PositionGeneral
The calculation lines are numbered automatically. If Isah is linked to engineering software, the position number is used to indicate the position (balloon) on the drawing.
This field is only relevant if the order code of the line is 'Purchase to custom order' or 'Purchase to order, commercial quantity'. The supplier in this field is copied to the purchase requirement in the Purchase module. The field value can still be modified here.
Specify how you will obtain the part. You can choose from the following options:
|
This order code indicates that the part will not be ordered until it is required for an order, at which time it will be ordered in accordance with the exact specifications (quantity, length, etcetera) listed in the order calculation. The most basic unit (the stock unit) will be used for the calculation; other settings have no impact on this.
|
|
This setting indicates that the part will not be ordered until it is required for an order. The part will be ordered in the purchase unit set for this part on the Purchasing tab of the Parts form in the Parts module. The number of purchase units required to meet the requirements will be ordered.
|
|
Use this order code to indicate that the part is in stock, and that you will take it out of stock if you need it. If the stock level of the part falls below the minimum, the part will automatically appear on the purchase requirement, and it can be ordered to replenish the stock. If the part is a purchase part, it is ordered in the order quantity set on the Purchasing tab in the Parts module. This tab also shows the minimum stock and the current stock. The unit used for purchase parts is the purchase unit. The requirement is converted into the order quantity as a minimum, and if required, the order quantity is increased by the quantity set in the Increase by field on the Purchase tab. If the part is a production part, the quantity specified in the Batch size field on the Calculation/production tab in the Parts module will be ordered. The unit used for production parts is the stock unit. The requirement is converted into the batch size as a minimum, and if required, the batch size is increased by the quantity set in the Increase by field on the Calculation/production tab.
|
|
Use this setting to indicate that the part is supplied by the customer (who has ordered the finished product in which it will be included). No purchase requirements are created for parts with this order code.
|
|
Use this order code for semi-finished products that will not be assembled until you need them. These parts are parts of the 'Production part' type. To create a separate production order for the semi-finished product, choose order code 'Produce in new production file'. This will create a link between the two production orders, allowing you to see for which production order the semi-finished product is to be produced. No purchase requirements are created for parts with this order code A production file is created to meet the requirement. This can be done when the sales order line is saved or when a calculation is copied. Use the Auto-create production file for sales offer/order? field on the Calculation/production tab of the Parts form to configure the software to automatically create the production file when a requirement arises.

|
Use this order code for semi-finished products that will not be assembled until you need them. These parts are parts of the 'Production part' type. Use the order code 'Copy calculation (phantom)' to merge any underlying calculations into one calculation. The calculation will then include a phantom line that shows the semi-finished product for which the underlying calculation components are intended. All part lines, operation lines, equipment lines, and external operation lines referring to the semi-finished product will contain a reference to the phantom line. Use the Show phantom option to specify whether the phantom line should be displayed on the form. No purchase requirements are created for parts with this order code
|
If the part line contains a semi-finished product, you can copy the calculation of that semi-finished product if it has the order code 'Copy calculation (phantom)'. Once this calculation has been copied, the Copied check box of the semi-finished product will be selected. You can manually change the value of the field.
If a calculation was copied (in case of a part with order code 'Copy calculation (phantom)'), you can choose to display both the semi-finished product and the components of the semi-finished product in the calculation. You can also choose to show only the components of the semi-finished product, and therefore only the calculation lines. If you select the Show phantom check box, the calculation will show the semi-finished product, the phantom, and the underlying calculation lines. If you leave this check box empty, you will see the calculation lines, but not the parent semi-finished product (the phantom).
The Show phantom option is available only for parts with order code 'Copy calculation (phantom)'.
If the External check box is selected, the part calculation line was created by an external application, such as a CAD or PDM integration application. The line is managed mainly in the external application. You can change the line in Isah, but it is possible that during synchronization, it will be overwritten by data from the external application.
If the part calculation line was created in Isah, the check box is empty and the part is managed only in Isah. This is an informational field and cannot be changed.
Dimensions
This is the number of pieces of the part you need in order to make the finished product.
Note: When building the calculation, you should take into account the calculation quantity, i.e. the number of parts to be produced to which the calculation applies. You can find the calculation quantity in the part data on the Calculation/production tab. For example, if the calculation quantity is '10 pieces', fill in the quantity required in order to produce 10 parts.
Specify the length, width, and/or height per piece. Whether or not you can fill in one or more of these fields depends on the setting of the Unit code field on the General tab of the Parts form:
Unit code |
Can a length be filled in? |
Can a width be filled in? |
Can a height be filled in? |
Quantity |
No |
No |
No |
Quantity * Length |
Yes |
No |
No |
Quantity * Length * Width |
Yes |
Yes |
No |
Quantity * Length * Width * Height |
Yes |
Yes |
Yes |
The number in this field is calculated automatically by multiplying the quantity, the length, the width, and the height. The value of this informational field cannot be modified directly.
If the Show costs including waste is selected, the Quantity field will include the waste percentage (available on the Calculation/production tab of the Parts form).
Example
Waste percentage: |
10% |
Show costs including waste: |
|
Quantity: |
5 |
Length: |
10 |
Width: |
10 |
Height: |
10 |
Quantity: |
5,500.00 m3 |
CAD
CAD reference, CAD classification
These informational fields can be used when linking Isah with CAD/PDM software.
This check box is used for the AutoCAD integration. If selected, any text on the memo page of the calculation line is printed on the drawing.
Net dimensions
Quantity, Length, Width, Height
These fields are informational fields that could be used, for example, by the planner. The planner could use them to register the exact quantities and sizes as specified on the drawing.
Waste
The waste percentage is relevant to the calculation of the total quantity required and the total costs of the part line.
If the Show costs including waste check box (part calculation, General tab) is selected, the waste percentage is included in the calculation of the Quantity, Weight, Surface, Variable costs and Total costs fields (see the info bar at the bottom of the screen). If the check box is not selected, the fields will be filled with a value excluding waste.
Example Waste percentage
You need 10 kg of a part as raw material. Experience has shown that you need an additional 20% to eventually be left with a net weight of 10 kg. Your gross requirement will be:
10 kg + 20% of 10 kg = 12 kg
Based on the gross requirement, the waste percentage can be calculated as follows: You are processing 12 kg of a part that results in 20% of waste. Your net quantity will be:
12 kg - 20% of 12 kg = 9.6 kg
The reason why Isah uses the net requirement, is that this is the most practical working method. You will regard the waste percentage as an additional requirement. If you are used to thinking in terms of gross requirements, the waste percentage to be entered in Isah can be calculated. The waste percentage will then be multiplied by 100/(100 - Waste percentage).
If, for example, the waste percentage is calculated as 20% of the gross requirement, fill in the following waste percentage in Isah:
20 * (100/(100-20)) = 20 * 1.25 = 25%.
These fields are informational fields and cannot be modified. They can be filled in automatically only if a weight and surface have been specified for the part on the General tab in the Parts module.
