Integration of a GOS graphic into an SAP Adobe form
In many SAP objects, Generic Object Services (GOS) can be used to link additional information to the object. In many cases, files (Word documents, Excel sheets), i.a. also graphics are uploaded to the object.
The following section describes how to read a graphic (BMP, JPG, PNG, …) for an SAP object and pass the binary content to the form to be displayed there.
Problem
A graphic from the customer master, here in particular a signature, is to be displayed in an SAP Adobe form “Sales order”. The signature itself was uploaded as an attachment to the generic object service and linked to the customer master. The convention is that the file name of the signature is always the same as the customer number, including leading zeros.
Steps for integrating the GOS graphic in the SAP Adobe form
Step 1) Extend the structure in the form interface
- Structure is extended by a field of type XSTRING (or RAWDATA)
- Here, the content of the graphics file is passed to the form as a binary object
Step 2) Extend the form context with a graphic node
- Extension of the form context by a graphic node of type graphic content
Step 3) Add an image field the form layout
- Include the signature as an image field in the form layout
Step 4) Create a function module to read the GOS graphic
- Transfer of the customer number
- Return the file contents in a field of type XSTRING

The function module can now be integrated into the print program to fill the field of type XSTRING to transfer the file to the form.
