I am practising in Ides 4.7 and have a very astonishing situation. I have created materials for my plant/sales org and dchnl. the required entries are existing in table mark and mvke.I can create the sales order by directly entering the material codes (No exception Thrown) in line items but when I am trying to select the materials through matchcode screen entering my sales org and Dcnl a message appears stating "No Values for this selection" can some one can tell what is missing.
In the match code which tab are you selecting. It is important to select the right tab. Try with sales material by description.
