Database Lock on Custom Ztable

$

Dear DB Gurus

We have created a solution in SAP for EH&S where data from the Spec DB gets analyzed

and returns results that gets posted to the Spec DB. Inorder to reduce data to be sent across

the network we have created some custom Ztables to store the date time stamp the spec was

synchronized with the third party tool.In order to achieve this we run this program in background

thru a customer enhancement so the user doesn't have to wait while this is happening.

We run this custom program as step 2 as there is a standard SAP Inheritance program that

runs to transfer data across the specs.What we noticed at one of the client is that if two

users edit specs and this program gets trigerred  at the same time the program grinds for hours.

There is a "Modify" Statement in the custom program for the Z table and it does not pass that statement.

In fact this process has to be killed each time as they continue to run for more than a day.

We did not notice this issue at any other clients .

Could any one throw some light on what DB settings need to be used on the table

or is this some thing related to the client DB settings which as a programmer we do not have control

over.Any help is deeply appreciated.

 

Thanks
