Cost Center Planning Layout

Hi,

For the combination of the cost center and cost element planning, we are be able to upload one cost center and multiple cost elements. we have 120 cost centers in such a case we need either to upload 120 times or we can use file directory to upload the 120 file one time.

My question: Is there any alternative way to create one planning layout allowing upload multiple cost centers and multiple cost elements in one file?

Regards,

Ibrahim Mohamed
