[Former Member]

Hi Experts,

Hi,

First let me explain the functionality of these three statements.

Append: Inserts a record to an internal table

Modify: Modifies a existitng record in the internal table, if there is no record it will throw error.

Update: Modifies a existing record in the internal table if it finds the record, else it will insert a record.

The runtime error may be due to non existance of the record in the internal table. First decide on the functionality you want and carry on with your coding.

What is the complete syntax that you are using for your MODIFY Statement?

Hi Sri,

Modify statement requires a index i.e. the record no which you want to modify . If you do not provide the index then it will give you dump.

If you want to modify the current record in the loop pass i.e. if you are using the the mdify statement in loop and endloop and want to modify the current record which the loop is accessing then give index addition in modify statement.

For e.g.

Loop at itab into wtab.

modify itab from wtab index sy-tabix.

clear wtab.

endloop.

I hope this will help you.

Hi Sri,

there is a significant difference between the functionality of append and modify.

Append statement insert a record into internal table and also allows the duplicate enteries.

but in case of modify if your program is going into dump there can be two reaosns:

1. The data you want to modify may not be present in the table.

2. The fields you are using in modify statement may not be compatible with that of internal table.

So check the syntex of the modify statement you have given and also the table values.

I hope this will work.

Hi,

Modify statement requires a Index .

At modify the internal table with sy-tabix.

i.e. Modify itab from wtab index sy-tabix.

I hope this will help you.
