KP26 Need ability to add second line to a defined Activity Type

Hello -

Wondering if someone can assist .

We have defined the cost ctr, activity type, validity period, fiscal year and dollars per hour in KP26. We would like to apply a percentage distribution to that defined information.

See example below:

Activity type = DOC 1 hr. @ $55 distributed as 70% (distribution key 3 is %) = $38.50

SECOND LINE distributed as 30% (distribution key 3 is %) = 16.50

The copy icon in the Change Activity Type/Price Planning: Overview Screen does not permit a copy. The second line is shaded. Without the second line the distribution is incorrect

Thank you for your assistance.
