Stored Data Reader Error

ERP 10
#1

ERP Version: Epicor 10.1.500.22
SQL Version: 2016 (130)

Problem Category: Sales Configured Parts and Jobs

I’m trying to troubleshoot and error I’m getting when either creating a Configured Part or creating a Job for a configured part.

Usually when I get this error it’s an SQL error where I have a partial transaction log stuck and I just run a ‘Simple’ backup and clear out the transaction log. That was back in SQL 2000 and I haven’t had an error like this in years.

Has anyone run into this before?
Thanks for your help,
Jonathan

#3

I am having this same error when trying to delete a demand link for a configured part or trying to get details. Have you brought this up with Epicor or figured out what was causing it?

#4

We did figure out the problem after I created a Deadlock monitor on the SQL server. It turned out to be a problem with the Configuration’s Method Rule Code. After deleting the Rule and rewriting it everything worked again.

#5

Do you ever have it where your get details form just hangs and never does anything? We are not receiving the error anymore, but it seems to just hang.

#6

Yes, it tries to unlock the data store that it locked. You have to find the Method Code that’s blocking the read and delete it.

#7

It’s strange because there has never been a time where it has locked until now and we have not added any new method rules in the past 3 weeks. Not sure what is happening. It happens when I try to Delete Details as well and when I try to delete the demand link.

#8

This is a Sales Order Configurator issue. Make sure your looking at the Method Rule Code. Did someone update the Method Rule Code in the Configurator?

Also, you may want to look at creating a Deadlock monitor or graph on the SQL database. See which tables are being locked during the process. I explained the steps we took to determine the issue and what we did to fix it above.

#9

ok so what happens when you get this “lock request time out period exceeded” in things like MRP logs and multi-level pegging process… we are not using configured parts or quote. We don’t even own the configured parts module. we are on 10.1.500.31 currently. Any info is appreciated on how to find or locate the locks and what is causing them.
