Sage 100

Hi All

  Have a client on 2016 Advanced and they have WOEP..  They have several companies that are very similar in setup.  In one of them when doing PO Period End they get Error Encountered 'IM_ItemWarehouse' does not have correct permissions.   The main part of the info is below:

Error #13: File access mode invalid
Program    SY_SalesTaxCalculation_bus.pvc
Line       2204

General Information:
  File                   IM_ItemWarehouse
  Last Key Value         
  Last Key Text          

  Last Channel Opened    32533
  Last Channel Accessed  0

  Object Number          100077
  Object Method          AddInLine
  Object Text            SY_SalesTaxCalculation_bus

  Available Memory       23266789

I have tried a number of steps.  Of course first I rebuilt IM_ItemWarehouse - no errors found, no issue opening it in DFDM.  As it mentioned Sales tax calculation I rebuilt all the tax files in PO, still no go. I rebuilt every file listed, rebuilt sorts for PO, IM, WO and SO.  All with the same issue.  I ran PE in MAS90 mode.  I talked to Sage and tried renaming the links folder. (their favorite blame game)  Still no change.   I tried purging the PO's before running PE, no change. 

Any thoughts would be appreciated.  The rest of the error info is below.

If the issue occurs with the Links folder renamed then at least you can rule that out.  I would start by checking all of the PO_*TaxSummary and PO_*TaxDetail tables for any TaxCode values that are not on file in the SY_SalesTaxCode and/or SY_SalesTaxCodeDetail tables.

HI All,  Well finally figured out the issue.   Tried manually deleting some of the old POs that were not getting deleted and got a message about the line having activity which was not a standard message.   I had completely forgotten that I wrote scripts for them around 8 years ago to prevent deleting lines with activity.  Removed them and Period End worked fine.   

  Going to put on a cast were I shot myself in the foot....  .  

You could add a filter to your script to check the coSession.StartProgram property or even check if oScript.UIObj is not 0, then set it has an object and check the value returned by the GetScreenName() method to see if it is PO_PurchaseOrder.M4L (I would convert both to uppercase to rule out case-sensitivity causing it to fail).  Another option is to use the UI object's GetValue method to get the value of the "_class$" property, you would want it to be PO_PurchaseOrder_UI (Purchase Order Entry) in order for your script to proceed.

I also like using the oSession.Updating property which will not be equal to 0 if the script is triggered by a register update but off the top of my head, I don't know if the period end processes set this property.
