Lsmw for mm01 is not working

Question

Hello experts,
We are extending the material to another plant and storage location etc.
so i want to do in lsmw. but it is not working fine .please help me.
First in the lsmw i selected recording and done the recording for mm01.
in the first screen i entered
material abc,industry sector mech engi, material type wfinis and copy from material abc,then i pressed the
enter and i selected the views Sales: Sales Org. Data 1,Sales: Sales Org. Data 2,
Purchasing and Accounting 1.
then i pressed enter and got the screen to enter plant, valuation type , sales org, cist channel. so i enterd
plant ,sale org and dist channel in the organization levels and copy from fields.
then i pressed enter and in the next screen i entered some required data and pressed enter and in another
screen o entered and etc and finally saved . The recording is
successful .then i completed all the lsmw steps when i run the session it is showing the error
at the screen where we enter the orginational levels like plant, sales org etc.
our flat file is a text file and it is in the same order as in
the lsmw.
I approched one senior consultant and he said we cant do lsmw bcuse
the org level screen will be moving every time.
so please kindly help me what to do to analyse this error.
=>Can we debug the lsmw , if so how.
=>In one moment previously 2 days back when i am doing lsmw i got a
error with return code 13, please tell what actually means and where to see this one.
Thank you so much for the replies.

Shiva,
First of all its not advisable to use the recording method in lsmw for uploading the material master data. It involves lot of views so if something goes wrong very much difficult to identify the error point, at the same time I will advise you to go with bapi or idoc method to do the same.
When comes to you question regarding the debugging of lsmw you can debug it.
From the usermenu tab take the generate conversion program step into u r list of steps
then execute it and go into the program and put a break point then execute the convert data step directly you will get into the debugging mode you do debug the code.
