I get the error Account determination for 2000 WRX is not possible when trying to post a Goods Receipt for a material without a master.
My material is linked to material material type 1.
Material type 1 is linked to valuation class 3000.
In OBYC transaction WRX valuation class 3000 is linked to the G/L account I am posting to 405200.
Despite these settings I cannot post a good receipt.
The posting however works when I use a material with a material master and the same G/L account.
