In the Inventory Setup window, if you place a check mark in the Expected Cost Posting to G/L field, you can post expected cost in order to get an estimate of the cost of the received items before receiving the actual invoice.
If you place a check mark in this field, and there are already expected cost value postings, the program posts these expected-cost value entries to the general ledger the next time you run the Post Inventory Cost to G/L batch job.
Expected costs are posted to interim accounts in the general ledger. If you want to post expected costs, you must set up interim accounts for the relevant posting groups.
Enabling any of the following: expected cost posting to G/L, automatic cost posting, or automatic cost adjustment means that the amount of entries the system creates and the level of detail produced every time you post something will increase. This may reduce the performance of your database considerably.
