How to Create a Custom Validation from Fiori App Manage Substitution and Validation Rules

As we are moving to Fiori first yet cloud ready approach for any development, why restrict us to GGB0 or GGB1 for creating validation or substitution rules?

We can utilize the Fiori application - Manage Substitution and Validation Rules to create the rules which will be applied to all the standard processes such as standard interfaces, GUI T-codes and managing standard processes in custom program.

In this blog, we will create a custom-defined function in the validation rule on asset creation or modification done through the Fiori app - ‘Manage Fixed Assets’. The rule will validate against the supplier assigned to the asset master record.

ABAP Restful Application Programming: Custom actions => Merge Draft entities into Active and switch to display mode

Introduction:

In this blog post, I will explain about “Custom actions” that can merge draft entities into Active and switch to display mode. An action in RAP is a non-standard modifying operation that is part of the business logic. The standard use case of an action is to change specific fields of a business object entity.

Problem statement:

In General, MODIFY ENTITIES can be used to change the required fields in an entity. That means, Active instance remains as active and Draft instance remains as Draft. But some business requirements expect us to convert those draft instances into active instances.
