CC.2.5 Create a Unified Procedure Step (N-CREATE)
Prev | CC.2 DIMSE Service Groups | Next

### CC.2.5 Create a Unified Procedure Step (N-CREATE)

This operation allows an SCU to instruct an SCP to create a Unified Procedure Step. This operation shall be invoked by the SCU through the DIMSE N-CREATE Service.

#### CC.2.5.1 Unified Procedure Step Attribute Specification

An Application Entity that claims conformance to the UPS Push SOP Class as an SCU shall provide all Required Attributes as specified in Table CC.2.5-3. Additional Attributes defined by the UPS IOD may be provided as well.

An Application Entity that claims conformance to the UPS Push SOP Class as an SCP shall support all required Attributes as specified in Table CC.2.5-3. Additional Attributes defined by the UPS IOD may be supported as well.

##### CC.2.5.1.1 UPS Final State Requirements

COMPLETED and CANCELED are Final States for a UPS instance. The Attributes and values of the UPS instance must meet certain requirements before it may be placed in either of the Final States.

### Note

A UPS instance is in the SCHEDULED state when created. See Section CC.1.1 for rules governing state transitions.

Attributes shall be valued as indicated by the Final State Codes in the Final State Column of Table CC.2.5-3 before the Procedure Step State (0074,1000) may be set to COMPLETED or CANCELED (i.e., Final State).

Performing systems are encouraged to ensure that the values for all Attributes reasonably reflect what was done and the Final State of the UPS. This may include blanking Attributes that are permitted to be empty and for which no reasonable value can be determined. The UPS contents should make it clear whether the step was completed, what work was done, what results were produced and whether the results are usable. See Section GGG.3.1 “What Was Scheduled Vs. What Was Performed” in PS3.17 for a discussion of methods to convey things like partial completion.

### Note

The SCU may choose not to distribute, or otherwise make available, some or all instances created during the procedure step and referenced in the Output Information Sequence (0040,4033).

Table CC.2.5-1. Final State Codes

Final State Code | Meaning
--- | ---
R | The UPS State shall not be set to COMPLETED or CANCELED if this Attribute does not have a value.
RC | The UPS State shall not be set to COMPLETED or CANCELED if the condition is met and this Attribute does not have a value.
P | The UPS State shall not be set to COMPLETED if this Attribute does not have a value, but may be set to CANCELED.
X | The UPS State shall not be set to CANCELED if this Attribute does not have a value, but may be set to COMPLETED.
O | The UPS State may be set to either COMPLETED or CANCELED if this Attribute does not have a value.

##### CC.2.5.1.2 UPS Macros

To reduce the size and complexity of Table CC.2.5-3, a macro notation is used.

For example, in Table CC.2.5-3, a table entry specifying "Include Table CC.2.5-2a “UPS Code Sequence Macro”" should be interpreted as including the following table of text as a substitution. The nesting level for the sequence inclusion is indicated by the nesting level on the reference to the macro. Where the matching key type requirement is "*" it should be replaced with the matching key type requirement of the sequence Attribute that incorporates this macro.

For code sequences that have requirements for N-CREATE, N-SET, N-GET, or C-FIND behavior that differ from the Macro, the code sequence contents are explicitly listed in the Table rather than specifying inclusion of the Macro.

###### CC.2.5.1.3.1 UPS SOP Class UID

The SOP Class UID shall be set to 1.2.840.10008.5.1.4.34.6.1 by SCP

###### CC.2.5.1.3.2 Unified Procedure Step Performed Procedure Sequence

The Attributes of the UPS Performed Procedure Sequence shall only be retrieved with Sequence Matching.

### Note

Since this Attribute may be created empty and has a Final State requirement of X, a UPS in the SCHEDULED state may be canceled with two N-ACTIONS (IN PROGRESS then CANCELED) and no N-SETs.
