Dynamics NAV - Adjust Costs job takes very long.

Create a routine that runs the adjust cost job for one item at a time. in small groups.
Eventually, once all of the items have had the adjust cost complete relatively recently, the entire job will run faster.

Get all items where "Cost is Adjusted" = False

Write a routine to get the next X items ahead in the list.

------------------------------------

GetEndItemRange(ItmRange : Integer) : Text[50]

Itm3.SETCURRENTKEY("No.");

Itm3.SETRANGE("Cost is Adjusted",FALSE);

Itm3.SETFILTER("No.",'>='+FirstItem);

Ct:= 0;

IF Itm3.FINDFIRST THEN BEGIN

  REPEAT

    Ct:= Ct + 1;

    Itm3.NEXT;

    TheNo := Itm3."No.";

  UNTIL Ct = ItmRange;

  EXIT(TheNo);

END;

Call the Adjust Cost Item Entries with the item number filter begin and end to run it only for that small range

-------------------------------------

 Itm2.SETRANGE("No.",CurrItemNo, EndCurrItemNo);

    InvtAdjmt.SetFilterItem(Itm2);

    InvtAdjmt.MakeMultiLevelAdjmt;

Include a COMMIT at the end of the REPEAT to ensure that batch is written so the whole list doesn't get undone if it runs into an error.
