IDOC_AAE Sender Adapter in SAP PO

Overview:

• A business scenario in which IDoc is to be sent from SAP-ECC to Non-SAP System via SAP-PO (SAP Process Orchestration 7.5 Single Stack).
• Here, in this blog, we focus on how IDoc is been transferred from SAP-ECC to SAP-PO.
• In SAP-PO, IDoc-xml is to be transformed to a specific message format of Non-SAP System using Graphical Map and transformed message will be sent to Non-SAP System using SOAP Receiver Adapter communication channel, thus technically it can be called as a “Outbound IDoc-to-Soap Asynchronous Interface”.

Communication Channel Configuration:

IDoc is been transferred from SAP-ECC to SAP-PO using IDOC_AAE Sender Adapter, which can be configured in following manner:

1. RFC Server Parameters: Default(Recommended)

2. RFC Server Parameters: Manual

3. RFC Server Parameters: From NWA

Common errors during IDoc processing:

Normally in SAP-ECC’s t-code SM58, we see following common errors during outbound IDoc processing:

[1] Bean IDOC_INBOUND_ASYNCHRONOUS not found

[2] Error when opening an RFC connection (CPIC-CALL:

[3] Commit fault: ASJ.ejb.005043 (Failed in component: sap.com/com.sap.aii.ad

Resolution of above common errors:

• 3rd Error can be resolved by correcting/verifying following points:
  1. Check IDoc_AAE Sender channels started or not
  2. Also verify SAP-ECC’s t-code WE20 partner profile outbound parameter details
• 1st and 2nd errors can be resolved by correcting NWA Configirations for ‘Default’ settings as given below…..

NWA Configuration Steps for ‘Default’:

 [1]         In SAP-PO create a RFC Destination connecting to SAP-ECC

Create one RFC Destination named as  ‘XI_IDOC_DEFAULT_DESTINATION’

NWA url:       http://sappoHost:port/nwa

Path:             NWA -> Configuration -> Infrastructure -> Destinations -> Destinations

Enter SAP-ECC details like:

• Target Host                    eccHost
• System Number             eccSysNum
• System ID                      eccSystemID
• SAP Gateway Host        eccHost
• SAP Gateway Service   sapgwXX
  • where XX is SAP-ECC’instance Number (generally value is 00)

[2]          In SAP-PO, Resource Adapter ‘inboundRA’ configuration

Path: NWA -> Configuration -> Infrastructure -> Application Resources -> filter ‘inboundRA’ -> select ‘inboundRA’ ‘Resource Adapter’ -> Tab ‘Properties’

In ‘Properties’ tab, maintain following settings:

• ProgramID                          PgmID_Ecc_PO
• MaxReaderThreadCount    5
• DestinationName                XI_IDOC_DEFAULT_DESTINATION
• GatewayServer                   eccHost
• GatewayService                  sapgw00
• Local                                   false
• BindingKey                          PI_AAE_IDOC

[3]          In SAP-PO, starting Java Applications for Resource Adapter ‘inboundRA’

Path: NWA -> Operations -> Systems -> Start & Stop -> Java Applications -> filter ‘inboundRA’ -> select ‘com.sap.aii.adapter.idoc.sapjra.inboundRA’ -> start

Once Java-Application ‘com.sap.aii.adapter.idoc.sapjra.inboundRA’ gets started, its status turns to green, and respective ‘inboundRA’ status also turns to green

[4]          In SAP-ECC, check Registered Program

Once Java-Application ‘com.sap.aii.adapter.idoc.sapjra.inboundRA’ gets started, at this event, program-id ‘PgmID_Ecc_PO’ gets registered in SAP-ECC

Registered programs in SAP-ECC can been seen via following steps:

• in t-code ‘SMGW’
• -> Menu item ‘Goto’ -> ‘Logged on Clients’
• 
• Once window opens, check TP Name= program-id ‘PgmID_Ecc_PO’
• Here total 5 entries of TPName ‘PgmID_Ecc_PO’ can be seen, as maxThreadCount in ‘inboundRA’ is given as 5.
• 

 [5]         In SAP-ECC, create a tRFC RFC Destination

Create one tRFC RFC Destination (t-code SM59) with following parameters:

• Registered Server Program        enabled
• Same program-id                        PgmID_Ecc_PO
• GatewayHost                              eccHost
• GatewayService                         sapgw00
• Unicode                                      enabled

Testing:

Once above configuration gets completed, to trigger IDoc from SAP-ECC to SAP-PO, we need to do following tasks:

1. ALE-Configurations for outbound IDoc
   • In SAP-ECC,
     • t-code BD54:  maintain Logical Systems for SAP-ECC, SAP-PO
     • t-code WE21: maintain tRfc PORT having tRFC destaination
     • t-code WE20: maintain Partner profile for outbound IDoc
     • t-code BD64:  maintain distribution model
   • In SAP-PO,
     • use import/use meta structure of IDoc in Enterprise Repository
     • Configure scenario having IDoc_AAE Sender Channel with ‘Deafult(Recommended) settings’
2. Trigger IDoc
