Oracle flat file loading

The application requires a fixed naming convention for the. These names are used to automatically identify the entity it contains and implies a corresponding. Ensure that the transactional data is uploaded to the planning server using either legacy systems directly or an Oracle EBS application.

To avoid double counting, do not upload the same transaction data to both Legacy and EBS instances. For example, a sales order should not be uploaded using both EBS and Legacy instances. Before you can upload transactional data to an VCP destination instance, you must format your data. An Excel template is provided to help you prototype or inspect the. Usually, implementations loading ERP data via flat.

Use the ExcelLoad. If you are importing. Delimiter: Used internally to separate different columns in the. It opens a window to modify the values and select an action:. Note: Once you enter these values, you do not need to enter them again. The Load Transaction Data program loads the transaction data through flat files into staging tables.

Load Transaction Data accepts parameter values including the path for control and data files. The Pre-Process Transaction Data program preprocesses the transaction data and generates ids. Pre-Process Transaction Data enables you to specify the instance in which you want to load the transaction data. Enter the required information and the file names for all the data files that you want to upload.

Specify the maximum amount of time you would like to allocate to the concurrent program in the Time Out Duration field. You can access these files from within the repository at any time. The wizards load and unload table data only.

They do not load or unload other kinds of schema objects. You can load and unload to and from your own schema only. This is also true for users with administrator privileges. Suppose also that you want to create a tab-delimited text file, and you want to save the data in a file called regions.

See "Accessing the Database Home Page" for information on getting logged in. The Unload to Text page appears, showing the Schema wizard step. This wizard step displays a Schema list, in which HR is selected. Because you can unload from your own schema only, you cannot change this selection. Select all columns by clicking and dragging or by clicking and shift-clicking, and then click Next. You can also select a subset of columns.

Deselected columns are excluded from the unload operation. You can use any character as the delimiter. This causes the first row unloaded to be the column names, rather than the first row of data. You can use this first row to set column names when you load. A Save As window appears, with the file name regions.

Depending on your browser, another window may precede the Save As window, asking you if you want to save or open the file. If so, take the option to save the file to disk. Optional Open the regions. Suppose also that you previously unloaded region data from a desktop database system into a tab-delimited text file named regions.

You want to use the region number field in each record as a business key but not as the primary key, and you therefore decide to have the Load wizard generate a numeric primary key for each loaded record. To log out first, click the Logout button at the upper right-hand corner of the page. See "Creating Users" for instructions. Under the Load To heading, select New table , and under the Load From heading, select Upload file comma separated or tab delimited.

Click Browse , select the regions. Next to the Primary Key Population label, select Generated from a new sequence. The load proceeds, and when it is complete, the Text Data Load Repository page appears, showing the regions. Check the load status by looking under the Succeeded and Failed columns for the regions.

The numbers in these columns indicate the number of rows that were successfully loaded or that caused an error. A particular datafile can be in fixed record format, variable record format, or stream record format the default.

The log file contains a detailed summary of the load, including a description of any errors that occurred during the load. The discard file contains records that were filtered out of the load because they did not match any reco rd-selection criteria specified in the control file. Conventional Path. A conventional path load is the default loading method. This method can sometimes be slower than other methods because extra overhead is added as SQL statements are generated, passed to Oracle, and executed.

Direct Path. A direct path load does not compete with other users for database resources. It eliminates much of the Oracle database overhead by formatting Oracle data blocks and writing them directly to the database files, bypassing much of the data processing that normally takes place. Therefore, a direct path load can usually load data faster than conventional path. However, there are several restrictions on direct path loads that may require you to use a conventional path load. For example, direct path load cannot be used on clustered tables or on tables for which there are transactions pending.

See Oracle Database Utilities for a complete discussion of situations in which direct path load should and should not be used. External Tables. An external table load creates an external table for data that is contained in a datafile.

See Oracle Database Administrator's Guide for more information on external tables. Load data across a network. In the following example, a new table named dependents will be created in the HR sample schema. It will contain information about dependents of employees listed in the employees table of the HR schema. Create the data file, dependents. You can create this file using a variety of methods, such as a spreadsheet application or by simply typing it into a text editor.

It should have the following content:. You create a separate version of the Inbound Flat File Conversion program for each interface table. This diagram shows the process for updating JD Edwards EnterpriseOne interface tables using flat files:.

Figure Flat file conversion program process flow. The conversion program uses the F table to determine which flat file to read based on the transaction type that is being received. This list identifies some of the information that resides in the F table:.

A code that indicates the direction of the transaction. An identifier that marks transaction records as header, detail, and so on. The conversion program recognizes both the flat file it is reading from and the record type within that flat file. Each flat file contains records of differing lengths based on the corresponding interface table record.

The conversion program reads each record in the flat file and maps the record data into each field of the interface table based on the text qualifiers and field delimiters specified in the flat file. All fields must be correctly formatted for the conversion program to correctly interpret each field and move it to the corresponding field in the appropriate inbound interface table.

The conversion program inserts the field data as one complete record in the interface table. If the conversion program encounters an error while converting data, the interface table is not updated. Because the flat file is an external object that is created by third-party software, the conversion program is not able to determine which flat file data field is formatted incorrectly. You must determine what is wrong with the flat file. When the conversion program successfully converts all data from the flat file to the interface tables, the conversion program automatically deletes the flat file after the conversion.

After the data is successfully converted and if you set the processing option to start the next process in the conversion program, the conversion program automatically runs the inbound processor batch process for that interface table.

If you did not set up the processing option to start the inbound processor batch program, you must manually run the Flat File Conversion RC batch process.

If the flat file was not successfully processed, you can review the errors in the Employee Work Center, which you can access from the Workflow Management menu G After you correct the error condition, run RC again. The identifier that marks EDI transaction records as header and detail information. This is an EDI function only. Because of changes to server operating systems and the various ways that operating systems store files, JD Edwards EnterpriseOne supports the business function only when run from a Windows platform.

To ensure that flat file data is properly formatted before it is inserted into interface tables, the business function uses the F table to obtain primary index key information. So that the business function can find the F table, you must take one of these actions:. To map the table in the system data source, add an OCM mapping that points the F table to the central objects data source.

If you generate the F table in the business data source, you must ensure that file extensions on your PC are hidden. To hide file extensions, complete these steps:. You must also ensure that the Flat File Name field in the F table has a file extension. These two errors might occur when you use the business function to convert flat files:. These errors might occur as a result of problems with user setup or with the configurable network computing CNC implementation:.

If you use JD Edwards EnterpriseOne-generated flat files and the recipient system is not expecting Unicode data, you will not be able to read the flat file correctly.

If the flat file is a work file or debugging file and will be written and read by JD Edwards EnterpriseOne only, the existing flat file APIs should be used.

For example, if the business function is doing some sort of caching in a flat file, that flat file data does not need to be converted. The flat file conversion APIs enable you to configure a code page for the flat file at runtime.
