Problem with a fusion of two companies

Hi,

Maybe somebody can help me with my problem with implementing FICO modules in two companies which are soon going to become one company. The fusion will probably take place on 1st january, but it can be posponed as well.

Everything is prepared to run the common mont-end closing procedures and common planning/budgeting for both companies from the 1st january.

However, there is a great risk, that the fusion will be delayed.

In that case I suppose it would be better to enter one separate budget for the leading company and upload the budget of the other company after the fusion takes place. These actions have influence on calculating the manufacturing cost of products. It will certainly be different before and after the fusion.

Maybe you can advise me on this subject, wheter I should make a common budget for both companies no matter the date of fusion or make a buget in SAP only for the leading company and upload the budget of the other company after the fusion, and then recalculate the manufacturing cost of products.

Best wishes,
