Lsmw- how could i skip the particular line while executing.

Hi,

I need some suggestions from you side,

In my daily tasks, I need to update the material master and create the material master using lsmw.

Suppose...

Material Codes

A1

A2

A3

A4

-----  up to  150  rows.

I am trying to create the materials, While creating it will check it whether A1 is all ready created or not because this is unique only, Duplicates  will not accept.

At 71th row lsmw found that material code was already created , what i entered is duplicate, then lsmw foreground will show and it will try to show the error material code all ready created.

Here my questions i would like to skip the Present line, and continue the 72nd row on words. How could i skip it.

I know /bend it will stop the entire  transaction , Then again i need to prepare the sheet and upload the file.I need to skip the line and continue the execution Up to end of the sheet line. How could i do.
