You create text elements for an ABAP report. These can then be translated.
With the help of the SAP_BW_TEXT tag that you insert into a Web template, you can access the texts as follows:
<SAP_BW_TEXT PROGRAM=’MYREPORT’ KEY=’001’>
You can also use language-dependent headings for Web items. You can specify the headings as parameters either in the object tag of the Web item
<param name=’CAPTION’ value=’SAP_BW_TEXT?PROGRAM=MYREPORT&KEY=001’>
Or fill the heading in the Web Application Designer as follows:
SAP_BW_TEXT?PROGRAM=MYREPORT&KEY=001
