As of Release 4.6A, the securities order function is integrated into the Treasury transaction management function as part of the standardization process across the whole of Treasury. This means that the processing functions for financial transactions in the money market, foreign exchange, derivatives and securities areas are practically the same.

The structure of the general transaction management function is different from the previous order management function. As a result, the securities area has undergone several changes:

A) The IMG for the securities area includes the following new IMG activities:

• You find the following settings by choosing Securities ® Transaction and Position Management ® Functions ® Transaction Management:
• Number ranges
• Define Number Ranges for Transaction
• Define Number Ranges for Underlying Transaction
• Define Transaction Types
  
  Specify the transaction types required for purchases and sales per product type.
• Flow Types (Transaction)
  
  Transaction management in Treasury requires other flow types than the securities flow types.
• Define Flow Types for Transaction
• Assign Flow Types to Transaction Type
• Define Derivation Procedures and Rules
• Assign Transaction Flow Types to Securities Flow Types
  
  Since the position management function in the securities area is based on the 'old' securities flow types, you must uniquely assign the 'new' transaction flow types and the 'old' securities flow types for transaction processing here.
• Correspondence
• Define Correspondence Types
• Define Correspondence Activities
• Define Printer Options
• Define Fax Options (Spool)
• Check

• Define Reservation Reasons ('old' IMG activity, stays the same)

• To go to the IMG activity Define Account Determination for Transaction Flow Types, choose Securities ® Transaction and Position Management ® Functions ® Accounting ® General Ledger Update.

B) The following IMG activities are no longer included in the securities area:

• Define Order Number Range
• Maintain Active Indicator (Release)
• Define Release Status Parameters (Release)
• Define Status per Product Type
• Define Status Transfers per Product Type

Customers, who already use the securities module, must convert their existing transactions in the system to the new transaction management functions as a result of the move.

To convert existing transactions, SAP provides this conversion program (call it up using transaction TS_CONVERT). It is described in more detail below. Conversion does not take place automatically, but instead in several steps. Some of these steps require you to make certain settings in Customizing.

 The conversion program for securities transactions not only supports the migration of the 'old' securities transactions to the new transaction management functions, but also the delta Customizing settings that must be made for the new transaction management functions before the data can be migrated.

Since the program only converts the transactions that have Order or Posted settlement status, you must have settled or deleted all the transactions that still have Execution or Planned settlement status before you upgrade to 4.6A.

The conversion program consists of five report programs, which you run in sequence. You are required to make some Customizing settings before you start the conversion. We recommend that you run the individual report programs in the following order, since some report programs are a prerequisite for other report programs:

1. Generate Transaction Types

This report program generates the relevant transaction types per product type for the existing transaction flow types for purchase and sale transactions. The IMG activity Define Transaction Types is generated automatically from the existing information for the product types and for the flow types. The report program also assigns the transaction flow types to the transaction types (IMG activity Assign Flow Types to Transaction Type).

2. Generate Flow Data

This report program copies the existing transactions that have Order and Posted settlement status to the new transaction management functions. It does not convert transactions that have been reversed and deleted. A new transaction is created with a new number for each ’old' transaction and the number assignment is saved. This means that you can branch from the new transaction to the old one.

3. Generate Assignment of Planning Levels

This report program updates the assignment of the planning levels.

4. Generate Account Determination

This report program generates the account determination for the transaction flow types in the same way as it generates the account determination for the securities flow types.

5. Generate Assignment of Position Management Procedure
   
   As part of the new transaction management functions, the function for determining price gains/losses has also been redesigned. As a result, there is a new IMG activity, Assign Position Management Procedure, which uses this report program to generate the previous position management settings.

We recommend that you perform a test run for all report programs first. Only start the update run when you are sure there are no errors in the test run.

When you have eliminated all the errors from the report programs, you have transferred all the transactions available to the new transaction management functions. You have also made all the Customizing settings and can now enter new transactions using the new transaction management functions.
