Procurement Type

Hi Experts,

For ERSA material type, I am seeing the Procurement Type field in MM01 in display mode. How do you make it in edit mode in MM01?

I did check T-code: MMD2 but there are no values in it. In OMS9 for selection group 55, i see it in display mode only for MM03 and MMVD.

Thank you.
