Sage 100

Did you double-check the file paths?  There are a couple things that could cause the database files to be in a path other than you are expecting...

Yes I checked the path last night.

I think I may have fixed it and I'm not sure exactly what happened although the steps I just took are: 

Used the instructions to reinitialize the PO Receipt of Goods data entry files ( here ) 

To reinitialize the Purchase Order Receipt of Goods/Receipt of Invoice Data Entry files, perform the following:

1. Open Library Master, Utilities, Reinitialize Data Files
2. In the Company field, select the affected company code
3. In the Module field, select Purchase Order
4. Select the following files:
   • PO_ReceiptDetail
   • PO_ReceiptHeader
   • PO_ReceiptRestart
   • PO_ReceiptReturnMatRqByPO (also used by PO Return of Goods data entry)
   • PO_ReceiptTaxAllocation
   • PO_ReceiptTaxDetail
   • PO_ReceiptTaxSummary
   • PO_ReceiptTierDistribution
   • PO_ReceiptVarianceCalculation.m4t
5. Click Proceed and Yes to warning

Since I was having an issue with landed cost I also re-initialized PO_LandedCostReceipt

After I did the reinitialize to the above listed files I went back and tried to create a landed cost against a test PO and it worked without generating an error message.

The end user is still verifying that this resolved the issue.

Possible contributing factor is that I had changed the MAS_USER and MAS_Reports password at some time in the last 30 days(ish) and this end user has been working on and off at trying to get going with PO so it's possible though not entirely certain that some type of issue arose because of a password change ( which I did through standard Sage Premium utility ). I only would suspect this because the nature of the error number 15 tends to indicate an OS type error.

If I get any additional feedback I will update this post. i may also throw this summary in our library with the full error message for future searches.

Additional screenshots: 

Full text of the initial error (as shown in the screenshot in my initial post )

The user called back and said the issue re-appeared. What I did to (hopefully) resolve the problem was to manually increase the DB size reserved for the SQL table. I also significantly increased the autogrowth amount.

What convinced me it was a space problem was when I looked at the SPACE AVAILABLE

I raised both size and autogrowth and that seemed to cause the issue to resolve. I don't know why SQL didn't automatically fix the issue except maybe the old autogrowth number ( 50 MB ) was too small. I replaced 50 with 2048.

Will keep watching and advise if any further action needed

They should get a DBA / SQL specialist to take a look.  That kind of issue is purely SQL, not Sage.
