Hi,

somebody is locking your valuation area for a material (Table MBEW). If possible, throw everyone else out of the system and try again. It's a good practice to find a time slot to set ML productive, when nobody else is on the system.

Kind regards

Hi Chirstoper,

first, you need to reset 'activate Material Ledger', using Tcode OMX1.

deactivate check list button and save. and try activate again and save.

CKMSTART will run succesfull for your valuation area.

Good Luck

In processing options - Select BACKGROUND PROCESSING (immediate) and execute. The ML will be set as productive!

You will not face any issue.
