Programmatically copy DOKNR (Document Number) along with its content
There may be a requirement wherein developer have to PROGRAMMATICALLY create a copy of existing DOKNR (Document Number) along with its content i.e. copying all the files/originals existing within the DOKNR and creating new FILE ID for each newly created file.
Document is in context to DMS content management system, which can be accessed via TCODE CV01N, CV02N etc.
Pictorial view for the requirement is below:
Challenges
- No FM available which can directly perform this task.
Understanding on:
- DMS server
- ABAP
Facts
- Authorization for Read/Write operation on DMS content management system.
Steps
- Reading files from Previous Document Number (DOKNR)
| Action Taken | Call FM CVAPI_DOC_GETDETAIL with importing parameter as OLD_DOKNR |
| Code Snippet | CALL FUNCTION ‘CVAPI_DOC_GETDETAIL’ EXPORTING pf_dokar = DOKAR (Document Type) pf_doknr = OLD_DOKNR pf_dokvr = ’00’ pf_doktl = ‘000’ TABLES pt_files = lt_files_previous EXCEPTIONS not_found = 1 no_auth = 2 error = 3 OTHERS = 99. |
| Outcome | LT_FILES_PREVIOUS parameter will have list of all the files inside DOKNR |
- Reading the content of individual file
| Action Taken | Call FM CVAPI_DOC_CHECKOUTVIEW with importing parameter as OLD_DOKNR. Loop at outcome of Step1 and pass reference of individual FILE through LT_FILES_PREVIOUS_IND. |
| Code Snippet | CALL FUNCTION ‘CVAPI_DOC_CHECKOUTVIEW’ EXPORTING pf_dokar = DOKAR (Document Type) pf_doknr = OLD_DOKNR pf_dokvr = ’00’ pf_doktl = ‘000’ pf_ftp_dest = ‘SAPFTPA’ pf_http_dest = ‘SAPHTTPA’ pf_content_provide = ‘TBL’ IMPORTING psx_message = ls_message TABLES pt_files = lt_files_previous_ind ptx_content = lt_drao_ind. |
| Outcome | LT_DRAO_IND parameter will have content of individual file which is passed through LT_FILES_PREVIOUS_IND |
- Creating a new Document number (DOKNR)
| Action Taken | Call FM CVAPI_DOC_CREATE with importing parameter as Document Type / Storage Category / TCODE. |
| Code Snippet | ls_draw-dokar = DOKAR (Document Type). ls_draw-dokvr = ’00’. ls_draw-doktl = ‘000’. ls_draw-dokst = ‘IA’. lv_storage_cat = ‘DMS_C1_ST’. ls_api_ctrl-tcode = ‘CV01N’. CALL FUNCTION ‘CVAPI_DOC_CREATE’ ps_draw = ls_draw ps_api_control = ls_api_ctrl IMPORTING psx_message = ls_message pfx_doknr = lv_documentnumber. |
| Outcome | Post execution of FM, lv_documentnumber will have newly created DOKNR. |
- Creating the content of individual file
| Action Taken | Loop at DRAO internal table and populate DOKAR/DOKNR/DOKVR/DOKTL with relevent values. Additionally also populate APPNR (Application number) which is available from TABLE parameter “PT_FILES” inside FM CVAPI_DOC_CHECKOUTVIEW. |
| Code Snippet | LOOP AT lt_drao_ind ASSIGNING <fs_drao>. <fs_drao>-dokar = DOKAR (Document Type). <fs_drao>-doknr = NEW_DOKNR. <fs_drao>-dokvr = ’00’. <fs_drao>-doktl = ‘000’. <fs_drao>-appnr = ls_files_previous_ind-appnr. ENDLOOP. |
| Outcome |
- Attaching the new file to DOKNR
| Action Taken | Call FM CVAPI_DOC_CHECKIN with importing parameter as NEW_DOKNR |
| Code Snippet | CALL FUNCTION ‘CVAPI_DOC_CHECKIN’ EXPORTING pf_dokar = DOKAR (Document Type) pf_doknr = NEW_DOKNR pf_dokvr = ’00’ pf_doktl = ‘000’ ps_api_control = ls_api_ctrl pf_content_provide = ‘TBL’ pf_ftp_dest = ‘SAPFTPA’ pf_http_dest = ‘SAPHTTPA’ IMPORTING psx_message = ls_message TABLES pt_files_x = lt_files_previous_ind pt_comp_x = lt_comp_x pt_content = lt_drao_ind. |
| Outcome | Post execution of FM, LT_FILES_PREVIOUS_IND will have new file id created. |
Note: In Step section wherever BOLD/ITALIC is used or variables which are used, that needs to be defined and managed.
