This becomes more complex as expected - I increased VTP to 30 000! And it is still not enough! This time error pointed to TBAMT(30000).

Note that this activity code VTL needs to keep compliance with VTP one and also with MAXVANA parameter value.

VTL = number of analytical distribution by account line

VTP = number of analytical distribution by account entry

MAXVANA (TC>CPT>MAXVANA) = max number of analytical distributions You need to keep the proportions below:

MAXVANA = VTL

VTP = 3 x VTL

Example:

If you upgrade VTL to 500, you have also to upgrade MAXVANA to 500, and VTP to 1500. Then you have to run a dictionary validation (VALDICO) for each activity code (VTP and VTL) to apply the new value on all X3 elements.

I did as you suggested. Currently, I think, that I  max values VTP=30 000, VTL=10 000 MAXVANA=10 000.
Is it possible to split somehow in more entries rather have in few?

Those numbers do not help. 

I modified field ACCVRC (one journal per account) - started year closing function. Right now it is running already 20 hours!!!
Is it possible to close the year manually? Because a variety of accounts/dimensions are not so high. 

Hello,

How many Ledgers are you using? A possible resolution I've seen for this issue is to Uncheck the "Closing Document" Checkbox on the actual Ledger(s) that you're using and retry the Fiscal year end close. 

Setup>Organizational Structure>Ledger

Thanks,

This one helped - thank you!

This one helped - thank you!

This year I come to this problem again - now suggested solution does not help. Maybe some other bright idea?
