Trying to get EDI Invoices working for purchasing

Question

I am trying to setup inbound Invoice processing using an INVOIC01 IDOC, Process Code INVL.
As far as I can tell from my searches on the internet and from other sources, I have a syntactically correct IDOC and all of my config is correct, however I get the following message in workflow when I try and load the IDOC:
Item 00010 for purchasing document 4500321129 not selectable
I am a novice to the MM side of things, and am not sure exactly what this line means. I am testing against asingle line order. Using WE19, I see the following:
On the E1EDP01
Document item        00010     
Action                         
Item Category        0         
Order ackn.req.                
Quantity             1000.000  
Unit of measure      CS        
Quantity             1000.000  
Price UoM            CS        
***. quantity                  
Net price            6.99      
On the E1EDP02
Qualifier            001        
Document             4500321129 
Document item        00010      
Date                            
Time                            
BSARK                           
IHREZ                           
Also, I just want to verify that I am correct in one assumption that I am making. I am assuming that I can bring in a INVOIC01 as a parked invoice against an Purchase Order which has not had the goods receipt. Is this correct?
Thanks, Rick

Answer 1

Richard,
For your line item issue, check the PO/line item to confirm the line item has not been deleted.   If it is an active line item the other thing I would check would be the price (confirm it exists on the pricing conditions) .
During the EDI invoice posting process if the PO/line item is set as GR based-IV the idoc will fail if no GR has been made.   Once the GR has been done, the idoc can be reprocessed manually via BD87 or via a scheduled job.
