Profit center not getting updated default by Buss area in ECC

Hi Experts,

We are working on Ecc 6.0 version and using Document splitting. I confugred 2 co.codes and activated same Document split method. Now when i am trying to post Asset invoice through F-90, if i entered Buss area in Asset line item, system automatically picking the Profit center which i need. But this is happening for my first co.code only, not for the second co.code. The configuration is the same. But when i entered the Buss area in Asset line item for second co.code, the Profit center field getting blank and grayed out, where i can't enter manually also. System is not allowing to post the Document without Profit center.

I need profit center should pick automatically through Buss area like first co.code.

I have 2 Controlling ares by co.codewise. The Cost centers are assigned for both asset masters and Profit centers also assigned in the Cost centers. The posting keys & Field status groups are using same for both co.codes.

Please provide me the possible reasons / solutions for this problem..............

Thanking you,
