Re Accounts Receivable Module
When I tried to open an accounts receivable invoice batch I got an error message that said "Error 4102 occurred when attempting to apend record to A/R batch control file"

Please advise

AR Version? Any recent changes? Is this new behaviour? Does it happen on another workstation?

Version 9.0A. No recent changes. This is new behaviour. Our other workstation has the same problem. Our contact at Accountability, Linda, wonders if it might have to do with our automatic antivirus updates.

I had CLWD run a data integrity check on her AR data and it dies before it gets to the Application DIC. So now she's got corrupt data and we'll have to restore her AR data from backup. Curiously, just before responding to CLWD, I had a call this morning from another client regarding a problem with their AR invoice batch entry that just happened this morning. Yesterday Elke was entering AR invoices just fine but today it won't let her enter the header screen info, it goes directly into the invoice detail screen. But the SYS user can get into invoice entry header and detail screens with no problems at Elke's pc. According to her IT guy there haven't been any upgrades to the AV software and will be checking out any other updates that may have been installed overnight ... CLWD and this other client are running the same ver of Win XP 2.002.

Error 4102 tends to be corrupted data. Do a data backup, a Data Integrity Check, and a Rebuild if errors are found.

Not able to do a rebuild after doing the check (application integrity skipped due to errors in file integrity)

That means you need a database repair, or restore a clean copy of your data from a backup. Linda can help.
