Objective: SAP On-Line HELP has a section - "Controls and Control Framework (BC-CI)".
Under this refer "Desktop Office Integration (BC-CI)"
In that section read "The Spreadsheet Interface" thoroughly.

The ides is that once a programmer gets hold of a SpreadSheetInterface Object he/she can use the powerful methods to populate Excel in any way setting sheets, ranges, colours, fonts and ofcourse content.

Create a Function Group ZUTIL

Paste TOP Level code into LZUTILTOP

Create 4 Functionn Modules
ZJNC_START_EXCEL.
ZJNC_ADD_SHEET.
ZJNC_ADD_RANGE.
ZJNC_ADD_TABLE.

ZJNC_START_EXCEL - uses the "secret" screen 2307 which a user does not even see to get hold of a Spreadsheet Interface handle. With this alone a user has virtually unlimited power as he she can call all the methods.

But to make life easier I created 4 simple functions:

ZJNC_ADD_SHEET adds a sheet to a work book

ZJNC_ADD_RANGE adds a range to a sheet

ZJNC_ADD_TABLE adds a internal table to a range with specification of all properties like font colour size bold italic etc. In ABAP Objects, you can only declare tables without headers. Hence TABLE[] syntax ensures Header is Stripped.

It is best to have full geometry in mind and fill in the following sequence

For each SHEET Create 1 RANGE & Populate Data immediately
For each SHEET Reapeat for all Ranges

Before creating a range you will need to consider size based on table.
The no. of Rows & Columns will decide size.
The cumulative rows will gixe the corner co-ordinates.
