Define Number Ranges for Each Material Type

Use

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 system. Currently, the maximum length allowed for an internal number is 18.

• 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. For integration purposes, SAP, currently, allows only the number range length of 18 characters.

You define the number range intervals for so-called groups. You assign one or more material types to each group.

• If you assign just one material type to a group, you can define both an internal and an external number range interval for the material type.

• If you group together more than one material type, you can define an internal and an external number range interval here too. This allows several material types to have the same number range intervals.

In the step Define attributes of material types, you have defined as an attribute of the material type whether, with external number assignment, a check is to be made against the number range.

SAP recommends using internal number assignment. Since you can use matchcodes to select materials according to any desired criteria, it is not normally necessary to use a mnemonic external number.

However, external number assignment can be advantageous if you want to use your materials in other systems outside the SAP system. However, the field Old material number and a matchcode are also available as standard for this purpose.

1. Assign each material type to a group. Remember that you can also group together more than one material type.
2. Define the number range intervals for each group.

If you have not assigned a particular material type to a group, you can only use it if, in the material type, you allow external number assignment without a check against the number range.
