12.2.4 Distribution PR allocation percent% by cost center

Dear All

I need solution for this user's operation.

Could you please help me I have only 5 days to find the solutions.

Step

================

1.login to ipo

2.Access to store and shopping item catalog

3.Add to cart

4.update line add distribution account to allocate cost center

5.Add all cost center that is 30 cost center

first cost center I have to allocate 44%

second 9%

and then all 2.35%

but after I create first 10 lines in distribution it must use total 100% and each others next page I have to allocate total to 100%

Why it doesn't support total percent% for all lines distribution?

Why total doesn't summary all of distribution lines and ipo can support only 10 distribution lines?
