Function Module for string
I want to uplaod data from excel .I want to put validation that If the name1 already exists in database table LFA1, then that particular record in which that name exists will be fetched in one error internal table.
I want to match full name,irrespective of case.
Suppose We are again uploading Ran Avtar or ram avtar, this record get appended in error internal table
Is any function module exists for this.
or suggest me some other solution.
