Data Management (DMS) allows DMS administrators to manage system configurations. If you are a DMS administrator, you can modify the system configuration items to flexibly meet your business requirements. This topic describes how to modify the system configuration items.

Prerequisites

You are a DMS administrator. For more information about how to view the role of a user, see View owned system roles.

Procedure

  1. Log on to the DMS console V5.0.
  2. On the Configuration Management page, find the configuration item that you want to modify and click Change in the Actions column.
    Note For more information about configuration items, see the Configuration items section.
  3. In the Change Parameter Configuration dialog box, change the value as needed.
  4. Click Confirm Change.

Configuration items

Appendix: Reasons for data changes

DMS provides the following default reasons for data changes, in the format of JSON strings: 

[{"key":"config_correct","value":"Modify Config"},
{"key":"project_init_data","value":"Init Project Data"},
{"key":"program_bug","value":"Program Bug"},
{"key":"require_deal_without_backend_function","value":"Requirements Without Backend Function"},
{"key":"history_data_clear","value":"History Data Clean"},
{"key":"test","value":"Test"},
{"key":"mis_operation","value":"Mis Operation"},
{"key":"others","value":"Others"}]

The following table describes the default reasons for data changes.
