This document discusses how to configure SAP to ensure the correct requirement type and class are created from sales document line items for project deliveries. It explains that transaction CNS0 is for project deliveries while VL01N is for sales order based deliveries, and whether one or the other should be used depends on the configuration and business requirements. Primary differences between the two are that CNS0 does not create requirements while VL01N does, and only VL01N allows for delivery related billing. The document also provides explanations from SAP Note 677169 regarding specific questions about delivery type, availability checks, and filtering components in CNS0.

1. Creating delivery from projects
If the standard settings are ok with you, there may not be any customization required from PS
perspective. But from the sales perpsective , you have to do customization to ensure that sales
document line item creates the risght requirement type which inturn leads to the right requirement
class.
SPRO transactions OVZG & OVZH can be used for this. The documentation for these transactions is
fairly comprehensive.
Only just remember that requirement class can be directly determined from strategy group
maintained in material master MRP3, or MRP group, MRP type / item category --- in that order.
Hence depending on your other settings, sales document type, item category etc have to be
configured to ensure rthe right requirement class.

CNS0 is transaction for project delivery and VL01N is for ales order based dlivery. Which one to
adopt is dependent on the rest of the configuration and business requirement.
Project delivery type is "LP' and default delivery item category type is "DLP'.
Primary difference between project delivery and other deliveries is that project delivery does not
create any requirement (TOR) , whereas in the case of sales order based deliveries, deliveries create

2. requirements. i.e, requirements which were till then emanating from sales orders, emanate from
delivey once a delivery is created.
Another major difference is that with VL01N, you can do delivery related billing, whereas deliveries
created using CNS0 cannot be referenced for billing.
Hence, if there is no billing process involved, CNS0 would be the ideal choice. If mile stone billing is
involved, again CNS0 would be the obvious choice. If delivery related billing is involved, possibly you
may have to go in for VL01N.

Delivery from project (CNS0)
a) How can I change delivery type 'LP' ?
Answer:
Delivery type 'LP' (0VLK) is hard coded and can not be changed.
b) Why is availability check not executed in CNS0 ?
Answer:
Please check whether availability check is switched off by delivery item category (0VLK; indicator
'AvailCkOff').
c) Why does availability check in CNS0 return different quantitites than availability check in network
?
Answer:

3. Availability check is controlled by checking rule and checking group. In CNS0 checking rule is hard
coded to 'B ' for plant stock and 'BE' for individual stock. In network checking rule is defined by order
control (plant/order type/business func.) and might therefore differ from the hard coded checking
rule used by CNS0.
Please be aware that also in SD ATP checking rule for delivery is hard coded with same values.
Please check ATP result with transaction CO09.
d) How can I filter out components in CNS0 ?
Answer:
Please refer to notes 546029 and 891134.
