hi mentors

wat are these ,read & .conv files called which are created while uploding the data using LSMW.?

.read is extension for read data from the source file (presentation or application server).

and .conv is the extension for converted source data into a target data format based on the conversion rules defined.

i.e., source fields are mapped to target fields.

In LSMW there are three steps:

1.) Upload the file from the Source. Which is done in the first tab.

2.) Read File : This would read the data records from the file path you have given. You can see the data read from Tab Show READ Data. From this you can see if the Data has been read successfully.

3.) Conv File : This is for converting the file in the format which you want to Upload. Your File Conversion depends upon the FIELD mapping you are doing in Step 5 of your LSMW, Conversion file is finally transferred to the SAP system via method you use to transfer the data in SAP system.

Hope this will help you to understand the terms.
