Assemblies are entered using the assembly tool:



Partnumbers for the assembly itself and all its component items should be entered into Herschel using the Store module's partnumber tool option before entering the assembly.

 

An assembly consists of two parts - details and an unlimited up to 9999 lines. The details are entered first and hold the following important data:


Current Issue

The current issue of the assembly.

Phantom Assembly

Whether the assembly is a phantom assembly. A phantom assembly is an assembly that is made as part of the manufacturing process, but which is not normally held in stock. When a kit list for a works order is created using the Make module's works order tool, if Herschel finds a phantom assembly then it will not include the phantom itself in the kit list. Instead, it will include all the component items of the phantom assembly in the kit list.  When used correctly phantom items can simplify the entry of assemblies and help ensure that an assembly reflects the manufacturing processes used in its manufacture. 

Labour Cost

This is the labour cost of assembling or processing the component items to produce the assembly.

Overhead Cost.

This is the overhead cost of assembling or processing the component items to produce the assembly.

Comment.

A comment.

Usual Route Number

The usual route number to use for costing purposes (if you're using the Shop module).

Typical Batch Size 

The typical batch size to use for costing purposes (used for calculating scrap allowances).

Assembly Status 

The assembly status of the assembly.  If it is not OK to make then no works orders can be raised for the item in the Make module.

Last Update

Details of when the assembly was last updated.


The lines page lists the component items that go into the assembly:



Each line is separately numbered. It is sensible to use line numbers with increments of five (i.e. 5, 10, 15, 20....) when entering assembly lines on the add new line page - this leaves space for extra lines to be inserted at a later date if necessary. As well as the quantity of the item needed, a reference of up to 100 characters can be entered for each line, and a comment:



The delete page can delete a single line, all lines or all lines and details:



If your line numbering does get confused the renumber page can renumber the lines for you at any time.  Lines can be renumbered by line number, partnumber, family, reference or location:



Occasionally it may be convenient to use a different unit of measure in an assembly from the unit of measure used for stock control.  For example a chemical may be stored in kilograms but used in very small amounts in assemblies.  Using the stock unit of measure means that the amounts in the assemblies are very small numbers with a lot of potentially confusing decimal places.  

 

The assembly unit of measure tool allows you to enter an assembly unit of measure and a factor that tells the system how the assembly unit of measure relates to the usual stock unit of measure.  For example a chemical could be stored in kilograms with the assembly UOM defined as GRAM with a factor of 1000.  Assembly amounts can be now entered in grammes and confusion avoided:
