5 extension project). This is according to SAP best practices.

In case you don't already have a license to SAP Business Application Studio, you can try this out (not for production usage of course) in SAP BTP Trial or using an SAP BTP free tier account. See here: https://help.sap.com/docs/bas/sap-business-application-studio/getting-started

Thanks,
Rotem
