RWT-2017-00-E PICTURE missing

You did not follow the keyword designating a PICture or IS in a SUM/SOURCE/VALUE statement with a COBOL picture character.
Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Resolution:

Remove the PICture clause or supply a correct picture following the keyword. Note that AMB does not require a PICture clause, but having one helps catch incompatibilities between the mock-up and the SUM/SOURCE/VALUE statements early in the debugging process (at compile time, rather than execution time).
