Hi Sharanya,

Describe table < internal table name > lines n.

In R/3 this statement will give the number of table rows of the internal table .n should be of data type i.

Eg : If the internal table has 3 records n will have the value of 3.

If you are using a RFC you can store n in an export parameter

and can retreive when it is needed.

hai charu,

Thanks for the response.I have closed the issue as soon as i opened.

In front end i need to refer it as follows

for(int i=0;i<table_ref.getNumRows();i++)

{

wdComponentAPI.getMessageManager().reportSuccess(""+table_ref.getValue("VOLTAGE"));

table_ref.nextRow();

}

Thanks n Regards
