Add fields to material Master (MM01)

[Former Member]

Hi Experts, after checking OMS2, OMS3, OMS9, OMSA...I still have no idea about how to show some fields in my material master data. They belong to group 103 which is assignet to material type FERT and Basic Data 1. They are setup as "Optional" but they are not shown when I try to create a new material.

I expected to find it easy to solve, as when you modify others screen layouts (p.e. Materials Management> Purchasing>Purchasing Info Record-->Define Screen Layout) but it seems not. Any idea?

Thank you

Hi,

Check in SPRO settings for Material type.

Make fields compulsory whatever you want to use.

Thanks

Can you explain it more in depth, step by step and which is the path in SPRO? Thank you

Hello Cristian,

You cannot define the field selection for an individual field, however,

the fields are grouped together in field selection groups.(Customizing

'Assign Fields to Field Selection Groups') The input/output attributes

are determined per field selection group.For the specification of the

properties of a field selection group, there are several criteria. They

are called field selection references.Not only one criterion (= field

selection reference) is relevant for the definition of the field

selection attributes but SIX criteria are.

Some of the field selection references are hard-coded (for example,

transaction) others can be defined (for example, plant, material

type...).In the following, the six field selection references are listed

and also the transactions in which they can be defined.

1. Transaction (MM01, MM02 ....)

2. Industry sector (you can assign the field selection reference to the

industry sector by using Transaction OMS3)

3. Material type (You can assign in field FELDREFERENZ by using

Transaction OMS2.The name of the material type is not automatically

the field selection reference but it depends on what is on field

FELDREFERENZ in Transaction OMS2.If the field is empty, there is no

specific settings for this material type.)

4. Plant (you can assign the reference to the plant in Transaction

OMSA)

5. Procurement-releated field selection references. There are the two

field references E (internal procurement) and F (external

procurement). It depends on the settings in Customizing for the

corresponding material type under 'Internal/external purchase

orders' whether one or which one of the field references is used. If

internal purchase orders are allowed (setting 1 or 2) and external

orders are forbidden (setting 0), the field selection uses E. If

external purchase orders are allowed (setting 1 or 2) and internal

orders are forbidden (setting 0), the field selection uses F. When

both internal and external purchase orders are allowed, the field

selection uses neither E nor F.

6. Customer-specific field reference KB (customer-specific

requirements)

Since a field can have only one attribute at the end (display = '*',

change = '.', hide = '-', required entry = '+') a property must be

determined from these six criteria.You do this by prioritizing the

above-mentioned properties:

The hide function has a greater effect than the display function.The

display function has a greater effect than the required entry function

and the change/ready for input function has the least effect.

If for one of the six mentioned field selection references 'Hide' is

set for the relevant field selection group, all fields which were

assigned to this field selection group are hidden, no matter how the

attributes were set in the other five field selection

references.Therefore, you must always check all six field selection

references.It is not sufficient just to look at one field selection

reference.

If you checked this setting and, however, the field does not have the

display attribute required, then it is possible that the attributes of

the field are hard-coded.

Regards,

Mauro
