Flow

Flow is a specialized modification of http_proxy Backend Connections and is used to establish connections to process engines (IGUASU and INUBIT). You can find detailed documentation on the IGUASU connection here.

The various configuration options for Flow are presented and described below.

Create new Flow component

Add a new component in the Flow tab.

The type of Flow is selected using the "Type" input field. Depending on the type selected, the specific configuration options are displayed.

Settings

Setting (Key) Group Type Description

Setting (Key)	Group	Type	Description
ModuleHeader (`moduleHeader_enabled`)	Module	bool	Enables the ModuleHeader to be activated/deactivated
Module_Description (`moduleHeader_description`)	Module	text	Enables a short description of the module to be stored. Can be displayed in the ModuleHeader, for example.
Module_Icon (`module_iconCls`)	Module	text	Displayed FontAwesome icon of the Backend Connection instance.
Module_Name (`module_name`)	Module	text	Name of the module
Connection_Password (`connectionPassword`)	Module	text	Password for authentication of the Connection (BasicAuth on the target server)
Connection_Username (`connectionUsername`)	Connection	text	Username for authentication of the Connection
Connection_Timeout (`connectionTimeout`)	Connection	number	Maximum timeout of the Connection. Default: 180
Connection_CheckCsrfToken (`checkCsrfToken`)	Security	bool	Enables the deactivation/activation of the CSRF token check.
Connection_SendSessionId (`sendSessionId`)	Security	bool	If active, a session ID (in the header "X-SessionId") is also sent, which can be used to query the user and their roles and rights, but without being able to make API calls in their identity. Default: false
Connection_InjectUserSessionJWT (`injectSessionJwt`)	Security	bool	The OIDC ID token is set in the header ("X-Bpc-Session"), which contains the user information. Default: false
Connection_UntrustedCertificates (`allowUntrustedConnections`)	Security	text	All certificates are trusted and the Common Name (CN) check is skipped. Default: false
Http_Header_Filter (`httpHeaderFilter`)	Proxy	json	List of header names that are to be filtered out. For security reasons, the BPC API key header (`X-APIKey`) is always filtered. Default: `[ "X-Frame-Options" ]`
ProxyServer_Port (`proxyServerPort`)	Proxy	number	The Port under which the proxy server can be reached. Default: 80
ProxyServer_URL (`proxyServer`)	Proxy	text	The address of the proxy server to be used. Remains empty if a direct connection to the target server is possible.
Service URL (`connectionBaseUrl`)	Target	text	This parameter defines the base URL to the target system and is prefixed each time it is used if no frontend URL is defined.
FrontendURL (`frontendUrl`)	Target	text	If the flow frontend can be reached under a different URL, this can be configured here. This is relevant for jumps from the BPC to the flow.

Default: 80

ProxyServer_URL

text

The address of the proxy server to be used. Remains empty if a direct connection to the target server is possible.

FrontendURL
(frontendUrl)

Target

text

If the flow frontend can be reached under a different URL, this can be configured here. This is relevant for jumps from the BPC to the flow.

IGUASU specific settings

Setting (Key) Group Type Description

Setting (Key)	Group	Type	Description
System ID (`systemId`)	Target	text	The system ID is configured in the IGUASU HybridRESTClientController Service and is only relevant if the BPC receives messages from different IGUASU instances.

System ID
(systemId)

Target

text

The system ID is configured in the IGUASU HybridRESTClientController Service and is only relevant if the BPC receives messages from different IGUASU instances.

Flow Manager

The Flow Manager contains the most important basic settings of a flow component for quick and clear configuration. It contains the additional "Processors" area, in which the processors with which the BPC can communicate in order to start a flow are listed in a table. This table contains information about the ID, name and description of the processors that have been configured in the respective process engine (IGUASU or INUBIT). You can jump directly to the processor via the jump column.

The jump only works if an external URL has been set as a Service or Frontend URL. If an internal URL is used as a Service URL because both are in the same system, a Frontend URL must be set. If they are not in the same system and Service URL is an external URL, Frontend URL does not have to be set additionally.

Flow in Process Monitoring

If a user wants to jump to the IGUASU from a monitor, a flow component must be set up. This makes it possible to navigate directly to the respective process or Service in the IGUASU via a defined link. For this jump to work, the monitor view must contain a column that provides the corresponding link. This is done via the column externalReference, which is configured with a so-called flowId. The flowId is the ID of the flow component and can be defined when the component is created.
Prerequisite: A flow component must have been created beforehand. The flowId of this component must then be stored in the column configuration (Monitor_ColumnConfig).
Detailed information can be found at Jump from BPC to IGUASU.

The following application option is still under development. The next section is for completeness and the warning will be removed when the feature is released.

In the Monitor settings various endpoints can be configured, for example to Process actions, Status change or Downloads can be carried out. In this case, processors can also be selected directly from Flow instead of endpoints.
