Example of Processing an IDoc

The Example Program for Processing an IDoc shows how the fictitious message type XAMPLE, which was passed with IDocs of type XAMPLE01, is processed using the inbound function module IDOC_INPUT_XAMPLE. The IDoc type has a header segment, E1xhead, and any number of item segments E1xitem. The data from the IDoc is written to two database tables, XHEAD and XITEM respectively. XHEAD and XITEM contain the same field names as E1xhead and E1xitem respectively. The fields names and data types are shown in the following two tables:

Field Name in XHEAD	Meaning	Type in e1xhead	Type in XHEAD
Docmnt_no	Document number	CHAR	NUMC
Date	Date	CHAR	DATS
Currency	Currency	CHAR	CUKY
Country	Country	CHAR	CHAR

Field Name in XITEM	Meaning	Type in e1xitem	Type in xitem
Item_no	Item number	CHAR	NUMC
Materialid	Material number	CHAR	CHAR
Descript	Material description	CHAR	CHAR
Unit	Measurement unit	CHAR	UNIT
Quantity	Amount	CHAR	QUAN
Value	Value	CHAR	CURR
Ship_Inst	Shipping instructions	CHAR	UNIT

The data in the database is assigned a new document number (field DOCMNT_NO) by means of number assignment. The field DOCMNT_NO is not stored in the newly created table XHEAD.
