SAP ABAP Naming Standards

If you wish to display text in any of your reports that needs to be printed, then you can make use of text elements. It is a good practice not to hard code the text in the programs. If the text is maintained centrally, then it can be called in any report and redundancy can be avoided. Moreover if the text needs to be changed then it can be done at one place rather than changing every instance if it is hard coded.

Text element maintenance can be done in the ABAP Workbench. It is used to maintain program text in different languages. The text that program uses can be maintained centrally for a program.

Program to display sales order header data

If your job is to write ABAP programs/ reports you need to familiarize yourself with various functionalities of SAP. The SAP Sales and Distribution module (SD) allows you to create a Sales order. As an ABAPer you need to know at least the basics of Sales order creation. The transaction for creating a sales order is VA01, to Edit Sales order is VA02 and just to display a sales order is VA03. In case you are unable to create a sales order you can play around with an existing one in the development server. First open the sales order in the display mode and understand the fields that need to be extracted. Make a note of the tables.

In this program we will display the sales order header data.

Following fields will be displayed

• Sales Order number
• Sold to party number
• Ship to party
• Buyer
• Net Value
• Payment Terms
