IMSPE - Environment Parameters for Natural IMS TM Interface

This Natural profile parameter can only be specified with the NTIMSPE macro, dynamic parameter specification is not possible yet.

The NTIMSPE macro is used to define environment-specific parameter sets, which can be assigned to transaction definitions (ENVPID keyword subparameter of NTIMSPT macro).

Note:
You can only define an NTIMSPE macro to the Natural parameter module if the module already contains at least one NTIMSPT macro. Otherwise, an assembly error occurs when trying to assemble the module.

Possible settings	See below.
Default setting	See below.
Dynamic specification	no
Specification within session	no
