Business Partners Maintenance is set up in AREA MENU BUPT - Business Partner: Task Menu
All fields, views, sections and screens for BUP1/2/3 are maintained in here. The Functional Team will maintain the master data, but usually request the Technical Team to apply conditional layout changes.
The following steps must be followed to set up a new screen/section in BUP1/2/3:
1. Create a new custom screen in relevant function group with relevant new fields required.
2. Under the same function group, create a function module to do the validations on the screen.
3. BUS23 - Data Sets. Create a new data set name for your custom screen/section.
4. BUS2 - Field groups. Add your screen fields that you want to group together by authorisations or by screen/section and mark whether they should be input fields and required or not.
5. BUS3 - Views. Add a view name for the fields you entered and double click on the entry. Enter your dataset name (created in 3.) and the new screen (created in 1.) name. If you click on "Further Checks" on the left hand side, you can enter your screen Validation module name.
6. BUS4 - Sections. Here you can link the section to the view (created in 5.)
7. BUS5 - Screens. Here you can link the section to a screen. You can either create a new screen if it is a new tab you added, or else you can link a section to an existing screen.
8. BUS6 - Screen Sequence. Once the screen is created, you can sequence the screens in the required order.
9. BUS7 - Business Data Toolset (EVENTS)
These events are used to control your new fields in BUP1/2/3
