So I find out that the following statement in my esql does not work.

Quote:

InputRoot.MRM.TranType = 'IUpdate';

so I traced it and found this in the log

Quote:

UserTrace BIP2538I: Node 'InventoryUpdate.UPDATE_INVENTORY.Update Inventory DB': Evaluating expression 'InputRoot.MRM.TranType = 'IUpdate'' at (InventoryUpdate.UPDATE_INVENTORY_Compute.Main, 12.35).
2004-09-16 16:42:49.448337 6076 UserTrace BIP2538I: Node 'InventoryUpdate.UPDATE_INVENTORY.Update Inventory DB': Evaluating expression 'InputRoot.MRM.TranType' at (InventoryUpdate.UPDATE_INVENTORY_Compute.Main, 12.6).
2004-09-16 16:42:49.480754 6076 UserTrace BIP2543E: Node 'InventoryUpdate.UPDATE_INVENTORY.Update Inventory DB': (InventoryUpdate.UPDATE_INVENTORY_Compute.Main, 12.20) : Failed to navigate to path element because it does not exist.

then I inserted a trace node and saw that TranType was getting set this is what the messgae looks like

(0x0300000B)http://www.restq.com/XMLSchema/BIM:Password = 'qb:Password'
)

(0x0300000B)http://www.restq.com/XMLSchema:AvailableQty = 20
)
)
)

any ideas why the esql cannot navigate to TranType? Am I referencing it correctly? Oh and I did import the schema from an xsd into a message set and the schema has namespaces. That should not matter right?

The namespaces is exactly the problem. ESQL can't navigate to the field because you aren't referencing it correctly, because of the namespace.

You need to declare a namespace

Code:

declare abc namespace "http://www.restq.com/XMLSchema/";

and then reference InputRoot.MRM.abc:TranType, and all the rest of your fields in the same manner.

Thank you! That was it. I had to use the namespace.
