In interactive demand planning, you can display a key figure in a unit other than the unit set for the planning area in Customizing. The data is always saved in the unit set for the planning area in Customizing.
In the product master record(s), you have defined factors for any conversion between units of measure that is not based on the Système International d'Unités (SI = International Unit System). For example, a conversion from pieces to pallets is not defined by the SI; you must therefore define it in the product master record. The SI defines that a millimeter is one thousandth of a meter; therefore, you do not have to define this conversion in the product master record.
The unit of measure in which products are displayed in interactive planning is determined as followed:
If the UOM indicator is set in the key figure details of the planning area, products in the interactive planning table are displayed in their base unit of measure as opposed to the base unit of measure of the planning area provided that the product characteristic is 9AMATNR or you have specified another characteristic for the product in maintenance of the masterplanning object structure. The indicator is set by default. Key figures are still saved in the base unit of measure of the planning area.
In the planning table you can overwrite the base unit of a product with another unit, provided that one of the following conditions is fulfilled:
· The unit is defined in the Système International d'Unités (SI = International Unit System). For example, you can display tonnes in kilograms.
· The conversion factor between the base unit of the product and the unit in which you want to display the product - for example, the base unit of the planning area - is maintained in the product master record.
The unit of measure in which a unitless key figure is displayed in interactive planning is determined by the unit you enter in the Unit of measure field in the key figure details of the planning area . An example of a unitless key figure is a percentage difference between two other key figures, for example, the percentage difference between planned demand and actual sales. If you make no entry, the unit cell of the key figure in interactive planning is empty. No automatic unit conversion is possible for unitless key figures.
If you overwrite a currency unit, the values of that key figure are automatically converted to the new currency.
If you overwrite a unit of measure, the system converts the quantities of that key figure provided that one of the following conditions is fulfilled:
· Conversion is possible via the SI (for example, 1 tonne = 1000 kg).
· You are planning a product at the detailed level, and a factor for the conversion between the unit of the planning area and the base unit of the product has been defined in the product master record.
You are working in Interactive Planning at detail level with several products. These products have their own base unit of measure. The planning area has a particular unit of measure, for instance Piece. The products also have a common additional unit of measure, for example Kg. In the product master two conversion factors have been entered:
· Between the base unit of measure for the product and the unit of measure for the planning area
· Between the base unit of measure and the additional unit.
If the total line has been fixed, you switch from the unit of measure for the planning area to the additional unit (by choosing the Set (aggregate) option from the context menu),and then change an entry at detail level, the 'fixed' total also changes. This appears to contradict the idea behind fixing.
This is intentional and is implicit in the system design.
In liveCache data is always saved in the unit of measure of the planning area. This means that the system always first converts the currently displayed unit to the unit of measure of the planning area. It then makes the changes.Since the total is fixed, the changed quantity is subtracted from the other (unfixed) products at detail level. These products have other
conversion factors. As a result the quantities in the additional unit of both the products that were changed and the total are changed to maintain consistency at the level of the unit of measure of the planning area. The qunatity in the unit of measureof the planning area remains constant.
In the above example
The base unit of measure for both products and the unit of measure of the planning area is <Z1>Piece</> The following conversions factors have been entered in the product masters:
Product A 1 pc = 5 kg
Product B 1 pc = 20 kg
You enter 100 pieces for each product, the total is therefore 200. You fix the total.You change the unit of measure to kg for all entries (choose Unit of Measure -> Set aggregate from context menu). The system displays quantities of 500 kg for product A and 2000 kg for product B. You change the quantity for product B to 2500 kg. Internally (step 4) the system converts the 2500 kg to 125 pieces. Since the total is fixed the quantity of product A is reduced to 75 pieces. These figures are converted back to Kg and displayed.
