Document Splitting Issue

Hi Experts!

Im facing problem in document splitting, please have a look at following scenario:

811101 Expense GL1 DR 10000 (Profit Center 10101)

811102 Expense GL2 DR 15000 (Profit Center 10201)

622001 Balance Sheet A/C1 CR 20000

622002 Balance Sheet A/C2 CR 50000

Standard Splitting Method does not cater above scenario as no base item category could be identified for GL 622001 & 622002. & Inheritance will also not work because it is not unique.

Please guide how to cater above problem.

Best Regards
