# Schema Templates
## Row Layout
The row layout contains the actual calculation.
Here you can create completely individual schemas for your needs.\
The following table provides an overview of the different totaling types.
" "
The “empty” totaling type allows to work without row no.. This allows, for example, to assign “headings” for the upcoming lines.
Formula
With a formula you can e.g. summarize, multiply etc. individual lines. The following operators are available:\
Addition ( + ), subtraction ( – ), multiplication ( \* ), division ( / ), power ( ^ ).
Value
With a value you can give a fixed value to a line. e.g. 500
Item
Summarizes all items of the calculation, taking into account the stored filters.
Work Center
Summarizes all wok centers of the calculation, taking into account the stored filters.
Machine Center
Summarizes all machine centers of the calculation, taking into account the stored filters.
Individual Surcharge
You can assign individual surcharges for items, wok centers and machine centers. To do this, you must enter the row no. of the corresponding line for which you want to assign an individual surcharge in the “Formula field”. Individual surcharges are stored in a separate table.
Sales
Summarizes all calculated sales. See [sales](https://brenkel-solutions-eg.gitbook.io/demandplus+/english/post-calculation#sales)
### Show
This can be used to decide whether the field is displayed or hidden dynamically or statically in the schema.
### Bold
Specifies whether the line will be marked bold later in the schema.
### By Piece
The field "By piece" ensures that the calculated value of the line is again divided by the produced quantity. If the line is used in another formula, the calculation will also continue with the associated unit value. An exception is the type "Sale". Here it is divided by the sold quantity in the scheme.
### Filter
For items, work centers and machine centers you can store as many filters for the line as you like.
A filter can be stored for each field. The filtering is taken into account when evaluating the schemas. You can only pass filters where data records exist in the system. This prevents you from entering the wrong filters and causing problems when evaluating the calculation.
## Column Layout
In the column layout you can define your own columns.
The following table describes the associated fields:
Column No.
Unique no. for the column.
Description
Here you can enter a description for this column.
Column Type
Deviation: If you store a deviation in the column type, deviation columns will be created for the associated columns that are stored in the formula.\
Formula: You can create individual columns that do not have the calculation as a basis, but other columns.
Amount Type
The amount type specifies the prices/costs you want your schema to be filled with.
Formula
The formula field is used to link individual columns. A formula must not refer to deviation columns.
## Process Columns
The Process Columns are only needed when using post calculation processes.
Column No.
Specifies the column no. of the process
Description
Specifies the description of the column. This description will be displayed later in the process for the associated column. By default, it is composed of the description of the row and the column from the template.
Formula
Specifies a formula for calculating the group line for this column.
Template Column No.
Specifies the column no. of the template
Template Row No.
Specifies the row no. of the template
Totaling Type
Specifies how the columns should be calculated in case of a group line.
## Individual surcharge
The individual surcharge is a possibility to individually value single (or several) items, machine centers or work centers.\
Via the search you can find the precalculation surcharges
In principle, 3 “areas” must be distinguished. The following table lists the hierarchy for the surcharges.
{% hint style="info" %}
Hierarchy (Descending) – corresponds to the “Type” field
{% endhint %}
Item
Item, Item Category, All Items
Machine Center
Machine Center, All Machine Center, Work Center, All Work Centers, Work Center Group
Work Center
Work Center, All Work Centers, Work Center Group
