One order framework

One Order Object Model
The CRM One Order documents are created in transaction ‘CRMD_ORDER’.
The Header table that is updated by the created document is ‘CRMD_ORDERADM_H’.
The primary key for this table is GUID (Global Unique Identifier). For each document
created, a unique number (GUID) is generated by the system which depends on the
Logical name of the system. The field ‘Object ID’ of table ‘CRMD_ORDERADM_H’
contains the document number.
The Item table for One Order document is ‘CRMD_ORDERADM_I’. Each Item of a
One Order document has a different GUID. The Header GUID of the Item is stored in

field ‘HEADER’ of table ‘CRMD_ORDERADM_I’.
