Very helpful thank you Ravi Sankar Venna. I managed to successfully complete an LSMW but in a trial and error way. I really need you help!

Thank you in advance. T hank you for answering. Just start from the step load your file. Document is very helpful for being a Functional consultant because I have upload number of Master data in my current project without any coding. How can I view the records I have uploaded? I am a newbie in SAP. This manual served me to upload costcenters massively and it worked! Unfortunately you made the mistake that was only discovered in the last step already in the first step.

Personal defaults like view selection is no recorded, as a usual scenario would be that a developer creates the recording BDC and a user executes it, and it cannot be stepd that any user has the same personal ls,w. Further is a recording for a full blown material master in most cases insufficient as different material types have different views, and fields in the view depend on other lamw values.
