OLE (Object linking and embedding) in SAP is used to integrate MS-excel and MS-word eand to achieve automation through programming interface . When called from an ABAP program, the SAPGUI acts as OLE client, and the desktop application as the OLE server.

In general there are five basic statements to achieve automation:

  • CREATE OBJECT
  • SET PROPERTY
  • GET PROPERTY
  • CALL METHOD
  • FREE OBJECT

1. Creating an OLE Object

To create an OLE object, the ABAP statement “CREATE OBJECT” is used.

The syntax is CREATE OBJECT obj class.

Here, “obj” is the handle variable for the base object and “class” is the specific identifier for the corresponding application.

  1. e.g. CREATE OBJECT gs_word ‘WORD.APPLICATION’ .

If the creation is successful the value of “sy-subrc” becomes “0”, otherwise it becomes some other value (i.e. “1”, “2” or “3” with respect to the error type).

2. Calling a Method of an Object

After creating an OLE object, it is possible to call its methods to execute its functionality. This is achieved by using the ABAP statement “CALL METHOD OF”. Also the required  parameters can be passed using this statement.

The syntax is:CALL METHOD OF obj m [= f] [EXPORTING p1 = f1 … pn = fn] .

Here, “obj” is the object handle variable, “m” is the method name, “f” is the variable where the output of the method will be replaced and “pn = fn” assignments are used to pass parameters. The “EXPORTING…” part must be at the end of the statement. For the moment, parameter passing is done by giving their positions and the corresponding value.

  1. e.g. CALL METHOD OF gs_word ‘Documents’ = gs_documents .

CALL METHOD OF gs_selection ‘TypeText’ EXPORTING #1 = ip_text .

Successful method calls makes “sy-subrc” value “0”, and unsuccessful cases make it some other value.

3. Setting a Property of an Object

To set a property of an OLE object, the ABAP statement “SET PROPERTY OF” is used.

The syntax is: SET PROPERTY OF obj p = f .

Here, “obj” is the object handle variable, “p” is the property name and “f” is the value to be assigned.

  1. e.g. SET PROPERTY OF gs_word ‘Visible’ = 1 .

Operation result status is indicated at the system variable “sy-subrc”; “0” for successful operations and another value for erroneous cases.

4. Getting a Property of an Object

Getting the value of a property of an OLE object is obviously similar to setting it. For this, the ABAP statement “GET PROPERTY OF” is used.

The syntax is: GET PROPERTY OF obj p = f .

Here, “obj” is the object handle variable, “p” is the property name and “f” is the variable to which the value of the property is assigned.

  1. e.g. GET PROPERTY OF gs_view ‘Type’ = gv_viewtype .

Again, operation result status is indicated at the system variable “sy-subrc”; “0” for successful operations and another value for erroneous cases.

5. Freeing an Object

Generally for performance issues, it is required to free the memory allocated for OLE objects. For this, the ABAP statement “FREE OBJECT” is used.

The syntax is: FREE OBJECT obj. where “obj” is the object handle variable.

6. NO FLUSH Addition

Normally, OLE statements are buffered by the ABAP processor and executed at the frontend collectively before the first statement which is not of OLE context. Using this addition prevents this and postpones the execution till just before the first non-OLE statement coming after an OLE statement without NO FLUSH addition.
