Clear negative stock in storage type 921 and 922

Hi All,

We have negative stock for some materials n 921 and 922 storage types., We want clear the negative stock.

All TRs related to 921 are deleted and PCN are manually changed to processed status.

No stock available for the material in IM and also no positive stock in WM, so we are not able to reverse the transfer posting material document.

Please guide me on how to clear the negative stock.

Thanks,

Muru
