Introduction

This white paper explores various methods of accessing ECC/R3 data through Crystal Reports.

Connecting Crystal Reports to ECC

The following is discussed as to how data is extracted from ECC to Crystal Reports.

Function Module

Table and Table joins

InfoSet and Query

Accessing Data through Function Module

There is a Function module z_salesorder_item_getdata that extracts header-level data for a particular document number. This FM data can easily be accessed by Crystal Reports.

Here are some details of the Function Module under consideration:

Import Parameters

Note: Export parameters are blank.

Tables

Exceptions

IF SY-SUBRC <> 0.

RAISE RECORD_NOT_FOUND.

ENDIF.

APPEND LINES OF IT_VBAP TO ET_VBAP.

ENDFUNCTION.

Accessing Function module through Crystal Reports

Here are the steps:

Step 1:

Go to the database expert. Navigate to the Function module.

The Function module is listed in the data source tree (Sap Tables, Cluster or Function).

Step 2:

Copy it to the right hand space as shown in the figure below:

The function module is now ready to be used for the report. The available fields appear inside the Function module in the Field Explorer.

Accessing Data through Standard Tables or Views

Crystal Reports can also access tables or views just like the function modules. Joins can even be created directly in the database expert just by selecting more than one table.

The following example will create a table join between the VBAP and VBAK table

Step 1:

Go to the database expert.

Step 2:

Select the two tables as shown in the figure below:

The join is automatically generated.

Step 3:

Click OK. The table fields are in the field explorer.

Step 4:

Drag and drop the field in the canvas to create the report.

Creating Crystal Report through InfoSet or Query

InfoSet Query is suitable for reporting in all areas of the SAP R/3 system.

How to Create an Infoset

Step 1:

Go to tcode SQ02.

Step 2:

Give a suitable name to the InfoSet. Click Create.

Step 3:

Provide the description and the name of the base table.

Step 4:

Click Insert table on the InfoSet design canvas to select the appropriate table to be joined.

A join is automatically created, but it can be modified.

Step 5:

Provide the field group details.

Step 6:

Click Generate on the InfoSet manage screen.

The infoset is now ready

Remember to assign roles and user groups to the infoset. Otherwise, it will not appear in the Crystal Reports database expert.

After assigning the roles and user group to the infoset (these should also be mapped to the user ID being used), the infoset appears in the database expert.

Since the query area is in global, the test infoset just created appears under the group of G.

G = global

L = local

I = infoset

Q = query

Step 7:

Click Finish. The infoset is ready in the field explorer of the Crystal report. Similarly, access an infoset query.
