Acmt.022.001.02 Mapper

Overview

The Acmt.022.001.02 (Acmt.022) Inbound Mapper is used by TCH for sending the Token Advice(IdModAdvc) messages from TCH Real-Time Payment System(RTP) to FTM for Immediate Payments. The default mapper name is Acmt022ToISFMapper.

The details of the mapping specification are included in a separate document. Refer to Detailed acmt.022 mapping specification for more information about obtaining the documentation for the mapping specifications.

The inbound acmt.022 mapper can also be used in conjunction with the Business Application Header mapper. Refer to TCH Business Application Header Mapper for more information.

Inbound Mapper

The CONFIG=entry in Channel parameter is required for inbound mapper. The mapper uses the setting to locate <msgTypeCfg> entry in Value table with child element <Type> containing acmt.022.*. The <msgTypeCfg> contains the configuration parameters for the inbound mapper.

For example, the default Request From CSM channel is configured with a CONFIG=IP_MAP_CFG_REQ_FROM_CSM parameter. When a acmt.022.001.02 message is received , the mapper looks for the <msgTypeCfg> entry in the Value table with the following conditions:

In Value table, the value of Category is IP_MAP_CFG_REQ_FROM_CSM.
In msgTypeCfg entry, the value of Type is acmt.022.*.

The default <msgTypeCfg> for IP_MAP_CFG_REQ_FROM_CSM is as follows.

<msgTypeCfg>
	<class>ACMT022</class>
	<subType>IP_FROM_CSM_TN</subType>
	<extendedCfg>
		<name>MASTER_FLAG</name>
		<value>Y</value>
	</extendedCfg>
	<pt>
		<class>ACMT022</class>
		<subType>IP_FROM_CSM_TN</subType>
	</pt>
	<mapName>Acmt022ToISFMapper</mapName>
	<type>acmt.022.*</type>
</msgTypeCfg>

The inbound mapper uses the configuration parameters of the <msgTypeCfg> entry as follows:

<class> - value for TRANSACTION_V.OBJ_CLASS
<subType> - value for TRANSACTION_V.SUBTYPE and ISFMessage/Header/BusinessConcept
<extendedCfg>.<value> with <name>=MASTER_FLAG - value for MASTER_FLAG (for TRANSACTION_V and TRANSMISSION_V)
<pt>.<class> - value for TRANSMISSION_V.OBJ_CLASS
<pt>.<subType> - value for TRANSMISSION_V.SUBTYPE

Note: When the inbound mapper is used in conjunction with the Business Application Header mapper, the inbound mapper checks the value of AppHdr/CpyDplct in Business Application Header. If the value is 'DUPL', the mapper appends '_RPT' to existing <subType> value to indicate the message is a repeat Message Reject message.

If the <msgTypeCfg> entry cannot be located, the mapper throws an exception with error 'subType not found'.

Table 1 shows the default configuration parameters for the channel using acmt.022 inbound mapper.
