APK275S DATA IN A FORMDEF RESOURCE IS INVALID: A MEDIUM MAP SPECIFIES ONLY CONSTANT DATA FOR A PAGE.

Explanation An
attempt was made to process a page using a medium
map specifying Constant Forms Control for both the front and back
sides of a duplexed page or for the front side of a simplexed page.
Another medium map must be invoked to allow processing of the remaining
line or page data. The Constant Forms Control is contained in a Medium
Modification Control (MMC) structured field.
The MMC structured field is
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 error and resubmit the print request. Refer to Data Stream and Object Architectures Mixed Object Document
Content Architecture Reference for more information about the structured field.  If the structured field has no error, 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.
