Handling Data in Excel In-place Display Using BDS The article demonstrates data handling in excel in-place display using BDS with the help of a program. The demo program maintains the entries in a database table through an excel in-place display. OVERVIEW MS Excel is the conventional way of storing and maintaining data. Sometimes, user prefers to display report output in specific MS Excel templates; which contain logos, user specific table formats, engineering drawings, diagrams and macros. The data modified manually in these excel templates may be again transferred to SAP for processing. Excel integration is required due to various reasons like avoiding user training on newly developed custom programs and screens, use existing data templates, data integration with legacy system. BDS (Business Document Services) is a convenient option for excel integration as user specific MS Excel templates can be stored in it. These templates can be called in an <strong>ABAP</strong> program at runtime to display data. Also, the data modified by the user in MS Excel can be read into <strong>ABAP</strong> program for processing. The functionality will be demonstrated through a demo program. The program will display the content of a custom table in excel in-place display. The user can change the non key fields displayed and the modified contents will be updated to the table after validation. 1. Defining a B DS Class A custom BDS class can be defined through transaction SBDSV1 as described below. An existing BDS class can be used, unless the user wants a separate class for a specific application. In SBDSV1, Go to „NEW ENTRIES‟.
Enter the „Class name‟, „Class type‟ as „Other objects(OT)‟, „Log Level‟ as required and rest of the parameters should filled as shown below. 2. Uploading MS Excel Template Design a template as per user requirement in MS Excel. You can embed all static objects/data to be displayed such as logos, drawings, headers etc in the template, except the area, where the data will be filled at runtime. A sample template has been created as shown below.
