Hi Kevin,
I am not sure about the silk praposal but in order to active the non leading ledger in existing Co code. You need to install the migration cockpit. Few points need to consider.
Activation of pallet cam be happened in new year that mean all the postings for previous year is completed and you got the auditor confirmation, only then you can use the migration phase.
What happened is previous year position will not migrate to non leading ledger only current year postings will move to non leading leader and as well as Leading Leadger. Y ou required the down times for the activation.
Other threads I have read in SCN some people consultant mentioned they have activate the non leading Leadger with out SAP Migration Service, when you try to active the companies system usually asked.where this company is productive, just simply say No the you can activate it. But in that case if some thing is went wrong at that time SAP will not support and they will charge more money. You can try in sandbox client or QA client first if every thing is fine then yiu font need to use the Migration Cockpit.
But if you the Migration Cockpit one more thing cone in your bet and try to convince your business to use Migration Cockpit and this will be a separate project.
Use OSS NITES 1227504 for all the questions.
Hope this help reward points.
