Background : Created RFQ (material)-> from sorucing request we created RFP sourcing project-->at award stage we created new contract and completed all contract workspace task and published contract line document and sent to external system.
issue : in CIG wrong document Contract service document is triggering in transaction tracker ( even thoughcontract-cxml.png we have given only material) due to this in SAP SRT_MONI wrong interface "QuoteMessagePurchasingContract_Async_In_V1 is triggered with error " CX_FEH_CONSISTENCY_ERROR:An exception with the type CX_FEH_CONSISTENCY_ERROR was raised, but was not handled locally or declared"
According to Note : https://connectsupport.ariba.com/sites?Recommendation=AC#item-view&/191402
For contract created from quote should have QuoteMessageContract and interface called will be QuoteMsgPurchasingContract_Async_In
In our case Interface is "QuoteMessagePurchasingContract_Async_In_V1" getting triggered for material which is wrong.
