Hi,
The system will apply costs and prices in this order :
1- "Prices & Discounts" from the Job card.
2- Resource Card
I'm not sure about "Job Planning Lines"!
About this question:
When posting the Job Journal for an approved Time Sheet, why is the Unit Cost and Unit Price not pulled from Job Planning Lines?
Check that you have the correct values in the time sheet (Job No. / Task No. / Work Type). In not, reject the time sheet, reopen it and set the correct infos. Also, make sure that "Chargeable" if true in the time sheet line.
