Query on Co-ordination Operation -Go_Record

Question

I've a Master database block and it is having only one record.For the Master Block,Details block was created with the Co-ordination Property-Defered:NO and Automatic Query:NO.
After using POST command,I'm using GO_BLOCK and GO_RECORD on master block in Key-Commit Trigger, at the time :system.form_status was in QUERY and Detail Block status was QUERY.
Question:
When i issue GO_RECORD on master block,ON-CLEAR-DETAILS trigger was getting fired and which inturn clears the detail block.
My Understanding:
Co-ordination Event should occur only when the event makes a different master record as the current record, in the Master Block.In my case I've only one master record so the GO_RECORD on master block to the same record should not cause Co-ordination Event to occur.
Can any one help?

Answer 1

Hi,
Thanks.
But..,
This scenario was different. In Key-Commit trigger, I’m capturing the :System.Cursor_Record and :System.Cursor_Block to a variable inorder to store the current cursor placement at the time of commit and after doing all the validation on other blocks, I’m asking the system to go back to the same block using the value of the variable which has the initial cursor block and record value.
When user keeps the cursor at the master block and does the commit, value of the variable will be the master block. So the GO_RECORD of master block clears the value in the detail blocks. If the cursor is on other than the master block, System does not clear the detail block.
Here we can’t restrict user from placing the cursor and also GO_RECORD is used in *‘n’* number of places in the key-commit trigger based on many situation.
My Questions:
1)Will the GO_RECORD on master block will fire the Co-Ordination Event even if the master block has only one record?
Also I’ve confirmed that the master block is having only one record by checking: SYSTEM.Last_Record value after the GO_RECORD statement.
2)As I said: I'm Using the GO_RECORD of master block after the POST command, the Form Status and the Block Status of Master & Details
block will be QUERY
As the Block status was in Query, System does not re-query the record after the block is cleared.
Below code is System generated code in CLEAR_ALL_MASTER_DETAILS
currel := Get_Block_Property(trigblk, FIRST_MASTER_RELATION);
WHILE currel IS NOT NULL LOOP
curdtl := Get_Relation_Property(currel, DETAIL_NAME);
IF Get_Block_Property(curdtl, STATUS) <> 'NEW' THEN
Go_Block(curdtl);
Check_Package_Failure;
Clear_Block(NO_VALIDATE);
IF :System.Block_Status <> 'NEW' THEN
RAISE Form_Trigger_Failure;
END IF;
END IF;
currel := Get_Relation_Property(currel, NEXT_MASTER_RELATION);
END LOOP;
As the Clear_Block(NO_VALIDATE); clears the detail block and the Block status is in Query so RAISE Form_Trigger_Failure is called.As the result the detail block was not populated after the clear block statement.
Can u clarify me on this?.
