I am currently implementing Fixed assets and have a problem with the security on one of the key tables.
Table T090L accesable via transaction AO25 is a table that holds production and reserve values which are input by Fiscal period / year , however the table security is not controlled via the 'posting period vaiant' control (OB52).
The problem I have is that AO25 will allow you to change the values in prior years/periods even though those periods are now closed and the figures have been used in their appropriate calculations.
I wish to be able to restrict periods for user change to avoid prior period adjustments in line with OB52.
Any insight greatly appreciated
