First way -->  i try to control field selection in material master with MM configurations.

 

Field selection groups : Field selection is effected by field selection groups, we can specify which attribute the fields with Hide -- Display -- Required entry -- Optional entry. We can change the assignment of the fields for material master records to the field selection groups. In standart R/3, there are 240 field selection groups. Sap gives permission customers to create new groups 111-120 reserved by us.

 

Sap provides us a lot of selection field selection influencing factors like Plant -- Material Type --Industry sector -- Procurement type -- Transaction -- Sap Solutions (Retail ,Business solution).

 

SPRO --> Logistics - General --> Material Master --> Field Selection --> Maintain Field Selection for Data Screens

 

For instance ; Field selection group 12 consists of MARA-AESZN , MARA-BLANZ , MARA-BLATT , MARA-ZEIAR ....

 

If you change a selection criteria , all fields of group be affected. Also , fields belong to MARA table , you can not control this fields by plant so they are client level . I change field selection group 12 which field referance C be done required field and save and take request.

 



Please try , go to MM01 , create a material master with industry sector (Chemical industry)



Fields of selection group 12 are required field for C Chemical Industry.



  Second example , i want to control material group individually. MARA-MATKL belongs to field selection group 2 with belowed fields.



 

How can i control only MARA-MATKL ? I want to do optional entry this field for material type ROH.

SPRO --> Logistics - General --> Material Master --> Field Selection --> Assign Fields to Field Selection Groups



 

*Create a new selection group for MARA-MATKL. 111-120 number range reserved for customers, write 111 to selection group and save.



  *After that go to OMSR tcode.



* Please check for material type ROH. We can see belowed screen shoot that material group is required field for ROH .



 

*How can i control MARC-WEBAZ for only plant 1200 ?

Go to OMSR --> Select field referance 001 and copy it.



* Fill field reference with 1200.



 

SPRO --> Logistics - General --> Material Master --> Field Selection --> Define Plant-Specific Field Selection and Plant-Specific Screen Selection



Please check configuration:



*Create a material in 1200 plant.



 

Now, how can i restrict changing of MARA-MSTAE ?

SPRO --> Logistics - General --> Material Master --> Field Selection -->Define Lock-Relevant Fields





 

   Second way --> Transaction Variant based on users.

I refer that document How to Create a Transaction Variant thanks to malharjain

 

   Third way --> Badi - User exit

   Badi --> BADI_MATERIAL_REF, BADI_MATERIAL_CHECK / User exit --> MGA00001

   I refer document a badi example : How to Restrict Change Material Shot Text to Particular User and Material Type Using BADI_MATERIAL_C...


   For creation material referance to other material or default values :

   You can benefit from BADI_MATERIAL_REF

     User Exit MGA00001


   Problem with Customer Exit MGA00001 ( Enhancement for MM01 )

  

   An example for user exit ;  Go to --> CMOD tcode , create a project like a ZMM.



Add MGA00001 to your project.



 

For example : if material type = ROH , i do not want to use valuation class =3100 .

This is a simple control for material master fields.

 



 

Sometimes, you need to do mandatory material master views and some classification fields. For solution please check :

Thanks to tanmay.verma2.

Finally , you can control material master fields with authorization --> Authorization in material master related with material types
