But there are not many documents which describes the complete cycle of reading GOS object and display it into adobe form dynamically. The idea of this document is to build a complete cycle of reading a GOS attachment and then embed it into SAP Adobe form.
Limitations & Restrictions: This document is to read GOS picture attachments and embedding it into SAP adobe form. As, I have tried for reading a .PDF GOS attachment and embedding it into SAP Adobe form but as per my knowledge SAP doesn’t provide such solutions till now. So, this is restricted to picture format (.JPG, .GIF, .BMP and .PNG etc.). For (.TIFF & .TIF) picture format first we have to convert from .TIF to .JPG format.
Business Requirement & Descriptions: In this document I will read GOS attachments which are quality certificates and display the quality certificates into SAP Adobe form. This is applicable for other transactions which have got generic object service.
Create a structure & table type which will be sent to SAP adobe form as an import parameter.
Create table type:
Building the program:
REPORT zabhi_gos_attachment_read.

lv_line TYPE i,

Now build the simple form to test:
Go To SFP: Build an interface ZTEST_I_DYNAMIC_PICTURE and pass the import parameter in INPUT and OUTPUT parameter.
Now Build FORM Context.
Go to Layout:
Create one Image field into Design view and bind it with F_Sring which is the converted image in string format.
Activate it.
Now execute your program. Enter the parameters. Business object and Object key. Here object key is the certificate Number and Business object 'BUS2117'.
If you choose different Business object then you have to give correct object key. To get correct object key you can check the business object in SWO1 transaction.
After executing the output is coming like below.
Reference: I don't want to mention particular documents but I take help on few threads on GOS and Adobe form in SCN to build this document.
Suggestion: Please feel free to suggest.
