Is there any reason why you are using two users in stead of one? Does each user have all accesses to the other user's tables, etc? Instead of two forms can you do it through one form using a master - detail relationship? Are there any error messages being displayed?

Thanks for the reply ,I have 2 users and both users are using a different system.

RO user is related to all activity related to car maintainance and parts user is related to all parts in and out .

When car comes into our workshop the following activites have done.
1-Ro user input all information of car into RO system (RO no Primary key)
2-RO user enerate request of required part with reference to RO no.
3-Part user received request and issue parts and generate invioce against RO NO.
4-After Issuing of parts from Parts Dept against RO NO ,RO user open RO Form in Enter query mode and then i am using key next item for extracting all parts issue.

at that moment some time the system is look like busy and then hang.

I am giving all grant to ro user for using all parts table

Okay. I have had a quick look at your form.

General comment: You are referring to items by their item name without their block level qualifier. This is bad practice. I suggest modifying ALL your code to add the block name.

At the form level you have placed 'null;' in the on-error trigger. I suggest that you either let the errors appear on the screen or log them to a flat file.

In 'ro_mst.ro_no' key-next-item trigger you have a 'delete' statement but no 'standard.commit'. It is possible that this statement is locking the row and this could cause contention.

Don't use the 'post-change' trigger as it has been superceded. Use 'when-validate-item'.

Do you have access to TOAD or a TOAD-like development tool? If so, when a contention is reported use the 'Session Browser' to look for 'Locks'.

Use 'text_io' or 'utl_file' to create and write to a flat file. Search this forum.

For TOAD either google it or look at this site's FAQ.
