Price Calculation for Price Families 

Use

Using price families you can create defined price relationships between different articles that you want to use in sales price calculation. Each price family contains a leading article for price calculation called the master article, and subordinate articles, which are dependent on the master article and whose sales price is determined by the price relationship. Within a price family, subordinate articles with identical price relationships are grouped together in family groups.

Price families ensure the consistency of fixed price relationships. They also help simplify sales maintenance because the sales prices of the subordinate articles are adjusted automatically.

For more information on creating and maintaining price families, see Creating Price Families.

Prerequisites

You have defined price families using the Maintain Price Families transaction (PRFAM) and activated these price families for use in sales price calculation.

Scope of Functions

Creating price families makes it easier to select articles that are linked in a price relationship. If you enter the master article of a price family on the selection screen, pricing items will automatically be generated for the subordinate articles in that price family as well. If you enter a reference article for a family group, all articles in this family group are also selected. If reference articles and other subordinate articles are selected without the master article, warnings will appear in the sales price calculation log, informing you that calculation is going to be performed without reference to the master article.

The pricing items of the subordinate articles belonging to a master article are not displayed in the pricing table unless they were listed explicitly on the selection screen. If you use list group B to display the pricing table, however, you can call an expansion function in the row of the master article. This causes the pricing items of the subordinate articles that were initially hidden to be displayed below the master article. The row for the master article also has a compress function with which you can hide the pricing items for the subordinate articles again.

When creating pricing items for subordinate articles, their final price is determined from the final price calculated for the master article using the price relationship entered in the price family. Price point rounding may also be carried out if you have set this for the family group of the subordinate article. Whether the sales price of a subordinate article can be changed or not depends on the Price Changing indicator maintained for the family group.

·        If this indicator has the value 1 (Price Change Permitted at Family Group Level Only), the sales price can only be changed for the reference article of the family group.

·        If the sales price cannot be changed, the sales side fields of the pricing table are not ready for input.

If you change the sales price of the master article in the pricing table interactively, all the sales prices of the subordinate articles are automatically adjusted in accordance with the price relationship, possibly while also performing price point rounding. If you change the sales price of a reference article, the sales prices of the subordinate articles belonging to the family group concerned are adjusted.

If you change the sales price of the master article or the reference article, any sales price changes made to the dependent subordinate articles at the same time are ignored.

To give you a better overview, you can look at the price calculation for price families on a new details screen. On this screen the various family groups for a selected price family are clearly laid out together with the articles belonging to the groups and the defined and current price relationships. You can also make changes to sales prices on this details screen. You can also jump from this screen to master data maintenance for the price family.

When you save the price calculation for a price family, a distinction is made depending on whether the pricing items for the subordinate articles are expanded. If this is not the case, the hidden pricing items for the subordinate articles are saved automatically when you save the master article. If the pricing items for the subordinate articles are expanded, only those items for which no deviations from the price of the master article are allowed are saved automatically. If a price change is permitted at family group level, the item of the reference article must be selected in order to be saved. All subordinate articles in the family group are then saved automatically in the same way. If, however, items for subordinate articles in such a family group are selected, but the reference article is not, they will not be saved. If price changes at article level are permitted, the item needs to be selected explicitly.
