Returnable Transport Packaging 
Both delivery and return of Returnable Transport Packaging (RTP) material is supported with integrated Notas Fiscal creation.
As in the standard R/3 system, the RTP should have item category LEIH marked in the material master record.
RTP Delivery
Please use the sales order type
Wherever possible, SAP recommends to use this process with separate NF for the RTP.
Enter the RTP material as item in the sales order of type ORB. Delivery and billing follows normal procedures. The RTP price will not be included in the total value of the Nota Fiscal.
It is also possible to add the RTP item during delivery only. In this case, the SD tax code will be filled automatically only if saved in the customer-material info.
RTP Pickup
RTP returns orders have to be created separately from the returns orders of regular material, even if they are returned with a single Nota Fiscal.
The RTP returns orders cannot be created with reference to the previous billing document. Thus, you have to enter customer, RTP material, and returned quantity manually in all RTP returns orders.
In the purchase order number field, enter the number of the previous billing document that was created when the RTP was sent to the customer.
Use order type LAB, and enter the Nota Fiscal number of the reference Nota Fiscal in the reference no. field.
In the case of returns with customer NF, use the order type RTEB, and fill in the fields PO date and reference no. as in the case of regular returns with customer NF. It is necessary to create a separate order of type REB as usual for the non-RTP materials.
In case of returns with own NF, use the order type RTOB, and enter the Nota Fiscal number of the reference Nota Fiscal in the reference no. field. It is necessary to create a separate order of type ROB as usual for the non-RTP materials.
As with regular returns.

If you need to produce a single Nota fiscal for the returns of RTP with other material, make sure that the shipping conditions are the same for the original order type and the RTP returns orders RTEB and RTOB, and that the customer NF number has exactly the same format in return orders REB and RTEB.
