Hi,
Its depend on which procedure you have done for material blocking.
If you have block for "X-plant matl status" on basic data 1 tab.
Then you can see the blocked material from table MARA, with filtering value 01 or 02 for field MSTAE.
If you have block for "Plant-sp.matl status" on purchasing tab,
Then you can see the blocked material from table MARC, with filtering value 01 or 02 for field MMSTA
And if you used MM06 for deletion flag for material,
Then you can see the blocked material from table MARA, with filtering value X for field LVORM.
