Explanation
  library
ddname of the sequential library
enttype1
already assigned data element type
entname1
already assigned data element name
enttype2
data element type
entname2
data element name
sysmod
name of SYSMOD supplying the data element

 The data element being APPLIED, ACCEPTED, or
RESTORED has the specified library, which is a sequential  data set.
Only one element can exist in a sequential  data set, and there is
already one assigned to it.

System action
 Processing fails for the SYSMODs containing the
data elements.

Programmer response
 Check the DDDEF entry or DD statement for
the specified library to ensure that it specifies the correct data
set. If the data set is correct, verify that the data set was allocated
with the correct organization. If it should have a partitioned organization,
change the allocation and rerun the command.
 If the data set
should be sequential, verify that the DDNAME for the specified data
element is correct. If it is incorrect, correct the SYSLIB or DISTLIB
subentry, and rerun the command.
