I have Datacare that runs on a nightly basis, but due to issues I was having with IC I decided to run Data Integrity Checks on all the modules individually. I recently upgraded my modules and they came up clean in Integrity checks before the upgrades.

All my modules are fine except for AR. I've run two data integrity checks and it's coming up with errors in Import export file header, first I had 11 errors, now 1 error. Data integrity then says skipped due to errors in file integrity.

Do you know why this is happening and is if safe to rebuilt?
I'd thought I'd ask here first before I did anything. thanks
