A typical data retrieval system may therefore consist of any of the three mechanisms implemented in the different environments. You run the automated system in the SAP development environment. You then finally move this to the SAP production environment. This implementation is recommended by Oracle, as it automates and simplifies the data retrieval task.
Depending on the access rights to the development, test, and production environments, you implement any one of the data retrieval mechanisms in each of the environments. The following sections provide details of the tasks involved in retrieving data from an SAP system:. Different sets of files are required depending on whether you are working on a Windows or a UNIX system.
You must copy librfc To find this location, click MyComputer , Properties , and then click Advanced. Next click Environment Variables , and under System variables, check the locations specified for the variable Path.
You can copy the librfc Table Required Files for Windows. The most common errors while connecting to the SAP system are listed in Table :. Select the module status and optionally also provide a description. Click Next. When you set the connection information, you can choose the connection types described in the subsequent sections. A remote function call enables you to call a function module on a remote system.
Enter the connection information in the appropriate fields. The fields displayed on this page depend on the connection type you choose. You must obtain the connection information for your SAP application server from the system administrator before you can complete this step. This must be provided by the SAP system administrator. Client: The SAP client number. This name is supplied by the SAP system administrator.
If you select DE, the description text is displayed in German and all other text is displayed in English. This user must have access rights to copy the data file using FTP. For systems where the FTP directory structure is identical to the operating system directory structure, this field can be left blank.
For systems where the file system directory structure is mapped to the FTP directory structure, enter the FTP directory path that is mapped to the staging file directory in the file system directory structure. Click Test Connection to verify that the connection information you provided is correct. This wizard enables you to filter the SAP tables to import, verify those tables, and reimport them.
You can import metadata for transparent tables, cluster tables, or pool tables. Right-click the SAP source module into which you want to import metadata and select Import. You can filter objects to import by business domain or by text strings. Select a filtering method and click Next.
The Import Metadata wizard displays the Loading Progress dialog box while it is retrieving the business domains. Use the Business Domain Hierarchy dialog box to select the SAP business domains that contain the metadata tables you want to import. Select a folder and click Show Tables to view the tables available in a business domain. The Import Metadata Wizard displays a list of tables in the selected business domain in the Folder dialog box. Some business domains can contain more than tables.
Importing such a large amount of metadata can take time, depending on the network connection speed and the processing power of the source and target systems. Select Text String, where object and use the Name matches or Description matches entry field to enter a string and obtain matching tables from the SAP data source. The Description matches field is case sensitive, the Name matches field is not. You can also search for tables by their names.
Specify the number of tables you want to import in the Maximum number of objects displayed field. The Object Selection page contains a description of the tables and enables you to select the tables you want to import into the SAP module.
The Import Metadata Wizard also enables you to choose whether you want to import tables with foreign key relationships for each table that you choose to import. You can select one of the following:. One Level : Import the tables in the Selected list and any tables linked to them directly through a foreign key relationship.
All Levels : Import the tables in the Selected list and all tables linked to them through foreign key relationships. The wizard imports the definitions for the selected tables from the SAP application server, stores them in the SAP source module, and then displays the Summary and Import page. You can edit the descriptions for each table by selecting the Description field and entering a new description. Review the information about the Summary and Import page and click Finish.
The time it takes to import the SAP metadata into the workspace depends on the size and number of tables and the connection between the SAP application server and the workspace.
It is a best practice to import small batches of tables to allow better performance. When the import completes, the Import Results dialog box displays. Click OK to finish importing metadata. Before starting the import, the wizard checks the source for tables with the same name as those you are importing. The tables that have been imported appear in bold in the Object Selection page. On the Summary and Import page, the Action column indicates that these tables are reimported.
The wizard then activates the Advanced Synchronize Options button so that you can control the reimport options. With SAP tables, you cannot view the data after you import the metadata from these tables. However, you can get good insight about the data that is stored in the tables by viewing the "Column Descriptions" and the "Constraints Details".
You can view the column description of each of the columns in a table. This is valuable because the column names in SAP can be nondescriptive, and difficult to interpret if you have not previously seen the data in the table. To view the descriptions, double-click the table to open the data object editor for the table, and then click the Columns editor.
The description for the columns of the table are visible as shown in Figure The other benefit of the data object editor is that you can get information about the primary and foreign keys within the table. To view the key constraints, click the Constraints editor. Creating a mapping with SAP tables is similar to creating mappings with other database objects.
However, there are restrictions on the operators that can be used in the mapping. You can only use table, filter, joiner, and mapping input parameter mapping operators in a mapping containing SAP tables.
A typical SAP extraction mapping consists of one or more SAP source tables transparent, cluster, or pooled , one or more filter or joiner operators, and a non-SAP target table typically an Oracle table to store the imported data. In this mapping, the input parameter holds a date value, and the data from table BKPF is filtered based on this date.
Because this is defined as an input parameter, you can enter a value for the date when the mapping is run. The joiner operator enables you to join data from multiple tables, and the combined data set is stored in a staging table. The following table provides an explanation of all the attributes and their significance. Under the Attributes section, provide the following values as shown in the figure below: Type : Executable program Status : Test Program Application : Unknown application 5.
Click the Save button when finished. Therefore, the data transfer between the screen and the program is handled automatically. This should show you the output or List screen, as shown here: Learn More. Latest Blogs. Read More. Subscribe to our blog! Get notified about future blog updates.
