Scenario: Sales Order Creation (VA01)<\/strong><\/h3>\n

Business Requirement:<\/strong>
When creating a Sales Order<\/strong>, the company wants to block the order if the customer has overdue invoices<\/strong>.<\/p>\n

\n

Solution with Enhancement (Recommended)<\/strong><\/h3>\n
    \n
  • \n

    Use a User Exit<\/strong> or BAdI<\/strong> (e.g., USEREXIT_SAVE_DOCUMENT<\/code> in program MV45AFZZ<\/strong>).<\/p>\n<\/li>\n

  • \n

    In the exit, add custom logic to check customer overdue status from tables BSID\/BSAD<\/strong>.<\/p>\n<\/li>\n

  • \n

    If overdue invoices are found \u2192 issue an error message and stop the save.<\/p>\n<\/li>\n<\/ul>\n

    Result:<\/strong> Standard SAP program stays intact. Upgrade-safe.<\/p>\n<\/p>\n

    IF lv_overdue = ‘X’.
    MESSAGE e001(zmsg) WITH ‘Customer has overdue invoices. Sales Order cannot be saved.’.
    ENDIF.<\/p>\n<\/p>\n

    Solution with Modification (Not Recommended)<\/strong><\/h3>\n
      \n
    • \n

      Directly change the standard SAP program SAPMV45A<\/strong>.<\/p>\n<\/li>\n

    • \n

      Insert custom code inside the SAVE_DOCUMENT<\/code> routine itself to check overdue invoices.<\/p>\n<\/li>\n

    • \n

      This alters SAP\u2019s original code.<\/p>\n<\/li>\n<\/ul>\n

      Risk:<\/strong><\/p>\n

        \n
      • \n

        After a system upgrade, SAP may overwrite your changes.<\/p>\n<\/li>\n

      • \n

        You\u2019ll need to re-implement modifications manually, increasing maintenance cost.<\/p>\n<\/li>\n<\/ul>\n

        Key Difference in This Example<\/strong><\/h5>\n
          \n
        • \n

          Enhancement:<\/strong> Code added in a user exit (safe extension point)<\/strong> \u2192 future upgrades won\u2019t break it.<\/p>\n<\/li>\n

        • \n

          Modification:<\/strong> Code inserted directly into SAP standard program \u2192 risky during upgrades.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","question-category":[158],"question_tags":[178,293,419,177],"class_list":["post-7836","question","type-question","status-publish","hentry","question-category-abap","question_tags-abap","question_tags-enhancement","question_tags-modification","question_tags-sap"],"_links":{"self":[{"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=\/wp\/v2\/question\/7836","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=\/wp\/v2\/question"}],"about":[{"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=\/wp\/v2\/types\/question"}],"author":[{"embeddable":true,"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=7836"}],"wp:attachment":[{"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7836"}],"wp:term":[{"taxonomy":"question-category","embeddable":true,"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=%2Fwp%2Fv2%2Fquestion-category&post=7836"},{"taxonomy":"question_tags","embeddable":true,"href":"https:\/\/www.sapewmhelp.com\/index.php?rest_route=%2Fwp%2Fv2%2Fquestion_tags&post=7836"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
