      you published a document.

      The purpose of a document is to explain.

      you just mentioned the goal and posted some unexplained coding lines

      so it is a bit cumbersome why you are selecting from table LFB1 company code data if you want check a redundand name.

      From my point of view it is to late to check for redundand names when you create company code data views, this should already happen when the address data is maintained.

      Further you get only an error if the name matches 100%, a space more, a different entered abbreviation, a dot to less and you get no hit at all.
