Sage 100

Has anyone seen this type of error before? Error Encounterred Invalid Argument program SO_CommonEntryDetail.pvc. Today it happened while in SO invoice data entry, hitting yes to ship all item on sales order. The error points to file SO_lastpurchasehistory.M4t. If I try and make a copy of this file under MAS90 directory, I receive an error Invalid MS-DOS function, try again, skip or cancel. I tried copying their MAS_XXX company and I received the same thing on more than one file. This happened to them about two months ago and we had to restore from backup and they replaced a damaged hard drive but can it be the same thing again?! She reported an issue yesterday running an inventory sales history report, same type of error Invalid argument and IM_itemcustomerhistorybyperiod.m4t file gave me same Invalid MS-DOS so we replaced from backup. All seemed fine until today. MAS200 Version 4.40 SU6 -FYI, when I reported two months ago, Sage didn't help. Any feedback would be appreciated

Sage 100 version ?? Program error line ??

To verify the file is corrupted, you can try to open the file is Data File Display and Maintenance. If it is corrupted, you can only restore the file from backup. I assume the file is not busy or locked.

@Kenneth: the files can be opened from DFDM but it seems like MAS cannot read it when being used in a task or report and we cannot make a copy of it. @ Lee: Version is 4.40 SU6 the error shows the following: Invalid argument Program so_commonentrydetail.pvc line 1870, no error number.

Possible Resolution: Reset the grids: Right-click anywhere on the Sales Order Invoice Entry window. Point to Panel Settings, and click Reset Panel. Select the Reset All Grids check box, and click OK. .... invalid argument error might be a modified screen pointing to a non-existent field.
