Cross Ledger Allocations- Unable to generate

Summary:

Unable to generate Cross Ledger Allocations

Content (required):

This is the business scenario:

CA Ledger

Account Combination(example- there are a larger number of portfolios)

210(LE).410100.(A/C). 1234(Portfolio).......100

210(LE).410100.(A/C). 2345(Portfolio).. ...200

210(LE).410100.(A/C). 5678(Portfolio)......300

This needs to be moved to

US Ledger

Account Combination(example)

110(LE).410100.(A/C). 1234(Portfolio).......100

110(LE).410100.(A/C). 2345(Portfolio).. ...200

110(LE).410100.(A/C). 5678(Portfolio)......300

However, while defining the allocation rules, I am getting the following message:

FUN_ALLOC_MANY_DR_CR The allocation has created multiple debit and multiple credit lines because of which the provider line can't be determined.

While reading a number of notes, I am not sure if the above is achievable. I was thinking this was an easy scenario!
