• Validations

• It is ensured that no duplicate mapname entries are entered.

3. Click on the Mapping details tabsheet to enter the details of map header entries.

4. In the Map Header entries we enter the source and destination DDIC structures.

• Map Header entries

• The combination of transaction and table entries is checked, if a segment structure exists (SEG_DD) for that combination.
• When Transaction name is blank, the table name column takes either a DDIC structure name or a transparent table name. Its existence is checked.
• When a DDIC segment structure name (SEG_DD) is entered, the tool automatically maps the structure to Transaction name and Table name.
• Input type field should contain the value either ‚I‘ or ‚S‘, which signifies ITAB processing or Structure processing for the mapping. Normally we enter ‚I‘ which is for ITAB processing.
• Map Order should be numeric and no two entries are allowed to have the same map order.
• When a map name is deleted, all the relevant entries in Map Header table SMO9_SMAP1 and the Map Details table SMO9_MDTL1 are deleted.
• When a Map Header row is deleted, all the entries in the Map Details table SMO9_MDTL1 are deleted.

5. Press on the Save button to save the Map Header.

6. Pressing the Save button would create map entries in the tables on Data Element level. To view the result of the Data Element mapping click on the Map Fields Details tabsheet.
7. If map entries other than the Data Element need be done or functions and conditions for the mapping need to be applied, click on the Map Fields Details tabsheet.

• Source Field is the name of the source field in the source structure entered in the previous tab. Source fields can be concatenated like STREET+KTOKD.
• Destination Field is the name of the field in the destination table structure entered in the previous tab.
• The Forward function and Reverse function columns specify the functions that could be applied for the source field before mapping to destination field.
• Constant column assigns constant value specified to the destination field.
• Forward Condition & Reverse Condition columns specify the conditions which could be applied for mapping in the forward and reverse direction. The field name specified should belong to the source structure. The format for specifying conditions is &IPSTRU-<field name> = <value> e.g. &IPSTRU-KTOKD = ‘CONT’ or &IPSTRU-<field name> = &IPSTRU-<field name> e.g. &IPSTRU-KTOKD = &IPSTRU-SOURCE.
• Append Destination column indicates whether contents of source field are to be appended or overwritten to the destination field. A tick in this check box means the contents of source fields would be appended to destination field.
• Forward Mapping and Reverse Mapping column suggest that this particular mapping code be generated for the forward map or reverse map. A tick in this check box means that, this map would be done for the direction in which the check box is checked.
• The contents of Map Comment column would be appended as comments to the generated mapping code

 The following are the valid functions that can be applied in source field.

• SUBSTR( start, length )

• COMPACT( )

• TRIMSTART( )
• TRIMEND( )
• TRIMALL( )
• LEFTJUSTIFY( )
• RIGHTJUSTIFY( )
• PADR( C )
• PADL( C )
• TOUPPER( )
• TOLOWER( )

8. Click on the Save button when finished with editing of mapping field details
9. Click on the List of mapping tabsheet to go to the initial screen.

10. Click on the Single Map Generate button to generate code for the newly created mapping.
