What is referential integrity in sap bw?

Hi, Referential integrity is the property that guarantees that values from one column depend on values from another column. This property is enforced through integrity constraints. If you set this flag a check for referential integrity is performed for this InfoObject, against the master data table or ODS object.

What is SAP integrity?

Data integrity means that the data is valid (correct and accurate) and the relational structure of the database is intact. Referential integrity constraints enforce the relational structure of the database. These rules maintain the consistency of data between tables.

What is Sid in SAP BI?

A Surrogate ID (SID) is an integer number which is assigned to each master data value. These SIDs are stored in separate tables called SID tables. For each value entering the active data table of the DSO, SAP BW will check the SID table of the InfoObject into which the value will be written.

What is database integrity in ABAP?

Relational integrity refers to the observation of the integrity rules governing the relational model. Since data modeling in the AS ABAP is based on the relational data model, these rules must be observed. They include: Primary key integrity. Each database object must be uniquely identified by a primary key.

What is referential integrity in SAP HANA?

If you set this flag a check for referential integrity is performed for this InfoObject, against the master data table or ODS object.

How check for referential integrity is possible?

With error handling functionality referential integrity can be checked within an InfoObject against the master data tables or Datastore Objects on a communication structure level. Referential Integrity check fails, Package set to turn red. It could be set to green.

What is referential integrity?

Referential integrity refers to the relationship between tables. Because each table in a database must have a primary key, this primary key can appear in other tables because of its relationship to data within those tables. Referential integrity is the logical dependency of a foreign key on a primary key.

How does SAP HANA validate referential integrity?

We can define on which Object the Referential Integrity Check is to be performed on the InfoObject itself. Setup in the InfoObject Maintenance screen under Master Data/texts tab.
