Item 000020 - Delivery split because of conflicting header data (TRAGR 0001<->0002).  How this error can be removed?  What is the reason for such error?

Delivery split can occur for the following reasons.

1. Different delivery dates for line items.
2. Different ship to parties for line items.
3. Different routes for line items.

Check whether the above data are same for all the line items.

The following data may cause to split as two deliveries:

--> Check the shipping points of the two items it may be different.
--> Check the item level partner functions in the Sales order is there different ship to parties available for the two items.
--> Check the Delivering plant of the items.
--> Check the shipping conditions are different for the two items.
--> Check the loading group of the two items.

Go to Material Master, select Sales: General/Plant view and compare for both the materials what is maintained in "Trans.Grp". It should be different. 

Maintain unique value and then retry. Your problem will be solved.

Getting a delivery split based on different customer group at header level. This is not the business requirement. How to still create a single delivery document?
Item 000020: delivery split due to conflicting header data (KDGRP: Z1 <-> Z2) 
Message no. VL033 
Diagnosis 
Item 000020 cannot be shipped in the same delivery with the other items in the document because the header data (KDGRP) is different. The KDGRP item field has the value Z2, but in the delivery checked for concatenation it has the value Z1. 

Delivery split happens because of the customer group also. so as you want to do single delivery, assuming that stock is available for both the materials,  check in the item data the schedule lines, the delivery dates of the line items 10&20 and make sure that both are being delivered on same date. And make the customer group (VBKD - KDGRP ) same for line items 10 & 20 .then single delivery will happen. for both the line items Please check the below:

DELIVERY SPLIT:

Delivery Split depends on the following criteria:

1) Ship to party
2) Delivery date
3) Plant 
4) Shipping point
5) Shipping conditions
6) Transportation group
7) Loading group
8) Item categories of materials

Delivery split happen when the requested quantity by customer is not full met, then the system proposes different delivery dates or schedule lines dates based on material availability.

Example : A sales order is confirmed with 2 schedule lines i.e on 14 feb 2008 and 25 feb 2008

If the first delivery (14 feb 2008) is created and PGI is done this means on this delivery date customer has received the goods.

For the second delivery date ( 25 feb 2008), here you can create delivery only on 25 feb not before this due date, this means on this date goods will reach customer after completing the transportation planning, picking, loading, packing and transit, then in system on 25 Feb we create delivery document with PGI.

Partial Delivery option will be set in customer master record sales area ----> shipping--> partial deliveries.
