Register in the data table 1200. Then, the process shown in this figure is terminated.

  On the other hand, when an instruction for canceling registration of the item-to-item violation setting is received (YES in step S611), the CPU 201 of the information processing apparatus 100 ends the processing shown in this figure without registering the item-to-item violation setting data.

  If the CPU 201 of the information processing apparatus 100 determines in step S601 that the inter-item violation setting addition instruction has not been accepted (NO), the process proceeds to step S612, and the inter-item violation setting deletion instruction has been accepted. Determine.

  If it is determined in the determination process in step S612 that the deletion instruction has been accepted (YES), the CPU 201 of the information processing apparatus 100 proceeds to step S613, and acquires specification information of the item-to-item violation setting for which the deletion instruction has been accepted. Then, the item-to-item violation setting data indicated by the acquired item-to-item violation setting designation information is deleted from the item-to-item violation setting data table 1200 of FIG. 12 (step S614). Then, the process shown in this figure is terminated.

  If the CPU 201 of the information processing apparatus 100 determines NO in the determination process of step S612, the process proceeds to step S615, performs the process according to the received operation instruction, and ends the process illustrated in FIG. .

  The above is an example of detailed processing of the item-to-item violation setting editing processing in step S406 of FIG.

  Here, an example of the data configuration of the inter-item violation setting data table 1200 that is updated by performing the inter-item violation setting editing process of FIG. 6 will be described with reference to FIG.

  As shown in FIG. 12, the inter-item violation setting data table 1200 includes data items such as ID 1201, environment setting file 1 1202, item 1 1203, value 1 1204, environment setting file 2 1205, item 2 1206, value 2 1207, and the like. It is prepared for.

  The ID 1201 is a data item in which identification information for uniquely identifying each item violation setting data registered in the item violation setting data table 1200 is registered.

The A value 1 1204 is a data item in which a condition of a value set in the item specified by the environment setting file 1 1202 and the item 1 1203 is registered.

  In the environment setting file 2 1205 and the item 2 1206, information indicating which item (registered in the item 2) in which environment setting file (registered in the environment setting file 2) is registered. The A value 2 1207 is a data item in which a condition of a value set in the item specified by the environment setting file 2 1205 and the item 1 1206 is registered.

  The item-to-item violation setting data registered in the item-to-item violation setting data table 1200 is the value 2 of the item 2 in the environment setting file 2 when the value of the item 1 in the environment setting file 1 is 1. This means that it cannot be set to (or vice versa).

  The above is an example of the data structure of the inter-item violation setting data table 1200.

  Returning to the description of FIG. If the CPU 201 of the information processing apparatus 100 determines that the operation instruction received in step S402 is not an instruction for editing the item violation setting (NO in step S405), the process proceeds to step S407, and is accepted in step S402. It is determined whether the operated instruction is an instruction for editing the automatic change condition. If it is determined YES in this determination process, the CPU 201 of the information processing apparatus 100 proceeds with the process to step S408, and performs an automatic change condition editing process.
