Hi Nagarajan,
Thank you for the reply. I am afraid that we somehow had lost the "s" code to access to those Notes (after the company implemented B1 in 2003 or 2005)...
What we are doing right now is to setup labour and travelling costs as non-inventory items, then adjust the numbers in the sales order after we get the actual cost information, which is based on the invoices from sub-contractors. I am not sure if the Note suggested some similar work-around? If yes, then most likely someone in the company had gone through the Note and helped that setup in the past. We also utilize the Service module to record those services and link documents from both Sales and Purchasing sides.
It becomes more challenging with such setup when we get busier - it will take the end users some time to manipulate among different documents to make sure the numbers are correct. If something gets wrong, it will take more time for accounting to adjust, in other words, this increases our operation costs.
Let me try to figure out what the Note suggests, but thank you very much for the information.
Jimmy
