This simple application, Stock Level Adjustment, allows you to create product records. These could be used in Sales Order Entry and other applications.

When you have finished this first task, you will be able to -

create (or change or delete) records for your products.

This application is deliberately very simplistic. It will allow you to create product records and enter current stock levels.

An experienced operator working on a locally attached terminal would be able to create, authorise and test this application in under 4 minutes.

Product records are indexed by both name and number and can be accessed by either identifier with the same very rapid response times. They may be displayed in name or product number sequence. Products may be sold as units or in packs or by weight, etc.. For each product that is sold in packs, you may indicate the quantity in each pack, whether packs may be split, whether stock is to be allocated automatically when orders are entered, whether the product is sold at a price including or excluding Value Added (or other) Tax, whether the product is a current item or one that will no longer be offered for sale once current inventory has been sold, etc..

This application can easily be extended to handle multiple locations, and, for groups of companies, for each subsidiary and for each location within each subsidiary. In this case, any changes to the stock of a product at any individual location or subsidiary company or location or branch of a subsidiary is automatically reflected in total stock of the product. The application is intended to be used for initial loading of inventory details only. For the purposes of this demonstration, these are entered typed in, but, in a real situation, a program would be written to load the data from an existing file into the ERROS database. No new files or programs will be created when this application is created unless for loading from an existing product data file.

When creating ERROS applications, you can use your own entity type and attribute definitions or any already defined in ERROS or a mixture of the two. All that is required for this application is already defined in the ERROS Open Universal Business Model and you do not need to create any new definitions, so you will not need to use the ERROS Business Modeller.

The example shows how the application is created using the ERROS Application Creator. The example shows how to define the entity types to be used within the application, and how to create menus for those entity types. It also shows how to create an initial menu for the application. Fast path menus that allow operators to access any record with one command are automatically created, and the example also shows how operators can create synonyms for fast path menu entries to allow multiple fast paths to entity types.

If you do not know how to operate ERROS or how to get a sign on screen, click on Operating ERROS. This will start a new browser window so that you can easily switch between operating ERROS and reading the instructions in this window.

If you do not know how to start up ERROS after you have signed on, you will find a link on the previous page.
