Problem:
Error when conducting Picking Sheet Printing
Found in: Multi-Bin v. 2018, Product Update 3 or higher

Workaround:
Downgrade to Product Update 2 of Sage 100 Version 2018
Solution:
Programmers have issue a patch set for 2018 PU3 and higher. Program files should be installed to the appropriate CI/IM/SO program directories of /mas90 accordingly
With the latest Multi-Bin Installers this fix will no longer apply, unless an old installer is being used.
