Not able to set content type for open text HTTP service while uploading file from SAP CRM system

Hello Experts,

I am trying to upload file in open text environment from sap CRM.

The problem I am facing is I am not able to set the Content Type or mime type for the file I am uploading.

I am using set_content_type method to do this.

Please help me out for this.

Below is some part of the code I have written.

part =  p_http_client->request->if_http_entity~add_multipart( ).

   DATA: lv_value TYPE string.

   CONCATENATE 'form-data; name="file"; filename="' p_filename '";' INTO lv_value."

***CONCATENATE 'form-data; name="file"; filename="' p_filename '"; content_type= "application/pdf" ' INTO lv_value."

   part->set_header_field( name = 'Content-Disposition'  value = lv_value ).

   len = xstrlen( p_is_request-file_content ).

*  CALL METHOD part->set_content_type

*    EXPORTING

*      content_type = p_content_type. "application/pdf

   CALL METHOD part->set_data

     EXPORTING

       data   = p_is_request-file_content

*     offset = 0

       length = len.

Thanks & Regards,
