We have implemented BCS (Budgetary Control System) in 2009 and prior to that we were using Funds Management (now termed as Former budgeting). We have created some Purchase requisition in FY 2005-2006-2007 in those fund center & commitment item which were not mark as budgetable & posting in Budget structure FM9K. (Year of budget structure is 2003)
Now today when we try to de-release such PR system requires to maintain the Budget structure accordingly.
My query is
Changes in Budget Structure now in FM9K (after implementing BCS) had any data inconsistency issue or not. If yes what would i need to ensure before making change in budget structure (of FY 2003)
Even if i change the budget structure system is giving error message that FM posting period is not open. I had checked FMIR and the interval is maintained from 2008 onwards. I need to make fresh entries for FY 2005-2006-2007.
If i make changes for new entries of FY in FMIR does it lead to any data inconsistency or not, else is there any another way out.
Please resolve my query
