Creating a Security Order/Contract 
Use
You can create a security transaction as an order or directly as a contract.

Depending on the settings you make in Customizing for Basic Functions in the Define Field Selection node, you can set up the entry fields that are available to you in a variety of ways. You can set up each field to appear as an optional, required, or display field, or you can hide each field.
Procedure
The initial screen for creating a security transaction appears.
The upper part of the screen displays the Company code, the ID number (choose
to display the class master data), the Transaction type and the current Activity category.
The screen contains various tab pages on which you enter the transaction information. Depending on the settings you make in Customizing for basic functions when you choose Define Field Selection, you can display different tab pages for Orders and Contracts. (However, you cannot hide the Structure tab).
