Conversion Rules 

When passing parameters, conversion is always via character type:

The ABAP-type is converted into CHAR according to ABAP-conventions. Afterwards, the CHAR is converted into OLE by using the corresponding OLE types:

ABAP-Type ® CHAR ® OLE type

Without Typeinfo, or if the OLE type is undefined, it is set according to the ABAP type as follows:

ABAP types

OLE types

I

Int

P,F

Double

D

Date

T

Time

otherwise

Character

 

At present, the maximum length of character variables is restricted to 255.

With some objects the semantics of the parameters depends on the OLE type (see the documentation of the server application).
