Hi,
Yes, TR means Transfer Requirement Number and TO means Transfer Order. Sorry, I didnt elaborate.
If you enter the stock type as blocked stock while doing GR, system will post the stock to blocked stock, unless otherwise a different stock type QI is defined in the material master - QM view. Please the inspection type set up in your material master QM view.
In standard, if there is no QM inspection type set up, and if you set the stock type as blocked stock in GR, system will post the stock to blocked stock. Correspondingly, the TR will be generated with stock category S (blocked stock) and the same will be visible in GR document - WM tab, as shown below:
Regards,
