Partial goods issue for a consumption Outbound Delivery in SAP EWM

Hello SAP Gurus, 

I americium faced with the pursuing situation: 

A Production Order has 2 components A and B.

Staging petition is made to determination some the components to the PSA. However the staging petition for lone 1 constituent A has been fulfilled. 

When this bid is confirmed, strategy creates a depletion OBD. There is simply a PPF that tries to station the GI for for the OBD, but, it fails to station the GI arsenic it cannot find the banal of constituent B successful the PSA. 

Now, the concern wants to astatine slightest beryllium capable to station the GI for the constituent that has been staged (in this illustration constituent A). At this point, the OBD should determination to the GI presumption 'partially completed'. Later, erstwhile they corroborate the staging of constituent B, they say, they should beryllium capable to station the GI again - this clip consuming the constituent B, and moving the wide papers to GI presumption 'completed'. 

In SPRO -> EWM -> GI Process ->  Outbound Delivery -> Production Supply -> 'Post Goods Issue for depletion posting', the fields 'Aut GI CPD' and  'Pst Par GI' are marked for my warehouse. 

I besides referred to the SAP Note 2353305 connected this issue, but this enactment besides talks astir the supra configuration, which I already person set. 

Any idea, wherefore the partial GI whitethorn not beryllium working? 

Thanks successful advance
