Devaluation allows for changing values of resources in a warehouse. Depending on resource collection method determined in the system configuration, it is possible to:

• change price or value of specified deliveries for FIFO/LIFO databases
• change price/value of specified lots registered in a warehouse for AVCO databases

A list of documents is available in menu Warehouse (Resources) → Devaluations.

Possibility of creating devaluations is available for a user who belongs to operator groups with permission Access to purchase prices  granted.

In case in a warehouse there is a devaluation document with Initiated or Unconfirmed status, in a document including devaluated deliveries (FIFO/LIFO)/lots (AVCO), it is not possible to:

• add an item lot to a document (database with AVCO method of queuing resources)
• deleting an item from the list of items in an unconfirmed document
• change quantity of an item/subitem in an unconfirmed document
• issue a quantity/value correction (value correction for documents for released items)
• confirm a document and its corrections
• change warehouse to a warehouse subject to devaluation
• add/remove a subitem
• introduce modifications in the tab Deliveries in item details
• add/remove a subitem
• delete an unconfirmed document
• cancel a document

In order to add a new devaluation document, it is necessary to select [Add] button. It results with opening a new devaluation document form

Detailed description of the document form and its tabs can be found in subcategory Document forms.

Unique fields of devaluation document header:

• Value Before Devaluation
• Value After Devaluation
• Devaluation Value – value of devaluation document, calculated as a difference between value before devaluation and value after devaluation
• Devaluation Date – date on which value of a warehouse resource was changed. The devalued resource retrieved onto document for released items has always value the same as after devaluation, irrespective of date of sale set on that document. Devaluation date is taken into account in archival stock levels, item history and delivery history.

Unique fields of devaluation Items tab:

• Delivery Date – date with which a given item was received into original warehouse (available only for databases with FIFO/LIFO method selected)
• Document – number of a document which registered receipt of an item into warehouse (available only for databases with FIFO/LIFO method selected)
• Source Document – number of a document which created a delivery (available only for databases with FIFO/LIFO method selected)
• Price Before Devaluation – unit purchase price of an item before devaluation
• Price After Devaluation – unit purchase price of an item after devaluation
• Value Before Devaluation – purchase value of an item before devaluation
• Value After Devaluation – purchase value of an item after devaluation
• Devaluation Value – value of an item, calculated as a difference between value before and after devaluation

When adding an item onto devaluation document, whole quantity of a resource stored in a given warehouse is retrieved (also those quantities which have resource reservations registered) with a possibility of deleting a selevted delivery. Moreover, depending on the set resources collection method:

• FIFO/LIFO – all deliveries associated with a given item, which are stored in warehouse selected in a document header, are added. Document item is in this case delivery of the given item.
• AVCO – all lots of a given item, which are stored in warehouse selected in a document header, are added. Document item is in this case lot of the given item.

Upon selecting at least one item a user is able to recalculate entire Devaluation document. Selecting [Recalculate] button results in opening the following form.

It is possible to determine fields which are to be subject to modification:

• Field
  • Value
  • Price
• Change Direction
  • Reduction
  • Increase
  • Fixed Value
• Change
  • Percentage
  • Value
• Value by which change will be made

Confirming a devaluation document results in updating:

• value of a resource in the warehouse according to value specified in field Value After Devaluation
• price of a resource in the warehouse according to formula Value after devaluation/Quantity of resource in the warehouse
• purchase value of a given lot, which will be calculated as total of values after devaluation of resources and other resources
• unit price, which will be calculated according to formula Lot value after devaluation/Quantity of the given lot resources
• resource which has been reserved with a warehouse document for released

When confirming a devaluation document, Devaluation Date is verified.In case of resource queuing method:

• FIFO/LIFO – if delivery date is later than devaluation date, it is not possible to confirm the document
• AVCO – parameter Control chronology of resource modifications is verified.If date of the last modification of resources uploaded onto the DV document is later than devaluation date, it is not possible to confirm the document

During the cancellation the system verifies if in a warehouse there is any quantity of a resource from delivery as that which was subject to devaluation. In case the quantity:

• is available – the value of a resource in a warehouse is update by the amount which was devaluated for that resource

• is not available – a CC is generated. A CC generated this way is not associated with any warehouse document.

During the cancellation the system verifies if in a warehouse there is any quantity of a resource from delivery as that which was subject to devaluation. In case the quantity:

• is available – the value of a resource in a warehouse is update by the whole value of a given item of the devaluation document

• is not available – a CC is generated for a given warehouse for the whole value of a given item of the devaluation document
