To manage an exception in a SQLScript, you can use the SIGNAL and RESIGNAL features, which are SQLScript statements that allow you to raise and handle errors or warnings in your code. The SIGNAL statement allows you to raise a user-defined exception with a specified message and SQLSTATE value. The RESIGNAL statement allows you to propagate an existing exception to the calling procedure or function, or to modify the message or SQLSTATE value of the exception.You can use the SIGNAL and RESIGNAL statements in combination with the BEGIN and END blocks, and the DECLARE and EXIT HANDLER clauses, to define the scope and the action of the exception handling12.

The other options are not correct because they are not SQLScript features that can be used to manage an exception. The DECLARE EXIT HANDLER clause is a SQL feature that allows you to declare a handler for a specific condition or a generic SQLWARNING, SQLEXCEPTION, or NOT FOUND condition. The CREATE EXIT HANDLER statement is not a valid SQL or SQLScript statement at all.Reference:

In application development with XS advanced, the following entities belong to a specific SPACE: Applications and Processes. A SPACE is a logical grouping of applications and processes that share a common purpose and resources. A SPACE can have one or more applications and processes deployed to it, and each application and process can have one or more instances running in the SPACE.A SPACE can also have its own quota, services, routes, and security settings12.

The other two options, Organizations and Users, are not entities that belong to a specific SPACE. An Organization is a logical grouping of SPACES that share a common owner and billing account. An Organization can have one or more SPACES, but a SPACE can only belong to one Organization.An Organization can also have its own quota, roles, and users12. A User is an entity that represents a person or a system that can access the XS advanced platform and perform actions based on the assigned roles and privileges.A User can belong to one or more Organizations and SPACES, and can have different roles and permissions in each of them34.Reference:1:SAP HANA XS Advanced Development (New and Changed) | SAP Help Portal2:SAP HANA XS Advanced, explore the basic tools | SAP3:XS Advanced User Management | SAP Help Portal4:Maintaining Platform Users in XS Advanced | SAP Help Portal

To specify the target currency for currency conversion in calculation views, you can use one of the following methods:

In a column: You can associate the measure with an attribute column that contains the target currency code. For example, if you have a table that stores the sales amount and the currency code for each transaction, you can use the currency code column as the target currency for the sales amount measure.

With an input parameter: You can create an input parameter that allows the user to select or enter the target currency code at runtime. For example, if you want to display the sales amount in different currencies based on the user's preference, you can use an input parameter as the target currency for the sales amount measure.

With a fixed value: You can associate the measure with a fixed currency code that is available in the currency table. For example, if you want to display the sales amount in a single currency, such as USD, you can use a fixed value as the target currency for the sales amount measure.Reference:Associate Measures with Currency,How to perform Currency Conversion in SAP HANA,Implementing Currency Conversion.

According to the SAP HANA Developer Guide, to perform a specific task of an XS advanced application, a user needs to have directly assigned a role collection. A role collection is a set of roles that grant the user the necessary privileges and authorizations to access and use the application. A role collection can be assigned to a user either directly by an administrator, or indirectly by a workflow or a self-service. The other options are incorrect, because:

To have directly assigned a scope is not a way to perform a specific task of an XS advanced application, but a way to limit the access of a user to a subset of resources within an application. A scope is a qualifier that can be added to a role to restrict the user's access to a specific resource, such as a space, an organization, or a service instance. A scope does not grant any privileges or authorizations by itself, but only modifies the existing ones.

To be assigned to an organization is not a way to perform a specific task of an XS advanced application, but a way to group users and resources in a logical unit. An organization is a container that holds spaces, users, applications, and services. An organization can have one or more spaces, which are isolated environments for developing, deploying, and running applications. A user can belong to one or more organizations, but can only perform tasks in the spaces that they are assigned to.

To be assigned to a space is not a way to perform a specific task of an XS advanced application, but a way to access a specific environment for developing, deploying, and running applications. A space is a sub-container within an organization that holds applications and services. A space can have one or more users, who can have different roles and permissions depending on their tasks. A user can belong to one or more spaces within an organization, but can only perform tasks in the spaces that they are assigned to.

You can use declare exit handlers in a SQL Script procedure to handle generic SQL exceptions or specific SQL error codes. An exit handler is a custom handler that defines a block of code to be executed when an exception occurs in the procedure. You can declare an exit handler for a generic SQL exception, which is any error that is raised by the database system, such as syntax errors, constraint violations, or division by zero.You can also declare an exit handler for a specific SQL error code, which is a numeric code that identifies the type and severity of the error, such as 301 for unique constraint violation, or 1299 for no data found12.

The other two options, generic SQL conditions and specific SQL conditions, are not valid arguments for declare exit handlers. A condition is a named exception that can be declared by using a condition variable and optionally associated with an SQL error code. A condition can be used to signal or resignal an exception in the procedure, or to register a continue handler, which is a custom handler that defines a block of code to be executed when an exception occurs, but does not exit the procedure.However, a condition cannot be used to register an exit handler, as the syntax requires an SQL error code or a generic SQL exception12.Reference:1:Exception Handling | SAP Help Portal2:Exception Handling Examples | SAP Help Portal
