Adjust Cost - Item Entries - Blocking issue

Techcronus

Hi All,

My client is having Dynamics NAV 2013. The issue we have is, anytime we do a Cost Rollup (Bulk update of Item cost of raw materials) the "Adjust Cost - Item Entries" process/report ends up taking 30+ hours. Normally it takes only a few minutes each night. This process ends up blocking everyone for almost two day from posting anything, including production, which is a 24/7 operation.

We are using Standard Cost for all Items and Cost adjustments are being done once a month using the Standard Cost Worksheet in NAV.
Does anyone can suggest us the best way to do the cost rollup and run adjust cost report with much faster way? or
Do you guys suggest any modifications in the adjust cost report and underlying codeunits to make the entire process run fast.
