Purchasing Value Keys

In the material master record, you can store rules governing the admissibility of over- and under-deliveries through Purchasing Value Keys.

Various keys can be defined for different values:

Delivery tolerance limits
Percentage (based on the order quantity) up to which an under-delivery/over-delivery of this item will be accepted or if unlimited over-delivery is acceptable. 5 percentage has been defined for the key 2 here:

Defining Material Groups

In this IMG activity, you define material groups to group together materials with the same attributes or purpose.
You can use material groups to:
•    Limit the scope of analyses
•    Systematically search for material master records via matchcodes


At the IMG menu as shown define the material groups.

Maintain entries as below:

Field Selection

In this section, you Define whether a field is hidden or displayed, or whether an entry is mandatory or optional in material master maintenance by assigning the field to a field selection group.

Field selection group:

Group of several fields to which the same field option applies. The field options are as follows:
•    Hide
•    Display
•    Required entry
•    Optional entry

Each field selection group has a number between 1 and 240. User defined groups are numbered from 210 onwards.

Assign Fields to Field Selection Groups:

To define whether a field is hidden or displayed, or whether an entry is mandatory or optional in material master maintenance, you must assign the field to a field selection group. You may assign a field to one field selection group only.

For example the field Purchasing Group is to be mandatory. The field is MARC-EKGRP. The field selection group is 214. This group controls the field EKGRP and the case when it is to be made mandatory/ optional for entry etc.

 The field reference ROH is the field reference as maintained in the attributes of Material Type ROH. By selecting the option “Reqd Entry” for these Field References, the fields are made mandatory for all materials of type which have the reference as ROH.

Define Number Ranges for Each Material Type

In this step, you define the type of number assignment and the number range intervals for material master records. When creating a material master record, you must assign it a unique number. There are two ways of doing this:

• internal number assignment

In this case, a number within the number range interval allowed is assigned by the SAP R/3 System.

• external number assignment

Here, the user assigns a number within the number range interval allowed. You can define the intervals for external number assignment numerically and alphanumerically.

TATRA  uses external number ranges.
