There is an Excel addin that sales man use to create orders for the company. The addin exports to a comma delimited file for pickup by an SAP database based in Oracle.
There are three columns that represent that represent each customer. Every third column starting with I to L to O and so on for 100 columns, and with Rows ranging from 17 up to 2500. Each cell potentially in the I,L, and O columns for those stores, represents a Unit of Measure (UOM) for the product that is ordered in the A column. There is a hidden validation list thart presents a dropdown box for the UOM. The validation list is all Uppercase - otherwise it will not be picked up by the importing SAP.
Salesmen have a habit of entering the UOM in lowercase, and it is accepted by the worksheet regardless of the Uppercase in the Validation sheet.
Is there away to ensure that the cell must be entered in Uppercase, changes to Uppercase on losing focus, or can be something be manipulated with the Validation list itself?
