Screen exit for MM01 to add additional fields to basic data tab .

Question

Hi All ,
We are working on the SAP version ECC 5.0 . Our requirement is to add additional fields to the general data section of the basic data1 tab for the tcode MM01 . I have gone through many previous queries in SDN but not able to figure out what exactly the process should be . All I could figure out is to start the process from appending the structure to MARA for the additional fields . Then follow the steps in the SPRO .
Define Structure of Data Screens for Each Screen Sequence
Assign Secondary Screens
Maintain Order of Main and Additional Screens
Assign Screen Sequences to User/Material Type/Transaction/In
Define How Maintenance Statuses Are Determined in Data Trans
Create Program for Customized Subscreens
I am not able to comprehend what we are trying to do in these steps .
Can anyone explain me in detail what we are trying to do in the whole process ?
Thanks ,
Varun .

Hi varun,
Create the append structure on the MARA table.
The SAP note 44410 describes how to add the new fields to the screen and how the updating will work.
1.     Make a copy of function group MGD1to ZMGDI as stated inthe Ossnote using program COPYMGDI.
2.             Goto Se38 enter program name SAPLZMGDI Click Display and goto> program-> other object---> enter screen number '0001' and add your fields to the subscreen which should apper on the the general data section of the basic data1 tab for the tcode MM01
2.     Make the changes stated in SAP Note.
3.     After make the changes the functional analyst will need to make some configuration changes.
4.     SPRO -> Logistic General -> Material Master -> Configuring Materal Master -> Define Structure of Data Screens Sequence.
5.     Select SSq = 21 then click on Subscreens select Basic DATA1
6.     Enter in the new screens that were built
7.     Change the row that was create putting in the program (function group program) that was created in step 2.
