SAP B1 HANA is a powerful enterprise resource planning (ERP) software that provides comprehensive business functionality to companies of all sizes. One of the key areas of functionality in SAP B1 HANA is table service, which allows users to access and manipulate data in the system. There are four main types of table service in SAP B1 HANA:

1. Read Table Service

The read table service allows users to retrieve data from tables in the system. This service is typically used to display data in reports, forms, and other user interfaces. The read table service can be used to retrieve data from both base tables and view tables.

2. Insert Table Service

The insert table service allows users to add new rows to tables in the system. This service is typically used to create new records in the system, such as new customer records, new sales orders, or new inventory items. The insert table service can be used to insert data into both base tables and view tables.

3. Update Table Service

The update table service allows users to modify existing rows in tables in the system. This service is typically used to update records in the system, such as updating customer contact information, changing sales order quantities, or adjusting inventory levels. The update table service can be used to update data in both base tables and view tables.

4. Delete Table Service

The delete table service allows users to remove rows from tables in the system. This service is typically used to delete records from the system, such as deleting customer records, sales orders, or inventory items. The delete table service can be used to delete data from both base tables and view tables.

How to Use Table Service in SAP B1 HANA

Table service is used in SAP B1 HANA through the use of the OPEN DATASET statement. The OPEN DATASET statement opens a connection to a table in the system and allows the user to perform read, insert, update, or delete operations on the table.

For example, the following code opens a connection to the Customers table in the system and retrieves all of the customers in the table:


OPEN DATASET customers FOR READ.
DO.
  READ customers.
  IF customers-customer_id IS INITIAL.
    EXIT.
  ENDIF.
  "Process the customer record.
ENDDO.
CLOSE DATASET customers.

The following code opens a connection to the Customers table in the system and inserts a new customer into the table:


OPEN DATASET customers FOR INSERTION.
INSERT customers.
  customer_id = 'C001'.
  customer_name = 'Acme Corporation'.
  customer_address = '123 Main Street'.
ENDINSERT.
CLOSE DATASET customers.

Table service is a powerful tool that can be used to access and manipulate data in SAP B1 HANA. By understanding the different types of table service available, users can effectively use this service to meet their business needs.
