Prepare SAP BOM

The SAP on Azure Deployment Automation Framework uses a Bill of Materials (BOM). The BOM helps configure your SAP systems.

The automation framework's GitHub repository contains a set of Sample BOMs that you can use to get started. It is also possible to create BOMs for other SAP Applications and databases.

If you want to generate a BOM that includes permalinks, follow the steps for creating this type of BOM.

Note

This guide covers advanced deployment topics. For a basic explanation of how to deploy the automation framework, see the get started guide instead.

Prerequisites

Scripted creation process

This process automates the same steps as the manual BOM creation process. Review the script limitations before using this process.

  1. Navigate to your stack files folder.

    cd stackfiles
    
  2. Run the BOM generation script. Replace the example path with the correct path to your utilities folder. For example:

    cd ~/Azure_SAP_Automated_Deployment/deploy/scripts/generate_bom.sh >../bom.yml
    
  3. For the product parameter (product), enter the SAP product name. For example, SAP_S4HANA_1809_SP4. If you don't enter a value, the script attempts to determine the name from the stack XML file.

  4. Open the generated bom.yml file for review.

  5. Review the templates section (templates). Make sure the file and override_target_location values are correct. If necessary, edit and comment out those lines. For example:

    templates:
      # - name:     "S4HANA_2020_ISS_v001 ini file"
      #   file:     S4HANA_2020_ISS_v001.inifile.params
      #   override_target_location: "{{ target_media_location }}/config"
    
  6. Review the stack files section (stackfiles). Make sure the item names and files are correct. If necessary, edit those lines.

Script limitations

The scripted BOM creation process has the following limitations.

The scripting has a hard-coded dependency on HANA2. Edit your BOM file manually to match the required dependency name. For example:

dependencies:
  - name: "HANA2"

There are no defaults for the media parameters override_target_filename:, override_target_location, and version:. Edit your BOM file manually to change these parameters. For example:

   - name:     SAPCAR
     archive:  SAPCAR_1320-80000935.EXE
     override_target_filename: SAPCAR.EXE

   - name: "SWPM20SP07"
     archive: "SWPM20SP07_2-80003424.SAR"
     override_target_filename: SWPM.SAR
     sapurl: "https://softwaredownloads.sap.com/file/0020000001812632020"

The script only generates entries for media files that the SAP Maintenance Planner identifies. This limitation occurs because it processes the stack .xsl file. If you add any files to your download basket separately, such as through SAP Launchpad, you must add those files to the BOM manually.

Manual creation process

You can create your BOM through the following manual process. Another option is to use the scripted creation process to do the same steps.

  1. Open the downloads folder you created for acquiring SAP media

  2. Create an empty YAML file named bom.yml.

  3. Open bom.yml in an editor.

  4. Add a BOM header with names for the build and target. The name value must be the same as the BOM folder name in your storage account. For example:

    name:    'S4HANA_2020_ISS_v001'
    target:  'ABAP PLATFORM 2020'
    
  5. Add a defaults section with the target location. Use the path to the folder on the target server where you want to copy installation files. Typically, use {{ target_media_location }} as follows:

    defaults:
      target_location: "{{ target_media_location }}/download_basket"
    
  6. Add a product identifiers section. You populate these values later as part of the template preparation. For example:

    product_ids:
      scs:
      db:
      pas:
      aas:
      web:
    
  7. Add a materials section to specify the list of required materials. Add any dependencies on other BOMs in this section. For example:

    materials:
    dependencies:
        - name:     HANA2
    
  8. Get a list of media to include in your BOM.

    1. Open your download basket spreadsheet. This file renders as XML.

    2. Format the XML content to be human readable, if necessary.

    3. For each item in the download basket, note the String and Number data. The String data provides the file name (for example, igshelper_17-10010245.sar) and a friendly description (for example, SAP IGS Fonts and Textures). You'll record the Number data after each entry in your BOM.

  9. Add the list of media to bom.yml. The order of these items doesn't matter, however, you might want to group related items together for readability. Add SAPCAR separately, even though your SAP download basket contains this utility. For example:

    media:
        - name:     SAPCAR
          archive:  SAPCAR_1320-80000935.EXE
    
        name: "SAP IGS Fonts and Textures"
          archive: "igshelper_17-10010245.sar"
          # 61489
    
        <...>
    
  10. Optionally, if you need to override the target media location, add the parameter override_target_location to a media item. For example, override_target_location: "{{ target_media_location }}/config".

  11. Add a blank templates section.

    templates:
    
  12. Create a stack files section. For example:

    stackfiles:
      - name: Download Basket JSON Manifest
         file: downloadbasket.json
    
      - name: Download Basket Spreadsheet
         file: MP_Excel_2001017452_20201030_SWC.xls
    
  13. Save your changes to bom.yml.

You can automatically generate a basic BOM that functions. However, the BOM doesn't create permanent URLs (permalinks) to the SAP media by default. If you want to create permalinks, you need to do more steps before you acquire the SAP media.

Note

Manual generation of a full SAP BOM with permalinks takes about twice as long as preparing a basic BOM manually.

To generate a BOM with permalinks:

  1. Open DownloadBasket.json in your editor.

  2. For each result, note the contents of the Value line. For example:

         "Value": "0020000000703122018|SP_B|SAP IGS Fonts and Textures|61489|1|20201023150931|0"
    
  3. Copy down the first and fourth values separated by vertical bars.

    1. The first value is the file number. For example, 0020000000703122018.

    2. The fourth value is the number you'll use to match with your media list. For example, 61489.

    3. Optionally, copy down the second value, which denotes the file type. For example, SP_B for kernel binary files, SPAT for non-kernel binary files, and CD for database exports.

  4. Use the fourth value as a key to match your download basket to your media list. Match the values (for example, 61489) with the values you added as comments for the media items (for example, # 61489).

  5. For each matching entry in bom.yml, add a new value for the SAP URL. For the URL, use https://softwaredownloads.sap.com/file/ plus the third value for that item (for example, 0020000000703122018). For example:

    - name: "SAP IGS Fonts and Textures"
      archive: "igshelper_17-10010245.sar"
      sapurl: "https://softwaredownloads.sap.com/file/0020000000703122018"

Validate BOM

You can validate your BOM structure from any OS that runs Linux-type commands. For Windows, use Windows Subsystem for Linux (WSL). Another option is to run the validation from your deployer if there's a copy of the BOM file there.

  1. Run the validation script check_bom.sh from the directory containing your BOM. For example:

    cd ~/Azure_SAP_Automated_Deployment/deploy/scripts/check_bom.sh bom.yml
    
  2. Review the output.

Successful validation

A successful validation shows the following output. You already installed yamllint and ansible-lint commands in the prerequisites.

... yamllint [ok]
... ansible-lint [ok]
... bom structure [ok]

Unsuccessful validation

An unsuccessful validation contains error information. For example:

../documentation/ansible/system-design-deployment/examples/S4HANA_2020_ISS_v001/bom_with_errors.yml
  178:16    error    too many spaces after colon  (colons)
  179:16    error    too many spaces after colon  (colons)
  180:16    error    too many spaces after colon  (colons)
    
... yamllint [errors]
... ansible-lint [ok]
  - Expected to find key 'defaults' in 'bom' (Check name: S4HANA_2020_ISS_v001)
  - Unexpected key 'default in 'bom' (Check name: S4HANA_2020_ISS_v001)
  - Unexpected key 'overide_target_location in 'bom.materials.stackfiles' (Check name: Download Basket Stack text)
... bom structure [errors]
