This topic provides information about the elements in this window in Visma Net, such as fields, field values, buttons, and check boxes. For a more accurate estimation of the project profitability, you can capture such expenses as the project overhead by **allocating** the project. To calculate the overhead for projects, you create an allocation rule. Using this allocation rule, the system creates allocation transactions based on the project transactions posted to a particular account group or specific groups. These allocation transactions post the calculated overhead amount to the specified account group. ## Search line in list window If you are in the list window, the first line in the table is a search line. Each column has a search field which you can click to search for or filter on specific values and narrow down the displayed table rows. You can search and filter in as many columns as you need to, to only display the results you want to view. There are two types of search fields: + White: here you can type a specific search term to display results in this column containing this exact value. If you search on several (partial) words, you can separate them by a space or **%** and get different results: + space: the result contains the words in any order, + **%**: the result contains the words in the specific order, and the **%** functions as a wildcard as well. + Grey: you can click this to open the column filter pop-up window where you can filter the results for this column. ## The top part By using the elements in this area, you can specify the settings for a new rule or select an existing rule to view or modify its details.
Element Description
Allocation rule The unique identifier of the rule.
Description The description of the allocation rule.
## The left pane In the left pane, you define the sequence of steps for the selected allocation rule. You then define the actual calculation rules and allocation settings for each step by using the tabs in the right pane.
Element Description
Step ID The identifier of the step in the allocation rule.
Description The description of the step.
## The Calculation rules tab For a step selected in the left pane, you can specify which transactions to use as the base for allocation and how to generate the resulting transactions.
Column Description
Allocation method

The method to be used for allocation. Select one of the following options:

Allocate transactions
The system calculates the amount to allocate by using the underlying transactions and their amounts. You use this option to implement a time and materials or cost-plus-project scenario in which the project total is calculated as a percentage of its costs.
Allocate budget
The system calculates the amount to allocate as a percentage of the task budget (other amounts are ignored and not used in calculations). You use this option to implement a fixed-price project scenario in which the project total is predefined by a budget.
Create allocation transaction

If you select this check box, the system will create the allocation transactions resulting from this step.

If you do not select this check box, the resulting transactions will be placed on a clipboard until used by another allocation step.
### The Selection criteria section
Element Description
Select transactions

The way the system should select the transactions to be used as the basis for generating allocation transactions in this step. Select one of the following options:

Not allocated transactions
The step will be applied to original project-related transactions that were not allocated. If you select this option, the fields Account group from and Account group to become available.
From previous allocation steps
The step will be applied to the transactions generated for previous steps and placed on the clipboard. If you select this option, the fields Range start and Range end become available.
Account group From

The account group that starts the range of account groups whose transactions are involved in this allocation step. (The account groups are ordered alphabetically.)

This field is only available if the From previous allocation steps option in the Transaction options section is selected.
Range start

The starting step that opens the range of previous steps,so that their allocation transactions can be used by the current step.

This field is only available if, under the Select transactions, you have selected the option From previous allocation steps.
Account group To

The account group that ends the range of account groups involved in this allocation step. (The groups are ordered alphabetically.)

This field is only available if, under the Select transactions, you have selected the option From previous allocation steps.
Range end

The step to end the range of previous steps whose allocation transactions will be used by the current step.

This field is only available if, under the Select transactions, you have selected the option From previous allocation steps.
### Rate settings section
Element Description
Rate type The rate type to be used for this step of the allocation rule.
If @Rate is not defined

The default action you want the system to perform if the value for the @Rate has not been defined after execution of the step.

Select one of the following options:

Set @Rate to 1
To set the @Rate to 1.
Set @Rate to 0
To set the @Rate to 0.
Raise error
To show the error message and stop processing.
Do not allocate
To skip the generation of the allocation transactions.
### The Calculation settings section
Element Description
Quantity formula

The formula you want to use to calculate the quantity for allocation transactions. Click icon-select to open the window.

You can also use other transaction parameters to calculate the quantity. The resulting value is normally used to track task or project completion or the total quantity for the task or project.
Formula invoiceable qty.

The formula for calculating the invoiceable quantity for allocation transactions. Click icon-select to open the window.

You can also use any other transaction parameters to calculate the invoiceable quantity. Generally, you use this field to define the quantity for which you will charge the customer during invoicing.
Amount formula

The formula for calculating the amount of allocation transactions. Click icon-select to open the window.

You can also use any other transaction parameters to calculate the amount. The resulting value is normally used to track task or project completion or the amount for the task or project.
Description formula

The formula you can use to generate the descriptions for allocation transactions. Click icon-select to open the window.

If you use this step of the allocation rule to accumulate invoiceable amounts, the text the formula generates will be displayed on the invoice.
## The Allocation settings tab On this tab, for the step selected in the left pane, you can specify how to allocate the project amounts to specific accounts and account groups. ### The Transaction options section
Element Description
Post transaction to General ledger

If you select this check box,the allocation transactions will be posted to the general ledger.

If you do not select this check box, the transactions are not posted to the general ledger. Instead, they are only used to track analytical or statistical information for projects, and you can only specify account groups (not accounts) in the Debit transaction and Credit transaction sections.
Reverse allocation

Indicates when the allocation transactions should be reversed. Select one of the following options:

On invoice release
The allocation transaction is reversed immediately after the release of the invoice generated on the basis of this allocation transaction.
On project invoicing
The allocation transaction is reversed immediately after the invoice is generated on the basis of this allocation transaction.
Never
The allocation transaction is never reversed.
Date source

Indicates how the date for the allocation transactions is defined. The following options are available:

Original transaction
Take the date from the original transaction.
Allocation date
Use the date of the allocation.
Create transaction with zero qty.

If you select this check box,the system will create the allocation transaction, even if it has a quantity of zero. As a result, such transactions will be available in the invoice after you run invoicing.

If you do not select this check box, the system will not create transactions with zero quantities.
Create transaction with zero amount

If you select this check box,the system will create the allocation transaction, even if it has an amount of zero. As a result, such transactions will be available in the invoice after you run invoicing.

If you do not select this check box, the system will not create transactions with zero amounts.
Create non-invoiceable transaction

If you select this check box,the system will create the allocation transaction, even if it is not invoiceable. As a result, such transactions will be available in the invoice after you run invoicing.

If you do not select this check box, the system will not create transactions that are not invoiceable.
