AUC Asset Affected in PS?

Hi,

I am taking care of FI-AA module. Our user would like to close the WBS.The WBS was actually fully settled to the other 2 Fixed Assets some yeas ago:

AsstA : AUC with zero value in Book Depre area.

AsstB : Fixed Asset

AsstC : Fixed Asset

The AsstA is having NBV in other Depre area. The WBS cannot be closed as as the AUC AsstA is having the value in other depre area. FI walkaround is to turn off the 'Investment Measure' for the particular asset and re-adjust the value via transaction. My worried is, the value adjusted, would there be any posting/affects to/in the PS system?

Can someone share your expertise? Thank you in advance.
