Hi,
When you are Planning to create LSMW for any master data, You need to create 1 master data manually and mind that all field which is required is captured correctly.
Second, At the time of Batch in put recording open second screen which you have created manually and give correct data , avoid repeating data field at the time of recording.
Please refer below link -
