There were no errors in Data Integrity

I do a data integrity check at the end of each week or sooner if I receive error messages.

My Repeat Errors

OE errors tend to be "item shipped but not costed at loc 1 is 49.00 calc 0.00"

Inventory errors do not give me an explanation only that the error is located in
"I/C items ... 2errors"

A/R error example-
show customer# "history transaction 123 missing matching information, computed balance - 73.35"

A/P error example-
"matching record for vendor # transaction IN 1413 found but not matched to existing transaction"

Does this mean there may be damage to my history files??

If there is a connection issue between my computer and network (quick glitch), can this cause these issues?????? (example program not responding message)
