2909169 - External Service Confirmations Not Posted to G/L Account Defined in Purchase Order Item

• You account a Purchase Order Item of type Service to a Project task as well as a specific G/L Account.
• When checking the External Service Confirmations on the assigned Project task you expect these expenses to be posted to the, in the Purchase Order Item assigned G/L account. However, the G/L account derived is different. 

SAP Business ByDesign

1. Access Purchase Order XXX (XXX represents the Purchase Order ID).
2. In the Purchase Order go to the Items tab. 
3. Select item XXX-AA (XXX-AA represents the Purchase Order Item ID). 
4. Navigate to the Account Assignment sub-tab.
5. The Item is assigned to Project Task XYZ-XX and Account Determination group ABC (XYZ-XX represents the Project task, ABC represents the Account Determination Group.

You expect that all expense postings, such as External Service Confirmations or Supplier Invoices will be posted to G/L Account YYYYY (YYYYY represents the G/L account ID) which is assigned to Account Determination group ABC in Fine Tuning.

However, the Service Confirmations are posted to G/L account ZZZZZ (ZZZZZ represents a different G/L Account).

Depending on the business transaction, directly created from the Purchase Order, the respective G/L account is derived:

• For the external service confirmation business transaction, the Fine Tune setting for Account Determination Cost, in the Service tab is prioritized. This setting is linked to the defined Account determination Group as maintained in the Valuation Master Data of the used Service. The resulting Supplier Invoice will also be accounted to this G/L Account. 
• However, if you create a Supplier Invoice directly from the Purchase Order, without a delivery (Service Confirmation), then the Fine Tune setting for Account Determination Cost, in the General Expenses tab is used. This setting is linked to the maintained data in the Account Assignment tab of the Purchase Order item. 

Actual Service Cost Allocations, like External Service Confirmations for a Purchase Order Item are posted according to the Service tab of the Cost Account Determination:

1. In Fine Tuning access the Charts of Accounts, Financial Reporting Structures, Account Determination activity. 
2. Under Account Determination choose Costs.
3. Find the Service tab. 

Expense Postings related to a Service but without Service Confirmation postings, such as Supplier Invoices, are posted as General Expenses:

1. In Fine Tuning access the Charts of Accounts, Financial Reporting Structures, Account Determination activity. 
2. Under Account Determination choose Costs.
3. Find the General Expenses Tab. 
4. Find Account Determination Group ABC. 
5. In the General Expense Column G/L account YYYYY is assigned. 

This is expected System behavior.
