APK181S DATA IN A FORMDEF RESOURCE IS INVALID: UNEQUAL COPY COUNTS FOR DUPLEX SHEETS ARE SPECIFIED IN THE MCC STRUCTURED FIELD.

Explanation The set of modifications referred to by
the Medium
Copy Count (MCC) structured field includes
duplexing, but the numbers of copies in two corresponding repeating
groups are not equal. The repeating groups are defined in the Medium
Map Control structured field (MMC).
The MCC and MMC structured fields are
contained in the form definition. 

System action ACIF
stops processing the print data set and issues
a message identifying the position of the structured field in the data stream or
resource.

System programmer response If an IBM® licensed
program was used to create the structured fields for the form definition
with the error, verify that the input to that program was valid. If
the input was valid, refer to your system's diagnosis reference for
assistance in determining the source of the problem. 

User response
 If you created the structured fields for the form definition,
correct the MCC or MMC structured field.
Refer to Data Stream and Object Architectures
Mixed Object Document Content Architecture Reference for more
information about the structured field.
If the MCC and MMC have no errors, the error might be an ACIF logic
error. If you used a program to create the structured fields for the form definition,
contact your system programmer.
