Intermediate Material Storage in Storage ResourcesYou can use storage resources in the master recipe and process order to plan the storage of materials during production and between two manufacturing levels.
You can also use an ordinary storage location for intermediate storage. However, the storage resource has the following advantages:
For a storage resource, you can define both a production capacity that is valid for a limited period of time and a storage capacity in the form of a maximum stock quantity.
Stock and capacity data can be passed on to the Process Flow Scheduler (PFS) or several other planning tools via the POI interface (Production Optimization Interface) The planning tool can thus take the storage capacity and the stocks to be expected into account during capacity requirements planning.
A storage location and a storage resource must have been created in the system for the storage facility you want to use to temporarily store the material. The storage location must have been assigned to the storage resource.
You can use storage resources to reproduce the following scenarios:
Pure intermediate storage
Operations in which the material is processed and temporarily stored in the same resource
Pure Intermediate Storage
In this case, you use a storage resource to which you only assign a storage capacity in the form of a maximum stock quantity. You reproduce the material flow as follows:
Intermediate Storage Between Manufacturing Levels
You can temporarily store the material produced in one manufacturing level until the next manufacturing level. Depending on the type of product, you proceed as follows:
For the leading product (header material)
In the production version of the first manufacturing level, you assign the storage location of the storage resource where you want to store the header material to the header material.
In the second manufacturing level, the same material is contained in the material list as a material component. You assign the same storage location to the material.
For co-products and by-products
Co-products and by-products are listed as material components with a negative quantity in the material list of the first manufacturing level. You assign the storage location of the storage resource where you want to store the co-product or by-product to the material component.
The same material is listed with a positive quantity in the material list of the second manufacturing level. This means that it is to be withdrawn from storage. You assign the same storage location to the material.
Intermediate Storage Within a Manufacturing Level
A material component that is to be temporarily stored within a manufacturing level (for instance, an intra material) is contained in the material list twice:
As a material component with a negative quantity that is placed into storage
As a material component with a positive quantity that is withdrawn from storage
You assign the storage location of the same storage resource to both material components.
Process Step Including Intermediate Storage
For these operations, you use a storage resource to which you have assigned both a storage capacity in the form of a maximum stock quantity and a production capacity that is valid for a limited period of time. You assign the storage resource to the corresponding operation as a primary resource. You reproduce the material flow as follows:
Intermediate Storage Between Manufacturing Levels
You can temporarily store the material produced in one manufacturing level in the resource in which the last process step was carried out. You do this in exactly the same way as in pure intermediate storage.
In the production version of the first manufacturing level, you assign the storage location of the storage resource, that is, the storage location for the primary resource of the last process step, to the header material.
In the second manufacturing level, the same material is contained in the material list as a material component. You assign the same storage location to the material.
Intermediate Storage Within One Manufacturing Level
If you want to store the material component temporarily within a manufacturing level, you proceed as follows:
If the material does not change during the process step:
The material to be stored is contained in the material list twice:
As a material component with a negative quantity that is placed into storage
You assign this item to the last phase before the storage operation.
As a material component with a positive quantity that is withdrawn from storage
You assign this item to the first phase after the storage operation.
If a new material is produced during the process step:
The material list contains the following items for the old material:
A material component with a negative quantity that is placed into storage
You assign this item to the last phase before the storage operation.
A material component with a positive quantity that is withdrawn from storage
You assign this item to the phase for the process step within the storage operation.
The material list contains the following items for the new material:
A material component with a negative quantity that is placed into storage
You assign this item to the phase for the process step within the storage operation.
A material component with a positive quantity that is withdrawn from storage
You assign this item to the first phase after the storage operation.
