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.
Before including customer-defined fields in a field selection group together with standard fields, or assigning standard fields to a different field selection group, familiarize yourself with the assignment of fields to field selection groups in the standard R/3 System.
Standard settings
The values of the field selection groups have been preassigned as follows:
001-110 Material master for industry
111-120 Reserved for customers (except where the values are already in use)
121-150 Material master for industry
151-210 Material master for retail
211-240 Reserved for customers
Recommendation
If possible, use the setting in the standard R/3 System. No further action is then required. If you want to make individual fields inaccessible, the easiest way is to group them together in a single field selection group and to set it to Display or Hide.
Activities
1. Check the setting in the standard R/3 System.
For this, you need to know the data screen on which the relevant field appears in the material master, and the name of the screen field, for example, MARA-MEINS in the case of the base unit of measure.
2. If necessary, change the assignment of fields to field selection groups as required.
Further notes
In the case of long texts, you define whether the entire screen is hidden or displayed, or whether entries are mandatory or optional. For this reason, each screen has been assigned to one of the following dummy fields:
LTEXT_BEST Purchase order text
LTEXT_GRUN Basic data text
LTEXT_IVER Internal comment
LTEXT_PRUE Inspection text
LTEXT_VERT Sales text
