Do you want to add links to your web-enabled reports?

1 Introduction

WEBRFC allows you to publish your standard SAP reports to the web.

Information on HTML templates are stored in table WWWDATA with more
detail in WWWPARAMS (background colors, file extensions). See the CAALR.HLP file for details on WEBRFC programming.

Webrfc provides additional functionality to your standard reports:
- Create links in your standard reports to:
-- other reports
-- external web pages
-Dynamically change templates by using placeholders

1.1 Requirements

For a SAP report to be published to the web you need to have completed the
following:

· Given the program an authorization code. The ITS user that runs the reports will need access to this group

· The report needs to have been released for internet use on each applicable client. (SMWO)

NOTE: The current WEBRFC setup has a small issue when logging on. If you make users log into the WEBRFC and they happen to make a mistake with their login details, SAP keeps this first attempt for all future attempts to run WEBRFC reports, thus leading to the user never getting into a WEBRFC report until he closes his browser and reopens another one and correctly enters his details!!!

1.2 Tweaking your reports
1.2.1 Adding URLs in your reports

To link a URL to a specific part of a line in the list generated by an ABAP report program, use function module WWW_SET_URL in the program. Take the following steps:

1. Generate the list line with the WRITE statement.
2. Call WWW_SET_URL directly after the WRITE statement.
3. Specify the offset of the desired link in the OFFSET import parameter.
4. Specify the length of the desired link in the LENGTH import parameter.
5. Specify the URL you want to link to as a literal or as a variable in the FUNC import parameter.
6. Pass an empty internal table with structure W3QUERY to the tables parameter QUERY_STRING.

When you execute the program in the R/3 System, the resulting list has the same appearance as it always does. However, when you execute the program from a Web page, the specified part of the list line is presented as a link. If you click on this link, you access the URL address.
