Procedure documentation Generating an SAP Data Structure for the Conversion Program Locate the document in its SAP Library structure

You can use the ABAP Dictionary to generate data structures for ABAP Dictionary objects (tables, views and structures) in any of the following programming languages:

You can then incorporate these data structures in your conversion program.

For most of the SAP data transfer standard programs, SAP has also provided special data structure identifiers. With such an identifier, you can generate a listing of all of the table fields that are required by the data transfer program. You manage these programs in the Data Transfer Workbench. If you have generated your own program to transfer data from an external file, the SAP data structure definition that you require is stored in the data declaration section of the program.

Conversion Programs in ABAP

If your conversion program is written in ABAP, you can use the information from the ABAP Dictionary directly to record the data structure of your tables.

The graphic below shows the structures of conversion programs in ABAP and as external programs written in other languages.

This graphic is explained in the accompanying text

Including Table Structures in Conversion Programs: ABAP and Other Languages

Procedure

To generate a data structure, proceed as follows:

  1. Choose Tools ® ABAP Workbench and then ABAP Dictionary.
  2. In the ABAP Dictionary, select Environment ® Generate table description.

    3. With this function, you can generate the structures of ABAP Dictionary objects in programming code. You can then add this code to your conversion program.

  3. Specify the programming language in which the structure should be generated and identify the tables to be included.

    4. If you wish to use a special structure identifier for a standard SAP batch input standard program, then enter the identifier in the Key in TSRCG field. Example: The identifier AM-ANLA generates the data structure required for data transfers for the asset management application.

  4. The system displays the data structure in list form, as in this example in PL/1 from the asset management application (AM-ANLA):
