Disable editing fields in MM02


I would like to lock the field MARA-MSTAE in the basic data 1 in material document MM03, in order not to fill it with any value.

Thanks for helping.


Hello Iba,

Yes, It is possible to change the filed: you can set as optional/Mandatory/Hide/Display and Save the changes against to your tcode.

Please follow the below step

   enter the field and find out the filed selection group number.

2. Go to T-code: OMS9

Insert the filed selection group number 155 (MARA-MSTAE),

Choose the filed ref MM01/MM02,  select the filed optional/Mandatory/Hide/Display as per your requirement and Save the changes.

Please refer below attached thread for your reference.
