Answer 1

You can use the multiple account assignment functionality of SAP.
In fact, it is possible to maintain multiple account assignment for each and every PO line item by selecting the 'Multiple Account Assignment' button in the 'Account Assignment' View of the Item Detail of PO. However, for such multiple account assignment selection, no accounting document will be generated upon GR maintenance. This can only be done during IR via LIV process. 
From the accounting point of view, for one particular single line item, it is possible to split into different cost centers or internal orders. For instance, I have ordered 10 pcs of bearings of which 4 will be charged to Cost Center A and the remaining 6 pcs will be posted to cost center B. However, it is of SAP standard feature that once using the multiple-account assignment, no accounting document will be generated after GR posting. They will only be posted when IR is maintained. 
But if you have EHP4 than
As of SAP enhancement package 4 for SAP ERP 6.0 (SAP_APPL 604) business function MM, Multiple Account Assignment (LOG_MM_MAA_1), the following newfunctions for multiple account assignment are available:
o Amount-based distribution even for very small amounts
In addition to percentage and quantity-based distribution, you can now also use amount-based distribution, and thereby distribute the total value of a purchase requisition item or purchase order item to the individual account assignments.
The system also includes very low values that have been assigned to an account assignment. You can use amount-based distribution for the procurement of materials and services.
o Distribution of delivery costs to multiple account assignments
Previously, it was not possible to use multiple account assignment for planned delivery costs for the material items. Provided that you create or change purchase orders with transactions ME21N and ME22N, the system also distributes planned delivery costs to the account assignments on a quantity,percentage, or amount basis, exactly as defined by the distribution key of the
item. It is not possible to distribute delivery costs in a different way to the associated material item. You can display the distribution of delivery costs in the  item detail data.
In the commitment interface, the system distributes the delivery costs to the same account assignment items as the associated material costs. You can use
both quantity-based and value-based commitment management.
Note: For delivery costs with multiple account assignment, you cannot run goods-receipt-based invoice verification.
o Multiple account assignment and valuated goods receipt
Previously, you could only use non-valuated goods receipt when creating items that you wanted to distribute to different account assignments in purchase requisitions and purchase orders. Now you can also use multiple account
assignment for those purchase requisition items and purchase order items where you expect a valuated goods receipt.
Constraint
You cannot use multiple account assignment in stock transport orders.
Effects on Existing Data
The following changes have been made to the user interface:
When creating, changing, and displaying purchase requisitions (transactions ME51N,
ME52N, and ME53N) and purchase orders (transactions ME21N, ME22N, and
ME23N), the Account Assignment tab page in the item detail data contains the new
entry Amount-Based Distribution in the Distribution selection field (program
SAPLMEACCTVI, screen 1000).
