MS Access to MS Excel export with VBA coding in MS Excel where having issue

Question

Below is my code where I'm trying to export a MS Access query output to an Excel file and then editing the Excel to create a pivot table on a new sheet.

The code works fine every alternate time I run the code i.e. on the 1st, 3rd, 5th, 7th time it is run.

When it is run 2nd, 4th, 6th, 8th time it gives an error pointing to the line numbers 74-76 for the TableDestination field where the Activecell is used.

How can I decode the issue with this line?

Answer 1

I seem to have found the solution to this problem by some trial & error method. The issue was resoled when I replaced the ActiveCell.with xls. and ran the code multiple times which fortunately worked.

Every time I ran the code earlier, the excel instance was not being closed due to the ActiveCell.reference. But when I used xls.the excel instance in the memory was properly getting closed by the code at the end of the subroutine.

Thank you for all the people who gave me a direction to think on this issue.
