Hello ​@bldrayi 

Once the inventory transactions are aggregated, inventory statistic periods are closed and you cannot change the date applied since the relevant transaction is calculated in the balance of statistic period of the date applied. The new date applied can be a date from new statistical period.

The only way to correct this is a data repair on relevant tables. I had done this for a client where they mistakenly aggregated transactions before performing year end counting in the system. 

You cannot correct by yourself without a technical support.

Hope this helps

Hello ​@Furkan Zengin 

Why I can’t do a counting if I did an Aggregate?

What processes are affected for this “Aggregate Inventory Transaction per Period”?

Thanks a lot.

Hi ​@TimeMarBou

Say if you aggregate until 31st of January, then you can still post transactions to 31st of January. But if you aggregate until 1st of February then you cannot create a new transaction for January anymore. Because the system validates last aggregation date and block inventory until this date. 

Once you aggregate inventory transactions, ROUNDIFF postings are created (if any rounding is found) and inventory statistic information is updated. They are about 6 table where monthly statistics are recoded.
