SAP R/3 for Everyone: Step-by-Step Instructions, Practical Advice, and Other Tips and Tricks for Working with SAP

This second transaction type displays a list of related objects. The relationship between the objects is defined by selection criteria, which you enter on the initial screens of those transactions. These selection criteria consist of one or more specific data entries (either codes or text) for one or more datatypes for that object.

For example, the SAP record for work orders contains hundreds of bits of data of all types, such as the equipment being installed or maintained; the physical plant responsible for the work; the status and nature of the work; and the dates when it was done. Consequently, the initial screen for a list display of related work orders contains data entry fields and selection boxes for all these possible selection criteria (Figure C.4).

The simplest way to use this sort of screen is to state your objective for this transaction, find the data entry fields and selection boxes that correspond to that objective, and enter your selection criteria there. Here are three real life examples.

• You are the manager of a physical plant, and you want to know how many work orders are awaiting action by your work crew (described by SAP as outstanding in status) or being done by them (or in process in status).

  To set up this transaction for this purpose, you would select the Outstanding and In-process order statuses (A) and enter your plant code in the Planning Plant field (B).

• You are a quality control manager, and you have heard from a plant manager that transformer X (which is installed at seven sites in their district) requires much more maintenance work than transformer Y (which is installed at five sites). You want to research the maintenance histories of these 12 devices.

  To set up this transaction, you would select all the available order statuses (A) and enter the codes for the 12 devices on the multiple selection screen for the Equipment field (C).

• You are the vice-president in charge of all the physical plants in your company, and you are planning the budget for next year. You want to create a list of all work orders conducted last year by these plants.

  To set up this transaction, you would select the Completed order status (A), enter the codes for all the plants on the multiple selection screen of the Planning Plant field (B), and enter the dates for the past year in the Period field (D).

The initial screens of list-display transactions are especially amenable to the application of screen variants (see Lesson 13). You can use this technique to hide those data fields that you never use and to prepopulate fields with codes that you always enter when you run this transaction.

Once you set up the initial screen for this transaction type, you execute it by clicking the Execute button (E) in its application toolbar.

The output screens for this transaction type display their data in the form of line-item reports (Figure C.5). Each line displays by default a few columns of data on a single object that matches all your selection criteria. You can display the database record of one of these objects by double-clicking its code. For this example, this action would call up the Central Header screen for a work order (Figure C.3), on which all its data are displayed.

The default versions of these line-item reports do not usually show much useful data, because the developers who set it up could not anticipate the varied needs of its many users. However, the reports can be customized with filters, sorts, sums, and display variants (see Part IV), so that they display data that are relevant to the problem at hand.

For example, the vice-president in our third example could create a display variant that

• Displays the plant code for each order, and groups the line items by this code;

• Displays the actual costs for each work order, and subtotals this value for each plant.
