I did costing run for material "A". The result was successful, standard cost is updated in the material master.
Then i did some changes in the routing(given value to the standard value i.e conversion cost) & in kp26(activity type).
When i again running costing, in that marking is showing "X" cross mark. the cost is not updating.
Marking & Release is not happening.
its showing that "of 0 materials, 0 cost estimates were updated succussfully".
Pls give me the solution for this. its very urgent.
