references
Use
When material master records are maintained,
the field reference determines for each field selection group if the field selection group is set to
Hide, Display,
Required entry , or Optional
entry.
In Customizing for the Material
Master, you can assign one or more of the following to a field
reference:
You do this in the
activity
You do this in the
activity
You do this in the
activity
The following are already assigned to field
references. These assignments cannot be changed.
The transaction
field reference is normally the same as the transaction code, except for
transactions for creating materials of a particular material type, all of
which are assigned to the field reference MM01. If a material is created or
changed by ALE, the transaction field reference MAL1 or MAL2 is used instead
of MM01 or MM02 respectively.
For materials
procured externally, the field reference F is always
used. For materials produced in-house, the field reference
E is always used.
The system determines whether a field is hidden
or displayed, or whether an entry is mandatory or optional as
follows:
1. It checks whether the plant, material type, industry sector,
transaction, or procurement type are assigned to a field reference. It also
checks the following field references:
- All field references with the prefix
SAP
These field
references are valid client-wide and must not be changed.
This field reference
is also valid client-wide, but may be changed.
2. For these field references, it determines whether the field
selection group to which the field is assigned is set to
Hide, Display, Required
entry, or Optional entry. These
settings have the following priority (1 = highest):
| Setting |
Priority |
| Hide |
1 |
| Display |
2 |
| Required entry |
3 |
| Optional entry |
4 |
1. The system uses the setting with the highest priority.
Example
The field selection group is 010 and the field references and field options
are as follows:
| Field reference |
Field option |
| Ind. sector M |
Optional field |
| Transaction MM03 |
Display |
| Plant 0002 |
Hide |
|
In this case, all
fields assigned to field selection group 010 are hidden since the field option
Hide has a higher priority than
Display or Optional
entry.
Dependencies
Field references are defined in Customizing for
the Material Master in the activity Maintain Field Selection for Data Screens .
