Generic Inquiry Parent Child Relation - acumatica

Question

I have been trying to pull up the data from Contract, ContractDetail, ContractItem and InventoryItem in Generic Inquiry. So, after adding up all 4 tables I created relationship as below.
The relationship between Contract and ContractDetail is fine. And now since ContractDetail uses ContractItemID, I have set the relationship as below. But it throws me error like this.
And, upon looking into the stack trace, I find the generated query looks this:
DECLARE #P0 SmallDateTime(4) SET #P0='9/27/2018 12:00:00 AM' DECLARE #P1 nvarchar(MAX) SET #P1='0' SELECT COUNT(*)
FROM (
[Contract] InnerQuery_Contract
INNER JOIN (
[ContractDetail] InnerQuery_ContractDetail_ContractDetail
INNER JOIN [Contract] InnerQuery_ContractDetail_Contract ON [InnerQuery_ContractDetail_Contract].CompanyID IN (1, 3) AND 32 = SUBSTRING([InnerQuery_ContractDetail_Contract].CompanyMask, 1, 1) & 32 AND [InnerQuery_ContractDetail_Contract].[DeletedDatabaseRecord] = 0 AND [InnerQuery_ContractDetail_ContractDetail].[ContractID] = [InnerQuery_ContractDetail_Contract].[ContractID] AND [InnerQuery_ContractDetail_ContractDetail].[RevID] = [InnerQuery_ContractDetail_Contract].[RevID]
LEFT JOIN
[ContractDetail] InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt
ON [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[ContractID] = [InnerQuery_ContractDetail_ContractDetail].[ContractID] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[LineNbr] = [InnerQuery_ContractDetail_ContractDetail].[LineNbr] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].[RevID] = [InnerQuery_ContractDetail_Contract].[LastActiveRevID] AND [InnerQuery_ContractDetail_ContractDetailExt_ContractDetailExt].CompanyID = 3
) ON [InnerQuery_Contract].[ContractID] = [InnerQuery_ContractDetail_ContractDetail].[ContractID] AND [InnerQuery_ContractItem].[ContractItemID] = [InnerQuery_ContractDetail_ContractDetail].[ContractItemID] AND [InnerQuery_ContractDetail_ContractDetail].CompanyID = 3
INNER JOIN [ContractItem] InnerQuery_ContractItem ON [InnerQuery_ContractItem].CompanyID = 3 AND [InventoryItem].[inventoryID] = [InnerQuery_ContractItem].[RecurringItemID]
)
WHERE [InnerQuery_Contract].CompanyID IN (1, 3) AND 32 = SUBSTRING([InnerQuery_Contract].CompanyMask, 1, 1) & 32 AND [InnerQuery_Contract].[DeletedDatabaseRecord] = 0 AND [InnerQuery_Contract].[UsrLockDate] < #P0 AND (CASE WHEN ([InnerQuery_Contract].[BaseType] = 'T' OR [InnerQuery_Contract].[BaseType] = 'R') THEN CONVERT (BIT, 1) ELSE CONVERT (BIT, 0) END) = #P1 OPTION(OPTIMIZE FOR UNKNOWN)
So, there is problem with Alias name for table in the query. So, how do I fix this issue?
Thank you.

Joins in Acumatica works exactly like in SQL. First build the query in SQL and get the result as to what you need and then try to construct the same in Generic Inquiry.
Apart from than, I do not see any relations between Contracts and Inventory. Please explain what you are trying to get.
Here is the way you should join your tables in Generic Inquiry
