I'm not sure if I'm posting in the right area for this question but here goes.

I'm running mobile services. When my field service engineer makes a materials request from the warehouse from his PDA/handheld device. The stock is assigned. however if there is no stock in the warehouse, I get a transaction error.

Error : Transaction aborted for component MaterialLine in business object ServiceOrder (Create) Error occurred in Method 'Create' on component 'MaterialLine' of Object 'tssoc200 ServiceOrder'. Cost price structure of item 16128-4027 not found.

The cost on this item is $0.00 dollars however if there is no stock it creates this error.( yes the cost price reflects this- I suspect it blows this error due to lack of inventory)

Anyhow, I need to intercept the materials request from the Mobile Device. and have the materials request approved internally before it is issued and assigned back to the Field Service Engineer.

any thoughts would be greatly appreciated.
