I was working on customizing SAP Business Application Studio and implementing some specific logic and modifications.

i dont know if i need to create an Adaptation Project in SAP Business Application Studio and then implement the extension using Visual Editor or create an other option when created the project.

1. Filtering Account Assignment Category:

   • I want to implement logic based on conditions like BSEG-BLART='WE' or BSEG-BLART='WA', BSEG-BSCHL≠'96', and BSEG-HKONT='account entered'.
   • it's possible to implement this logic using an adaptation project. I can utilize the Visual Editor to define these filter conditions based on the fields you've mentioned, how can i Add this login in the new filter?

2. Adding Additional Columns:

• To add additional columns within the standard, I have a couple of options:
  • Create an adaptation project: This would involve extending the existing application with additional fields in the table or modifying the existing ones.
  • Copy the existing project with program /UI5/UI5_REPOSITORY_LOAD: This approach involves copying the existing project and then making modifications as needed. This can be more complex but gives you greater control over the changes.

1. Regarding the backend steps:

   • For creating an adaptation project:

     • If you're adding fields that require changes in the backend, you might need to extend the existing OData service or create a new one using SAP Gateway Service Builder (transaction SEGW).
     • After modifying the OData service, you'll need to publish the changes in Eclipse.

   • For copying the existing project:

     • If the modifications require changes in the backend, you'll likely need to copy the relevant CDS views and/or OData services and then adjust them as necessary.
     • After making changes, you'll also need to publish the modified artifacts in Eclipse.

what is the step by step

I downloaded and uploaded the application, modified the annotations and the manifest, and encountered the following error. Is this the right path?

are there any blog that help me to make the rigth decision and the step?

Thanks
