Stock inconsistancy in WM while scrapping

Hi Experts,

Stock inconsistancy created between MM and WM

MM posting was done for MT 551 scrapping, shows correct in MMBE

WM stock shows negative stock in LS24 in 9** ST, looks like even before IM-WM MT is configured, posting was done.

Please let me know can we use LX23 for single material.

Thankyou,

Ravi
