| ASCII File Fields (daxch0103s000) |  |
| Use this session to create ASCII file fields in an ASCII file that is used in the exchange scheme. Tip You can use three methods to create an ASCII file field: Copy an existing data definition file of an ASCII file generated during the data export. Copy the definition from the ERP LN table definitions if there is no ASCII data definition file available. Define the ASCII file fields manually. To create ASCII file fields, do as follows: Enter the field number, and the field name and select the field type. Specify the field length and start position of the ASCII file field under Field Dimensions. Specify additional details of the ASCII file field under Numeric Format. Note Do not create more than 250 fields per ASCII file. If you want to add more information, click the Text button on the toolbar to start the text editor.

Fields | Description
Exchange Scheme | A blueprint that defines the general parameters that are used during a data-exchange process, such as the location of files, the use of an audit trail, and other default settings. The exchange scheme contains all definitions of the data that must be exported and/or imported. The ASCII files, conditions, batches, table and field relations, ranges, and conversions that belong together are grouped in an exchange scheme. The exchange scheme is created in the Exchange Schemes (daxch0501m000) session.
ASCII File | The ASCII file name. Every ASCII file that is linked to one or more ERP LN tables must have a unique ASCII file name. If you want to copy the of the ERP LN table fields automatically, the ASCII file name must be the same as the ERP LN table name. This is an option if you do not have a data definition file of the ASCII file. The ASCII file is created in the ASCII Files (daxch0102m000) session.
Field Number | Enter a field number for the ASCII file field. If a field separator is used, ASCII file fields are positioned according to this number. The field separator is defined in the Exchange Schemes (daxch0101s000) session. Note The number is increased automatically: when you define a new ASCII file field, ERP LN enters a number of value ten greater than the field with the highest value. The order of fields specified by the field number is important, not the actual field number. Because numbers like 10, 20, 30, and so on are used, it is easy to insert field numbers at a later stage.
ASCII Field | Enter the name of the ASCII file field. This field is automatically filled in if a data definition file of the ASCII file or ERP LN table is used. The ASCII field is associated with the data found in the physical ASCII file in a certain column. These fields are mapped to ERP LN table fields in the import and export file relation sessions.
Description | Enter the description of the ASCII field.
Field Type | Enter the data type of the ASCII field. Allowed values See Possible values
Start Position | Enter the column number in an ASCII file where the ASCII file field starts. The start position declares the position of the data in physical ASCII file. If no field separator is defined in the details session of the Exchange Schemes (daxch0501m000) session, the start position must be specified. Note If this field is changed, you do not have to generate the import program or the export program again.
Length | The length of an ASCII file field, which is alphanumeric or numeric, with a variable length must be specified. No length is specified for an ASCII file field with a fixed length. Note If this field is changed, you do not have to generate the import program or the export program again. The length of an ASCII file field that represents a multiline text is zero.
Date Format | Define a Date Format for a numeric field in an ASCII file. If no date format is defined for an ASCII file field, the Default Date Format will be used. If the ASCII file field was created using ERP LN audit files, the Default Date Format must be set to ERP LN Number. Note If this field is changed, you do not have to generate the import program or the export program again.
Floating Decimal | If this check box is selected, the decimal point can be placed at any position in the ASCII file field without the decimal actually being present. The number of digits after the decimal point must be specified in the following field.
Nr. of Digits after Decimal | The number of digits after a floating decimal point defines where the decimal point is placed in a numeric field. If the Floating Decimal check box is not selected, this field appears dimmed. Note If this field is changed, you must generate the import program or the export program again.
Text | If this check box is selected, additional information is available for this ASCII file field. The information is generated in the text editor. Click the Edit Text button on the toolbar to start the text editor.
