I'm trying to run reports using PARR++. When I import the data, I get the following error message: The INSERT statement conflicted with the FOREIGN KEY constraint “FK_InPatient_Admissions_Patients
What is the problem?

The most likely reason for this is that you have embedded blanks in your NHS numbers. Please ensure that no blanks exist. E.g. the number "123456789 " will not be recognised by PARR++ but "123456789" will be.

I get the same error message but I do not have embedded blanks in any of my NHS number records. Would either of the following affect PARR's ability to import the data:

1) blanks or brackets in any of the column field names?
2) NHS number being set as a 'text' field in Microsoft Access?

I should have a added a third possibility for the error - would an asterisk within any of my 'Hospital Provider Spell Number' cause an error?

I don't know if you've resolved this yet.
I receive foreign key error messages if I have any blank NHS Number or Hospital Provider Spell Number or any spaces in either of these fields.
Once corrected my data imports with no errors.
