I have Update sheet, this sheet contains unique ID that matched the access database ID, I'm trying to update the fields using excel values in "Update" sheet.
The ID is in the Column A the rest of the fields are stored from Column B to R. I'm trying to achieve the below, As follows:
1. Update the record(values from Column B to R) if Column A (ID) matched existing Access database ID. Then add text in Column S "Updated"
2. If the Column A (ID) did not found any match in the existing Access database ID, Then add text in Column S "ID NOT FOUND"
3. Loop to next value
So far, I have the below Sub for Update and Function for Existing ID (Import_Update Module), but I'm getting this error.
Sub Data Update
