Map Multiple Account groups of type Classification - Customer from CRM to the same account groups in ECC

Hi ALl,

My requirement isas below:

I have two Account groups in CRM -> Both of type Sold - TO- Party. But with two different number ranges.

I need to replicate them into ECC in the same number ranges as in CRM.

for this i checked the ECC PIDE Settings. I could not maintain Two entries of type CLasisfication 'B' in CRM - R/3 .

I have seen two blogs :

So probably you can implement the logic on CRM side to set this field automatically according, for example, to BP roles assigned to current BP.

Alternatively: you can grab DE_BALE event on ERP side and adjust E1KNA1M segment there. You can find more information on SCN regarding this option."

can u pls be more clear on how do i achieve this..
