Item cost/accounting are not getting captured by system

Hi All,

Recently we have changed cost method from PWAC to PMAC. After changing the cost method only purchase orders are getting costed all other transactions not getting costed and not getting accounted.

Please provide your valuable inputs.

Steps taken:

1. Created Cost method (PMAC)

2. Assigned cost method(PMAC)  to cost calendar

3. Updated Fiscal Policy's with newly created cost method.

4. Closed Nov-16 periods in PWAC, created a sample transactions in Dec-16 and ran OPM process in PMAC.

5. Observed only purchase order are getting costed and accounting all other transactions are not getting costed and accounted.

Note: tried to copy the item cost form period Nov-16 (PWAC) to 12 (PMAC) and ran actual cost process but still no use.
