Issuing inventory items purchased for a specific task, Cost code.

Hi,

Appreciate help on below scenario.

I have created a Purchase Order specifying the project, task and cost code. Then performed the purchase receipt to the same task and cost code & issued half of the items to the same task as per the requirement. There is a leftover of the purchased items and now I need to issue these items to another task.

System does not allow to issue items to another task . How can I perform this scenario.

Thank you,

Dulanjana
