Having an issue with period 0 cumulative balances for random accounts not displaying (null field) in FAGLB03 for fiscal year 2011. When double-clicking on the cumulative balance to get the line item detail, the amount is correct (for example, cumulative balance is null while line item detail shows the correct amount of $1,000). This is only occurring for two accounts each with a different company; these same accounts for other companies are populating the period 0 cumulative balance correctly. We have recently made system copies in our test environment, and the period 0 balances are populated correctly; we also know that as of week ago these period 0 balances were correct in production. Within the past week, for year end closing, tcode FAGLGVTR was processed for 2012. We originally believed it had something to do with an error in running FAGLGVTR and reprocessed for the two company codes that have null period 0 account balances; however the issue is with 2011 period 0 balances (which is now causing an error with 2012 period 0 balances). Any ideas on what might be causing this issue? Thank you in advance.
