STEP3: Convert the Mime Type of Attachment into file type by calling function module 'SA_KW_RFC_FILENAME_EXT_GET'
STEP4: Finally pass the binary content fetching from SRM_DOCUMENT_CHECKOUT_CONT_TAB to Function module GUI_DOWNLOAD and download the file to whichever Location you want, here we are downloading the file to Desktop directory.
Below is complete code
Introduction:
Hi All,
In this blog, I am going to explain how to work with Attachments in the Dispute management module(FSCM) through the ABAP code.
There is a requirement where we need to Upload & Download the attachments for the Dispute case in our custom Applications I search for Different blogs to find any function modules or classes that can serve this purpose.
PROCEDURE:
Below is the Step-by-Step Process of how to create/Display Dispute case Attachment
DOWNLOAD DISPUTE CASE ATTACHMENT
STEP1: get the CASE_GUID from SCMG_T_CASE_ATTR table and pass to the Function Module
Functi UDM_DC_CASE_READ to get the attachment details.
STEP2: For each attachment, a Unique GUID will be generated this is DOC_GUID and DOC_CLASS will show Storage Location of Document in SRM (Content Model), these two attributes data we can get from above Function module so loop the LT_ATTACH internal table and get attachment data for each DOC_GUID by calling function module SRM_DOCUMENT_CHECKOUT_CONT_TAB.
REPORT ZCASE_GET_ATTACHMENTS.
PARAMETERS: P_EXTKEY TYPE SCMG_EXT_KEY.
DATA: LV_GUID TYPE SCMG_CASE_GUID,
LV_PATH TYPE STRING,
LV_FILENAME TYPE STRING,
LV_DOCTYP TYPE CHAR10,
LT_ATTACH TYPE UDM_T_CASE_DOCUMENT_LIST.

CREATE DISPUTE CASE ATTACHMENT:
STEP1: Upload the file and convert it into Binary data by using function module GUI_UPLOAD as below.
STEP2: convert this binary data to XSTRING.
STEP3: get the Mime type bypassing the file name to by Calling Function module CV120_GET_MIME_TYPE and convert the xstring to RAW DATA.
STEP4: Prepare File class and File content internal table and Pass to the Function Module UDM_DC_ATTRIBUTES_SET.
Pass the File content to UDM_DC_ATTRIBUTES_SET Function module to create attachment

Conclusion: Using the above code we can create and download attachments in Dispute management(FSCM) MODULE using Function modules like UDM_DC_CASE_READ, SRM_DOCUMENT_CHECKOUT_CONT_TAB, UDM_DC_ATTRIBUTES_SET, CV120_GET_MIME_TYPE etc.
Thanks for reading.
Hope this post would be helpful.
