SAP GOS Objects Migration -Download/Upload


Hello Guys, I myself Vivek with 16+ years of rich experience in SAP and specialized in SAP Fiori/UI5 Development.

My major focus will be in the digital transformation projects.

Eligible Readers

SAPUI5 developers, Consultants, Solution Architects and basically anyone is working on Digital Transformation Projects.

When the readers need this blog?

One of the pain point lies in migrating the documents attached to the GOS(Generic Object Services). Most of the older implementations will definitely have utilized the GOS services and migrating them is a cumbersome process.

Once of the ways of migrating the GOS Documents is via downloading and uploading the same. We have tried moving them via IDOCs, but was not a success story in our case the source and target document number varies.

How GOS is linked to a Document?

Let us take a Finance document from transaction FB03 or Service entry sheet from ML81N, Document number is the key and the object type (eg: BKPF, BUS2091) are the important factors.


Object Services

We can get the above information functionally and once we get the above information go to table SRGBTBREL



Please use the above selection and RELTYPE ‘ATTA’ means GOS Document. If the RELTYPE is URL, then it is an external link attached to the document.


Table Fields

INSTID A is the document number field. If it ML81N, service entry sheet number is the INSTID A id. If it is finance document fro, FB03 then it will be <Company code>+<Document No>+<Fiscal Year> and this changes accordingly.

Also please pay attention to the field INSTID B which is the field makes relation to the content of the actual Binary of the file stored in table SOC3.

Now let us see the coding we have made to download the GOS attachment and sequence to be used.

  1. Get the Binary Relation between the document number and the GOS attachment using the instid A, typeid A and Catid A. This will get the INSTID B for the attachment.
  2. Using the INSTID B, call the function module SO_OBJECT_READ
  3. After getting the lt_objcont from the read function module, use the function module SO_OBJECT_DOWNLOAD to download the file.

I am presenting the code below with which you can download all the Business object types.

We have also modified the code for uploading a mapping file with old document number in ECC and New document number in S4HANA.

Download does not complete our job, We have to upload the same in the new system. Let’s continue in Part 2.
