Suppliers Entity Custom Report

Good Day,
I have Managed to Add suppliers to my Entity List , so when i do a purchase , i can choose suppliers.
it works fine, but there is no where under report or account that i can see those suppliers.

so now how can i call inventory purchase transaction details and call ENTITY ?
i tried
{ REPORT ENTITY DETAILS: Entity Details}
{ REPORT INVENTORY TRANSACTION DETAILS: Entity Details}

still no luck, i don’t quit understand how to call an entity i made ina report.

Try this:

[Purchases by Supplier:1, 1,1,1]
{REPORT INVENTORY TRANSACTION DETAILS:T.AccountName
,T.ItemGroup
,T.Quantity
,T.TotalPrice.Sum
,}

Total|{REPORT INVENTORY TRANSACTION DETAILS:T.TotalPrice.Sum}
[Purchases:2, 1,1, 1]
{REPORT INVENTORY TRANSACTION DETAILS:T.Name
,T.Quantity.Sum
,T.Unit
,[T.TotalPrice.Sum]/[T.Quantity.Sum]}
